Summary:

1. Selenium Web driveris an open-source UI test automation tool for web and mobile applications.
2. Java is a programming language and computing platform.
3. TestNG is an open-source test automation framework for executing test cases, grouping, generating reports, etc.
4. Maven can be used as it is a project management and build tool. It is a central repository for dependencies. It will automatically take care of all required environment setup of the Test Bed.

Usage:

1. UI Web Test Automation with Selenium Java with TestNG.
2. Easily integrate with Appium for Mobile Test Automation.
3. Easily verify all the links or Image links are working on the webpage.
4. Parallel execution on different OS/Nodes using selenium GRID.

Framework Structure:

The structure for the integration of selenium java with TestNG Maven framework.

Test Automation Framework Structure

Peculiarity:

1. Multi-Language Support: Selenium provides freedom to choose any programming language like JavaScript, PHP, Java, Python, C#, Perl, and Ruby to write our automation test scripts.
2. Multi-Browser Testing: Selenium interacts with web applications and its web elements in a browser, it supports multiple browsers like IE, Safari, Chrome, Firefox, Opera, and Edge.
3. Easy Identification of Web Elements and Dynamic Handling of Web Elements: With the help of locator’s methods like Xpath, CSS Selector, id, and class name identification of elements is easy. Selenium provides dynamic method handling with the Axes method like (contains (), Text (), Following-sibling, Preceding, Ancestor, Descendant)
4. Multiple OS Support: Selenium supports different Operating Systems like Mac, Linux, UNIX, as well as Windows. Test scripts created for selenium can work on different platforms and OS.
5. Annotations: TestNG provides different Annotations which are used to control the execution of the test scripts. In case any method is not prefixed with annotations, it will be ignored and will not be executed as part of the test script.
6. Assertions: To match the actual result and expected result TestNG provides assertion types like soft, and hard assertions.
7. Replay: While executing test scripts random failure may occur. These failures can be because of browser issues, hardware issues, Synchronization issues, etc. TestNG provides a retry mechanism to execute failed scripts automatically as per retry count.
8. Test Suite: As per the requirement we can group multiple test scripts and create multiple suites for the test scripts.
9. Well-Handled Synchronization: If the application slows down for any reasons like network, heavy load, test script, and application are not in sync then the script may fail. Selenium provides waits like:

• Implicit Wait
• Explicit Wait
• Fluent Wait

Test Reporting:

We can easily integrate multiple reporting like:

• Allure Report
• Extent Report
• XSLT Report
• Excel Report
• HTML Report

CI/CD Integration:

To schedule nightly job execution selenium TestNG supports multiple CI/CD tools like Jenkins, Bamboo, TeamCity, etc.

Supplement:

1. Easy prioritization, parallel execution, and data provider with Excel are possible.
2. Wide community support for Selenium with Java and TestNG.
3. Good documentation.
4. Easy integration with test management tools like JIRA, Dev Azure, etc.
5. Selenium supports TDD/BDD in both design approaches.
6. Easy Integration with any unit testing framework like JUnit, TestNG, etc.
7. Easy integration with Maven, Gradle, etc.
