Руководство по сквозному тестированию: что такое E2E-тестирование с примерами

Сквозное тестирование (End-to-end, E2E, Chain testing) — это вид тестирования, используемый для проверки программного обеспечения от начала до конца, а также его интеграцию с внешними интерфейсами. Цель сквозного тестирования состоит в проверке всего программного обеспечения на предмет зависимостей, целостности данных и связи с другими системами, интерфейсами и базами данных для проверки успешного выполнения полного производственного сценария.

Наряду с программной системой тестирование также обеспечивает проверку пакетной обработки и обработки данных из других вышестоящих и нижестоящих систем. Отсюда и название «End-to-End». Сквозное тестирование обычно проводится после функционального и системного тестирования. Для его проведения используются реальные данные и тестовая среда для имитации рабочего режима.

Зачем нужно сквозное тестирование?

Сквозное тестирование проверяет весь системный флоу и повышает уверенность за счет своевременного обнаружения проблем и увеличения покрытия тестами подсистем. Современные системы ПО сложны и взаимосвязаны с большим количеством подсистем, которые могут существенно отличаться от существующих систем. Вся система может разрушиться из-за отказа любой подсистемы, что представляет собой серьезный риск. Этого риска мы как раз и стремимся избежать с помощью сквозного тестирования.

Процесс сквозного тестирования:

На схеме ниже представлен обзор процесса сквозного тестирования.

Основные виды деятельности, связанные со сквозным тестированием:

Изучение требований к сквозному тестированию;

Настройка тестовой среды и требования к оборудованию/программному обеспечению;

Описание всех процессов системы и ее подсистем;

Описание ролей и ответственности для всех систем;

Методология и стандарты тестирования;

Сквозное отслеживание требований и разработка тест-кейсов;

Входные и выходные данные для каждой системы.

Как писать тест-кейсы для сквозного тестирования?

Фреймворк сквозного тестирования включает в себя три части:

Создание пользовательских функций

Рассмотрим каждую из них подробно.

Создание пользовательских функций

Как часть построения пользовательских функций, должны быть выполнены следующие действия:

Перечислить функции системы и их взаимосвязанные компоненты;

Перечислить входные данные, действия и выходные данные для каждой характеристики или функции;

Определить отношения между функциями;

Определить, является ли функция многократно используемой или независимой.

Например, рассмотрите сценарий, при котором вы входите в свой банковский аккаунт и переводите деньги со своего счета на счет в другой банк (сторонняя подсистема):

Войти в банковскую систему.

Проверить сумму остатка на счете.

Перевести определенную сумму со своего счета на другой банковский счет (сторонняя подсистема).

Проверить текущий баланс счета.

Выйти из приложения.

Построение условий на основе пользовательских функций

В рамках построения условий выполняются следующие действия:

Построение набора условий для каждой определенной пользовательской функции;

Условия включают последовательность, время и условия данных.

Например, проверка дополнительных условий, таких как:

Страница авторизации

Неверное имя пользователя и пароль

Проверка с действительным именем пользователя и паролем

Проверка надежности пароля

Проверка сообщений об ошибках

Сумма остатка

Проверьте текущий баланс через 24 часа (Если перевод отправляется в другой банк)

Проверьте сообщение об ошибке, если сумма перевода больше суммы текущего баланса.

Создайте тестовый сценарий

Построение тестового сценария для определенной пользовательской функции

Войти в систему

Проверить сумму остатка на банковском счете

Перевести сумму остатка на банковском счете

Создание нескольких тест-кейсов

Создайте один или несколько тест-кейсов для каждого определенного сценария. Тест-кейсы могут включать каждое условие как отдельный тестовый пример.

Доступность среды — общее количество часов доступности / общее количество часов, запланированных в день для тестирования.

Сквозное тестирование vs системное тестирование

Сквозное тестирование

Системное тестирование

Проверяет программную систему, а также взаимосвязанные подсистемы.

Проверяет только программную систему в соответствии со спецификациями требований.

Проверяет весь сквозной поток процессов.

Проверяет функциональные возможности и функции системы.

Для тестирования рассматриваются все интерфейсы и серверные системы.

Рассматриваются функциональное и нефункциональное тестирование

Выполняется после завершения тестирования системы.

