For a client scenario I am building a custom Github Java Codespace. This client uses unit testing frequently. To that end I wanted to get JUnit up and running in the simplest possible way in my custom Codespace.

To do this I downloaded and then uploaded the two required JAR files (junit and hamcrest) to my jars directory in my Repo. Then I manually added each JAR file to the .classpath file.

I installed the following extensions.

• Java Extension Pack
• Debugger for Java
• Java Test Runner

Then I tried a sample test. I also tested the Java debugger (shown below).

My sample test was designed to fail in order to test the testing functionality. It worked as expected (shown below).
