在IntelliJ中运行JUnit而忽略不相关类中的编译错误？

Question

When running a JUnit test case in IntelliJ it opens up the Make console and shows complication errors in an unrelated class.

1. Can I run the test case ignoring these errors?

2. Is there a way to make it not compile the entire project when running the test cases but only those class files required by the test case?

Answer 1

Yes you can.

You can disable the Make before Run.

(The following is written for IntelliJ 14, different versions might have slightly different layouts, but as far as I can remember these options have been the same for a while)

For a single test

• Go to "Run" - "Edit Configurations..."
• Select the configuration of your test case
• In the tab named "Configuration" there is a List "Before Launch" with one entry "Make". Remove that entry.
• Confirm with "OK"

For all tests:

If you want to remove this by default for all new test configurations (which might not be a terribly good idea, since then you got to allways build manually when running tests)

• Go to "Run" - "Edit Configurations..."
• Select "Defaults" in the Tree
• Select your Testframework (Junit or TestNG most probably)
• In the tab named "Configuration" there is a List "Before Launch" with one entry "Make". Remove that entry.
• Confirm with "OK"
