""" !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%.