Сквозное тестирование включает в себя проверку внешних интерфейсов, которую сложно автоматизировать. Следовательно, ручное тестирование предпочтительнее.

Для тестирования системы можно выполнять как ручное, так и автоматизированное тестирование.

В заключение

Сквозное тестирование — это процесс проверки программной системы вместе с ее подсистемами. Самая большая трудность при этом типе тестирования состоит в том, что необходимо располагать достаточным количеством информации о всей системе, а также о взаимосвязанных подсистемах.

Приглашаем всех желающих на открытое занятие, на котором мы познакомимся с фреймворком Selenide и перепишем существующие тесты на него. Регистрация доступна по ссылке.

E2E Testing

End-to-end (E2E) testing is a Software testing methodology to test a functional and data application flow consisting of several sub-systems working together from start to end.

At times, these systems are developed in different technologies by different teams or organizations. Finally, they come together to form a functional business application. Hence, testing a single system would not suffice. Therefore, end-to-end testing verifies the application from start to end putting all its components together.

Why E2E Testing [The Why]

In many commercial software application scenarios, a modern software system consists of its interconnection with multiple sub-systems. These sub-systems can be within the same organization or can be components of different organizations. Also, these sub-systems can have somewhat similar or different lifetime release cycle from the current system. As a result, if there is any failure or fault in any sub-system, it can adversely affect the whole software system leading to its collapse.

The above illustration is a testing pyramid from Kent C. Dodd’s blog which is a combination of the pyramids from Martin Fowler’s blog and the Google Testing Blog.

The majority of your tests are at the bottom of the pyramid. As you move up the pyramid, the number of tests gets smaller. Also, going up the pyramid, tests get slower and more expensive to write, run, and maintain. Each type of testing vary for its purpose, application and the areas it’s supposed to cover. For more information on comparison analysis of different testing types, please see this ## Unit vs Integration vs System vs E2E Testing document.

E2E Testing Design Blocks [The What]

We will look into all the 3 categories one by one:

User Functions

Following actions should be performed as a part of building user functions:

• List user initiated functions of the software systems, and their interconnected sub-systems.
• For any function, keep track of the actions performed as well as Input and Output data.
• Find the relations, if any between different Users functions.
• Find out the nature of different user functions i.e. if they are independent or are reusable.

Conditions

Following activities should be performed as a part of building conditions based on user functions:

• For each and every user functions, a set of conditions should be prepared.
• Timing, data conditions and other factors that affect user functions can be considered as parameters.

Test Cases

Following factors should be considered for building test cases:

• For every scenario, one or more test cases should be created to test each and every functionality of the user functions. If possible, these test cases should be automated through the standard CI/CD build pipeline processes with the track of each successful and failed build in AzDO.
• Every single condition should be enlisted as a separate test case.

Applying the E2E testing [The How]

Like any other testing, E2E testing also goes through formal planning, test execution, and closure phases.

E2E testing is done with the following steps:

Planning

• Business and Functional Requirement analysis
• Test plan development
• Test case development
• Production like Environment setup for the testing
• Test data setup
• Decide exit criteria
• Choose the testing methods that most applicable to your system. For the definition of the various testing methods, please see Testing Methods document.

Pre-requisite

• System Testing should be complete for all the participating systems.
• All subsystems should be combined to work as a complete application.
• Production like test environment should be ready.

Test Execution

• Execute the test cases
• Register the test results and decide on pass and failure
• Report the Bugs in the bug reporting tool
• Re-verify the bug fixes

Test closure

• Test report preparation
• Evaluation of exit criteria
• Test phase closure

Test Metrics

The tracing the quality metrics gives insight about the current status of testing. Some common metrics of E2E testing are:

• Test case preparation status: Number of test cases ready versus the total number of test cases.
• Frequent Test progress: Number of test cases executed in the consistent frequent manner, e.g. weekly, versus a target number of the test cases in the same time period.
• Defects Status: This metric represents the status of the defects found during testing. Defects should be logged into defect tracking tool (e.g. AzDO backlog) and resolved as per their severity and priority. Therefore, the percentage of open and closed defects as per their severity and priority should be calculated to track this metric. The AzDO Dashboard Query can be used to track this metric.
• Test environment availability: This metric tracks the duration of the test environment used for end-to-end testing versus its scheduled allocation duration.

