Welcome to VS Code update for Java. Another busy and productive month. Debugger for Java and Java Test Runner extensions got new features. Before jump into details, we would like to remind Microsoft Build 2021 is coming. You will hear more about Java and VS Code this time, so please join us.

Inline Values and Customized Variables View for Debugging

By adopting a new debugger extension API, Debugger for Java extension is now able to show variable values inline in editor when stepping through source code.

Both features were demonstrated at VS Code 1.56 Release Party. Check out here for more details.

Generating Tests

Automatically generating testing method templates and importing testing packages is a handy feature to improve coding efficiency. Starting from April, you can generate the method templates directly from a test file. In May, we will also add support for generating from a source file.

To generate testing method templates, open or create a test file under project’s test folder, right-click on file editor to invoke context menu, select “Source Action…” and then “Generate Test…”, and finally select methods to generate.
