[Grails] Speed up Integration test (Debug mode available)

1. Start up interactive mode in debug-mode
$ grails -debug

1	$ grails -debug

2. Connect from IDE

Connect remote from InteliJ
From menu Run -> Edit Configuration ->
then click + mark and select Remote

3. Start test
grails> test-app integration: classname -echoOut

1	grails> test-app integration: classname -echoOut

Run application in remote debug

Do run-app instead of test-app. It faster and stable(may be).

Without debug

Run interactive mode.

then run test.

It may be faster than run from IDE.