E2E Testing Frameworks and Tools

1. Gauge Framework

Gauge is a free and open source framework for writing and running E2E tests. Some key features of Gauge that makes it unique include:

• Simple, flexible and rich syntax based on Markdown.
• Consistent cross-platform/language support for writing test code.
• A modular architecture with plugins support.
• Supports data driven execution and external data sources.
• Helps you create maintainable test suites.
• Supports Visual Studio Code, Intellij IDEA, IDE Support.
• Supports html, json and XML reporting.

2. Robot Framework

Robot Framework is a generic open source automation framework. The framework has easy syntax, utilizing human-readable keywords. Its capabilities can be extended by libraries implemented with Python or Java.

Robot shares a lot of the same «pros» as Gauge, except the developer tooling and the syntax. In our usage, we found the VS Code Intellisense offered with Gauge to be much more stable than the offerings for Robot. We also found the syntax to be less readable than what Gauge offered. While both frameworks allow for markup based test case definitions, the Gauge syntax reads much more like an English sentence than Robot. Finally, Intellisense is baked into the markup files for Gauge test cases, which will create a function stub for the actual test definition if the developer allows it. The same cannot be said of the Robot Framework.

3. TestCraft

TestCraft is a codeless Selenium test automation platform. Its revolutionary AI technology and unique visual modeling allow for faster test creation and execution while eliminating test maintenance overhead.

The testers create fully automated test scenarios without coding. Customers find bugs faster, release more frequently, integrate with the CI/CD approach and improve the overall quality of their digital products. This all creates a complete end-to-end testing experience.

4. Ranorex Studio

Ranorex Studio is a complete end-to-end test automation tool for desktop, web, and mobile applications. Create reliable tests fast without any coding at all, or using the full IDE. Use external CSV or Excel files, or a SQL database as inputs to your tests.

Run tests in parallel or on a Selenium Grid with built-in Selenium WebDriver. Ranorex Studio integrates with your CI/CD process to shorten your release cycles without sacrificing quality.

Ranorex Studio tests also integrate with Azure DevOps (AzDO), which can be run as part of a build pipeline in AzDO.

5. Katalon Studio

Katalon Studio is an excellent end-to-end automation solution for web, API, mobile, and desktop testing with DevOps support.

With Katalon Studio, automated testing can be easily integrated into any CI/CD pipeline to release products faster while guaranteeing high quality. Katalon Studio customizes for users from beginners to experts. Robust functions such as Spying, Recording, Dual-editor interface and Custom Keywords make setting up, creating and maintaining tests possible for users.

Built on top of Selenium and Appium, Katalon Studio helps standardize your end-to-end tests standardized. It also complies with the most popular frameworks to work seamlessly with other tools in the automated testing ecosystem.

Katalon is endorsed by Gartner, IT professionals, and a large testing community.

Note: At the time of this writing, Katalon Studio extension for AzDO was NOT available for Linux.

6. BugBug.io

BugBug is an easy way to automate tests for web applications. The tool focuses on simplicity, yet allows you to cover all essential test cases without coding. It’s an all-in-one solution — you can easily create tests and use the built-in cloud to run them on schedule or from your CI/CD, without changes to your own infrastructure.

BugBug is an interesting alternative to Selenium because it’s actually a completely different technology. It is based on a Chrome extension that allows BugBug to record and run tests faster than old-school frameworks.

The biggest advantage of BugBug is its user-friendliness. Most tests created with BugBug simply work out of the box. This makes it easier for non-technical people to maintain tests — with BugBug you can save money on hiring a QA engineer.

Conclusion

Hope you learned various aspects of E2E testing like its processes, metrics, the difference between Unit, Integration and E2E testing, and the various recommended E2E test frameworks and tools.

For any commercial release of the software, E2E test verification plays an important role as it tests the entire application in an environment that exactly imitates real-world users like network communication, middleware and backend services interaction, etc.

Finally, the E2E test is often performed manually as the cost of automating such test cases is too high to be afforded by any organization. Having said that, the ultimate goal of each organization is to make the e2e testing as streamlined as possible adding full and semi-automation testing components into the process. Hence, the various E2E testing frameworks and tools listed in this article come to the rescue.

What is E2E Testing?

