Run unit tests in IntelliJ with errors in classes

Question

I am new to using IntelliJ. I have only one grievance and that's the compiler. I prefer the way the Eclipse compiler will compile a project and skip classes with errors in them.

This is particularly a problem for if I want to write a unit test for a method I have to fix all errors in the entire project for running a single unit test!

You might say fix your project but I'm working on a project where people have already committed code with errors in it. How can I get around this, I saw there's an option to use the Eclipse compiler in the settings but this has made no difference/I don't know the argument to skip errors.

Answer 1

This fixed it for me on IntelliJ 14:

• In Preferences->Build,Exec,Deploy->Compiler->Java Compiler, choose Eclipse compiler. Then check "Proceed on errors", which will appear once you choose the Eclipse compiler.
• Then in Run->Edit Configurations expand the Defaults section on the left. Choose the configuration for your unit test framework (eg, JUnit or TestNG).
• Then in the "Before launch" section, remove "Make" and add "Make, no error check"
• Finally, you may need to delete any existing unit test run configurations so the new launch setting will take effect.

Answer 2

Not sure if this will be effective for what you're attempting to do and how your project is structured, but it worked perfectly well for me in my particular case, in that if your class has a main method, you can right click inside of the actual main method code and select "Run 'classname.main()'" from there.

This worked for me, but obviously may not be identical to your situation.

I got this from another answer located here: Intellij IDEA how to run a class not the entire project?
