Don't you need the codecs/test/ in the path? Maybe it's not needed...

Without that prefix, 'git cl presubmit' passes, but with the prefix I get
errors:

I see. It doesn't take the path into account then (I didn't look into the
details on how the check is implemented).

+    "+base/android",
+    "+webrtc/sdk",
+  ],
+  "videoprocessor_integrationtest\.h": [

[kjellander_webrtc, 2017/02/14 11:00:15]

I'd recommend ".*test\.cc" instead. It would avoid the extra hassle when adding
more tests in the future.

[brandtr, 2017/02/14 14:22:37]

Done. In order to get it to pass, I had to do ".*test\.h" however. Do you think
I should add ".*test\.cc" as well, even though it's not strictly needed here?

(I tried to add ".*test\.{cc,h}", to no avail.)

[kjellander_webrtc, 2017/02/14 14:30:13]

Hmm, 
By looking at other examples
(https://cs.chromium.org/chromium/src/apps/DEPS?rcl=ea69b8739b1bf1a220ea541cca...)
it seems this should work at least:
"(.*test\.cc|.*test\.h)"

[brandtr, 2017/02/14 14:34:20]

It did. Thanks!
