Developing End To End Tests With Selenium 4 And Java | Boni García | Testμ 2022

About The Talk

Selenium WebDriver (also known as simply Selenium, like its umbrella project) is an open-source library that allows programmatic control of web browsers using various languages including Java, JavaScript, Python, Ruby, and C#. Its primary application is to run end-to-end tests on web applications. Nonetheless, Selenium WebDriver is not a standalone testing library. As a result, other ingredients will be required for web testing with Selenium WebDriver.

This talk goes over how to write end-to-end tests for web applications using Selenium 4 (due out in October 2021) and Java. To that end, we'll go over the build tools (Maven, Gradle), unit testing frameworks (JUnit 4/5, TestNG), and assertion libraries (AssertJ) needed to create comprehensive Selenium WebDriver tests. Furthermore, you will learn about two end-to-end test helper tools, WebDriverManager (for automated driver management and other features) and Selenium-Jupiter (JUnit 5 extension for Selenium WebDriver).

Key Topics Covered

Introduction to Selenium: The video begins with an overview of Selenium, defining it as a suite of tools for automating web browsers. The speaker emphasizes that Selenium is more than just a testing tool; it's a browser automation library that supports various programming languages.

Components of Selenium: The video details the three main components of Selenium: Selenium WebDriver, Selenium IDE, and Selenium Grid, explaining the purpose and functionality of each.

Selenium WebDriver: The speaker dives deep into Selenium WebDriver, discussing its importance as the core of Selenium for controlling browser actions programmatically using Java, JavaScript, Python, etc.

Testing Frameworks and Libraries: A significant portion of the video is dedicated to explaining the necessity of integrating Selenium with a testing framework (e.g., JUnit, TestNG) and the role of assertion libraries (e.g., AssertJ, Hamcrest) in enhancing test readability and error message clarity.

Practical Examples: The video includes practical coding examples showing how to set up Selenium tests, emphasizing the use of WebDriverManager for driver management and the benefits of using an assertion library for more fluent assertions.

Docker Integration: An interesting part of the video showcases how to use Selenium tests in Docker containers, enabling testing in a consistent, isolated environment.

Advanced Selenium Features: The speaker covers advanced Selenium features, such as browser version testing, use of Docker for testing across different browser versions, and integration with testing reporting tools for enhanced test reporting.

Q&A Session: The video concludes with a Q&A session where the speaker addresses questions from the audience, providing further insights into Selenium's capabilities, best practices for using WebDriverManager, and recommendations for test reporting tools.
