TODO(epoger): Create a command to update the expected results (in
|
|
OUTPUT_DIR_EXPECTED) when appropriate. For now, you should:
|
|
1. examine the results in OUTPUT_DIR_ACTUAL and make sure they are ok
|
|
2. rm -rf OUTPUT_DIR_EXPECTED
|
|
3. mv OUTPUT_DIR_ACTUAL OUTPUT_DIR_EXPECTED
|
|
Although, if you're using an SVN checkout, this will blow away .svn directories
|
|
within OUTPUT_DIR_EXPECTED, which wouldn't be good...