E2E Testing, as it will be defined here, is testing your system from the system’s user perspective. The key difference between E2E tests and other functional tests (namely: unit and integration) is as follow:

• In a unit or integration test the testing framework is playing the role of software CODE that is RUNNING the tested code. The testing framework calls the functions in the tested code and will wait for responses from the code. The testing framework is very aware of the internals of your code, such as your development language.
• In an E2E test, the testing framework is playing the role of a USER that is INTERACTING with the application like a user would do: click on the screen, input text and expect to see screen changes in response.

How do we E2E Test a system?

Here are some good news: if you are about to test an application from the end user’s perspective, you do not really care about the internals of the system. If we are referring to a browser based app (or a mobile app, but we will get to that later), then all you have to do is run a browser and interact with it. You need to find a certain input field, paste some value, click on a button and wait until the system has reacted.

Was the front end developed in React, Angular or Vue? who cares. Is the backend based on Nodejs or Java or PHP? As long as it works it is fine. All is required is this magic system that will find this input field and button and will know how to interact with them .

Meet Selenium

This is where Selenium comes into picture. Selenium (actually: Selenium WebDriver) is a tool for automating web application testing, and in particular to verify that they work as expected.

Selenium originally started at 2004. Its original version was called Selenium RC (Remote Control), or Selenium 1.0. It worked by injecting javascript into the browser and executing its functions.

Later, Selenium was evolved into Selenium Webdriver, which uses the browser APIs to execute the required commands. Here is Selenium Webdriver’s architecture:

How Does it Work?

• Selenium language bindings (in our favorite language) sends a JSON (HTTP) to the Selenium Server.
• The server receives the request and translates it to the browser’s specific APIs
• The server sends the request to the browser.
• Browser executes the requests and send the response back to Selenium server
• Selenium server returns the response the the HTTP request response.

Let’s make this a bit more real:

Language Bindings: Create me a new session with the following characteristics: enable js, enable location and more…

Selenium server: I hear you. Here is the session Id I created for you!.

LB: Great. Can you now go to that url I am sending you?

SS: yep! (no result body, just returning status code).

LB: Can you find me an element on page using the css selector #welcome

SS: Found it — here is its ID. Go ahead and use it if you want to do anything with this element.

And so on and on…

What are those APIs?

The APIs that are now part of the spec that is governed by W3C (the web committee). They are called Webdriver APIs and are defined here. Those API are not yet an official standard, but this is likely to occur at some point. Another useful link points to the implementation status of the APIs in the major browser. It is a great source to check when your tests do not work as expected.

But, what is Selenium Language Bindings Anyway?

Because the APIs are a standard, we can use any language to trigger them. So if you would like to write your tests in Java — go ahead. C++ or C#? sure. The language binding is running your tests and translates them to the JSON requests. Selenium originally was developed in Java, but later Language Bindings were added in other languages. You can see the various official language bindings in the Selenium official repository.

Selenium-less Selenium

So, in order to test on a browser, we need to set a language binding server that will call the APIs, and a Selenium Server that will receive the Webdriver API requests and will dispatch the requests to the right browser.

This is true, BUT there is also a shortcut: the major browsers (read: Firefox, Chrome and lately Safari) can receive the HTTP API calls directly without the need to install Selenium Server. This means that in order to test chrome you can simply install Chromedriver locally and send the requests to the default port 9515. Chrome will execute the commands and respond without the need to go thru the Selenium Server.

So if you are using non official language bindings, such as webdriverio, and a direct browser connection to, let’s say Chrome, you are running “Selenium” like tests (in fact — webdriver) without really using or installing Selenium itself.

Selenium Grid

One additional term you may encountered is the Selenium Grid. This is required when you are running multiple browsers or multiple operating systems. The Selenium Grid keeps track of all your sessions and will direct the correct session request to the relevant browser. If you are testing against single browser, this is not needed — see Selenium-less.

E2E Testing tutorial: Complete Guide to End to End Testing With Examples

11 Min Read

E2E Testing also called End to End testing, is a very common testing methodology where the objective is to test how an application works by checking the flow from start to end. Not only the application flow under dev environment is tested, but the tester also has to check how it behaves once integrated with the external interface. Usually, this testing phase is executed after functional testing and system testing is completed. The technical definition of end to end testing is – a type of testing to ensure that behavioural flow of an application works as expected by performing a complete, thorough testing, from the beginning to end of the product-user interaction in order to realize any dependency or flaw in the workflow of the application.

