IntelliUn IDEA中出现了JUnit测试版本

Question

During debugging the test code it hangs on the initialization phase. The latest message at the log is (before the debugging hangs):

2013-03-15 13:03:09:215 INFO [ : ] [main:ohdDialect] Using dialect: my.company.package.util.hibernate.HSQLDialect

Please consider the following factors which seems to impact the debugging:

• Test runs with @RunWith(SpringJUnit4ClassRunner.class)
• Test run on IntelliJ IDEA 12.0.4
• When tests run without debugging they works without any problems

What to do to debug the code?

Answer 1

Make sure you did not place a breakpoint on method signature instead of line of regular code. You can recognize such breakpoint also by 4 black dots inside red circle. They slow down debugging dramatically.

Answer 2

Try to remove all breakpoints and restart your Debug. Press Command+Shift+F8, then Command+A and press Del. This if for Mac.

Answer 3

It could easily be that you need to supply the test with more PermGen space.

Try using this in your configurations for that test:

-XX:MaxPermSize=300m 

If your tests aren't insanely huge (and they shouldn't be), this should be more than enough.
