TODO(epoger): Create a command to update the expected results (in
|
||
|
|
self._output_dir_expected) when appropriate. For now, you should:
|
||
|
|
1. examine the results in self._output_dir_actual and make sure they are ok
|
||
|
|
2. rm -rf self._output_dir_expected
|
||
|
|
3. mv self._output_dir_actual self._output_dir_expected
|
||
|
|
Although, if you're using an SVN checkout, this will blow away .svn directories
|

|
|
within self._output_dir_expected, which wouldn't be good...