Why End to End Testing is Required?

In the current Agile world, an application is interconnected and integrated with multiple systems that are outside of the application environment. The entire flow of the application thus gets complicated. End to end testing ensures that the application is tested from all layers – front end to backend along with its interfaces and the endpoints. Let’s see why it is needed.

Health of Back-end – End to end testing checks the database as well as backend layer of the application. Since the core functionalities of the application depend on the back end and database layer, testing this layer checks how accurately the application can perform the critical functions.

Errors in Distributed Environment – End to end testing makes it possible to test an application that is based on SOA or cloud environments. Also, in application consisting multiple components that require an all-around check, it helps to pinpoint problems in the core.

App Behavior Validation in Multi-tier System – In applications having a complex architecture or a workflow that is subdivided into multiple tiers, the end to end testing checks the overall functioning as well as functioning in individual layers. It also identifies the behavior of the application in connected systems.

Ensuring Interaction Accuracy – Since front-end testing is also involved, it is ensured that the application behaves accurately a provides a user experience that is consistent across multiple platforms, devices and environments.

Reusability of Test Cases – During different processes of the application’s lifecycle, the end to end testing provides the option to execute test cases that are repeatable. Moreover, it also increases the test coverage and makes the owner confident in the performance of the application.

Now that we have seen why the E2E testing is required, let’s see how it is carried out.

How End to End Testing is Performed?

Let’s summarize the key activities that are must to include during the end to end testing.

• Thoroughly analyze the requirements before starting the testing phase.
• Setting up the test environment following all the prerequisites.
• Analyze the software and hardware requirements ( both minimum as well as recommended configuration).
• Study the main system along with connected subsystems.
• List down the responsibilities of all systems involved.
• List down the testing methods along with the description of the standards to be followed.
• Design the test cases and while doing so also trace the requirement matrix.
• Save the output results and input data before testing each system.

Key activities being set, let’s dive in deep.

End to end testing process can be divided into 3 categories.

User Functions

As a part of user functions, the following activities should be performed.

• List down the software system’s features and the subsystems that are interconnected.
• Keep track of the actions performed for any functionality along with the input data and output results.
• Between different functionalities performed from the user’s end find out if there is any relation.
• Check whether the user functions are independent or can be reused. In short – find their nature.

Let’s explore a scenario that will help us to understand E2E testing. We’ll consider an online theatre booking service like BookMyShow.

1. Log into the application
2. Search for a movie show.
3. Book your seats.
4. Check the payment gateway.
5. Check the message confirmation for the booked tickets.
6. Logout from the application.

Conditions Depending On User Function

As a part of building conditions, do the following:

• For each user function, build a set of conditions.
• Conditions should include parameters like timing, data conditions, and sequence.

Considering our previous example of BookMyShow we can have the following condition check.
In the login page

1. Check whether error messages are reflected properly in case of incorrect password or username.
2. Check the same scenario with valid user details and see if login is successful.
3. Check the strength of a password.
4. Check email address validation.
5. Check the error messages if the amount to be transferred is greater than your wallet balance.

Payment page

1. Invalid pin.
2. Invalid CVV.
3. Invalid Debit/Credit credentials.
4. Validate all mandatory fields are working.

Build the Test Cases

Before building the test cases, consider the following factors.

• Write more than one test cases for every scenario and every functionality.
• Enlist each condition as separate test cases.

Watch this video to learn how to write end-to-end automation tests using Selenium WebDriver and perform cross browser and parallel testing at scale.

Parameters Involved During End to End Testing

Let’s move on to the important parameters that are involved during the end to end testing.

1. Test Case Preparation – An important thing to track is at what is the current state of the test case preparation. The tester can track this in form of a graph. It gives an idea of the progress of test case preparation (current vs planned).
2. The progress of Weekly Test – This provides a percentage base report of the test completion. Currently executed, not executed and failed test cases are compared weekly with the planned report.
3. Details of Defect – This report provides a percentage of defects that are closed or opened by the end of a week. Weekly distribution of defects based on priority and criticality is also taken into account.
4. Availability of Environment – This report provides a comparison of the total time scheduled for testing every day versus the total hours actually spent.

