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.

To define how the container will be executed

What is the purpose of the Dockerfile?

From an existing Docker image for Windows

How is the Docker image for Selenium tests created?

How is the Docker image for Selenium tests created?

Nothing needs to be installed as the Selenium image has everything that is required.

What software needs to be installed in the Docker image so that Selenium tests can be executed?

What software needs to be installed in the Docker image so that Selenium tests can be executed?

It installs both bash and command .sh in the Docker image.

It specifies that both bash and `command.sh` are to be executed after the container is started.

It specifies that after the container is started, bash will run in the container with the `command.sh` as a parameter.

What does this line from Dockerfile do?

`ENTRYPOINT ["bash", "command.sh"]`

What does this line from Dockerfile do?
<code>ENTRYPOINT [&quot;bash&quot;, &quot;command.sh&quot;]</code>

`.` refers to the root folder in the automation project.

`.` refers to the parent folder of the automation project folder.

`.` refers to the current folder, both in the host system (local computer or virtual machine) and in the Docker container.

What does `.` mean in the `COPY . .` command?

What does <code>.</code> mean in the <code>COPY . .</code> command?
