Is it possible to run incremental/automated JUnit testing in Eclipse?

Question

Eclipse support incremental compiling. If I save a source file then it will compile the modified files.

Is it possible after such incremental compile also to run the JUnit tests of the same package and show the fail in the error view. Then I can see the JUnit test failing and compiling errors in the same view without extra action. Are there any plugins that can do it?

Answer 1

You have to look at these plugins:

• JUnit Max: Not free, developed by Kent Benk (one of the men behind the TDD practice);
• MoreUnit: Free, but essentially dedicated to help you write the tests;
• Infinitest: Now free, this plugin is dedicated to run the tests related to the files you have just modified.

So regarding your needs, I suggest that you install MoreUnit and Infinitest plugins.

Answer 2

Use ExternalToolBuilder.

It can be triggered by source modify.

There’s Eclipse customized feature(integrate external tool builder) which may meet your need. But it needs extra effort to write the scripts I never used. Automatic test cases is not a convenient way, at least single click to see green bar in Eclipse is enough for me:)

Answer 3

You can run all tests in a project using Alt+Shift+X,T. I think that making it any more automated than this could take a serious performance toll. Incremental compilation is compiling at most 1 file at a time, but you're talking about running potentially hundreds of tests.