How Is It Different From System Testing?

After discussing all the aspects involved in End to end testing, let us discuss how different it is from system testing.
Before moving on to that, we should know what is system testing. It is basically a kind of black box testing, where the application is tested after integrating it with the external system. The testing is performed from a user’s point of view considering real-world conditions.
But how different it is from End to end testing? Well,

• System testing validates only the integrated software system whereas End to end testing checks both the main as well as interconnected systems.
• System testing checks features and functionalities of the system while E2E testing checks the complete flow of the system.
• Only non-functional and functional testing are considered in system testing, while in E2E testing, backend systems along with all other interfaces are considered.
• System testing is executed once Integration testing is completed. End to end testing is carried out immediately after system testing is completed.
• Both Automation, as well as manual procedures, can be used for System testing. However, for an end to end testing, the process gets much complex since it is hard to automate testing of external interfaces. Hence, manual testing is preferred.

Automation and E2E Testing

No matter how much advantageous, automation has a very little scope at the end to end testing. This is because of the following:

• The architecture of complex applications and more interconnected systems makes it difficult to write test cases.
• When database testing is involved, that requires constant updating and deleting table or data, it is impossible to write an automated script that can do the job.

However partial automation testing is possible. Especially with the UI layer of the application or testing the functionality, selenium web driver or related tools can be used to write automated scripts for partial testing.

Challenges Faced During E2E Testing

Although detecting bugs in a complex workflow is considered to be the biggest challenge in the end to end testing, apart from that there are other complications as well. Let’s take a look.

• Building a Workflow – The test cases in E2E testing must be executed sequentially. In a distributed workflow, it is difficult to manage a workflow where a thousand cases can be run in a sequential order.
• Access Issue – Custom applications can be tested easily in a virtual dev environment. The real challenge arrives when you have to test an offline application in client or production environment. There is limited availability of test environments and you have to install local agents and log in to virtual machines. After all of these, you will need to figure out a way to keep the machine on during the time of the test and prevent unforeseen situations like system updates from interrupting the execution of test cases.

Best Practices for E2E Testing

A typical end to end testing can be a lot of time-consuming when performed manually and a lot complex as well. However, following certain best practices will ensure a smooth completion of testing and efficient cost management. Let’s take a look at them.

• Test from the Perspective of an End User – Think like a user, focus more on features rather than how the functionalities are implemented. Use documents related to acceptance testing, user stories that will help you to capture the user’s point of view and design test cases accordingly.
• Limit Scenarios Involving Exception Testing – Use end to end testing only to capture typical user scenarios. For exception scenarios, use integration testing and low-level unit testing.
• Risk Analysis – This is an important thing to consider. Concentrate on the features of your application whose failure will cause high risk. A risk assessment matrix will become quite a useful tool for this purpose.
• Maintain an Order – With complexity in test cases and increasing components, points of failure also increases and it becomes difficult to debug them. How to avoid it? Execute unit testing and integration testing beforehand and resolve errors that are easier to detect. Once E2E testing starts, run smoke tests, sanity tests along with other high-risk test scenarios.
• Manage the Environment – Make sure the system set up for running the test cases are proficient enough. Document the requirements and make sure they are fulfilled by your system administrator before the testing starts. An easier solution is to follow the system requirement of the production environment. Also, to keep your staging environment as close to production as possible.
• Setup and Teardown Optimization – Make sure that your environment is ready to start the job at a moment’s notice. Once testing is done, clear the test data so that the environment is restored to the state it was originally and can be used anytime for another round of testing.

What The Future Has in Store?

With the advancement of IoT and the introduction of modern applications, we are seeing more and more interconnected applications with every device in our surrounding environment. Their workflow is a bit complicated but can be a lot beneficial.

Scenarios have often arisen when an organizational application is deployed at a place outside the organization and it failed, affecting business processes. Such situations can be avoided if an end to end testing is carried out effectively. It ensures that the application performs properly at all layers, especially when it is integrated with external systems.

With information technology growing more, the testing industry has already become a mandatory part of any software development methodology. If the correct solution and best practices are added, effort spends on end to end testing can be a lot beneficial. Also, with software systems getting more complicated day by day and as said before, IoT becoming the next top trend in the software industry, the future holds a lot in store for testing professionals specializing in End to end testing.
