""" !Changing this line will break Test_findfile.test_found!

Non-gui unit tests for grep.GrepDialog methods.
|

dummy_command calls grep_it calls findfiles.
|
||
|
|
An exception raised in one method will fail callers.
|

Otherwise, tests are mostly independent.

Currently only test grep_it, coverage 51%.
