Learn how to run Selenium Java tests in Azure DevOps.

Mastering Selenium

We all write automated tests using Selenium WebDriver and Java. While developing and testing our automation code, we run it locally on our computers. Others should be able to change or run the code as well. This becomes possible when the code is added to a repository, from which other people can also access it. Once the code is in a repository, it can be executed in a CI/CD environment—such as Jenkins or Azure DevOps—through pipelines. This is the focus of this module.
 
In this module, we’ll add a local automation project built with Java, TestNG, and Selenium to an Azure DevOps project, share the repository with other people, and run its tests through pipelines.

Run Selenium Java Tests in Azure DevOps

To make tests fail, we will modify the `data-key` attribute of the `PAGINATION_TEXT_XPATH` locator from the `ResultsPage`  class by adding 1 to its value:<br/>


By PAGINATION_TEXT_XPATH = By.xpath("//span[@data-key = 'pagination-text1']");

## Run tests
Next, we run the `mvn test` command. This time, because of the invalid locator, all 3 tests fail with the error `"Unable to locate element"` (line 48):


# Run tests
Next, we run the `mvn test` command. This time, because of the invalid locator, all 3 tests fail with the error `"Unable to locate element"` (line 48):
