What is this for?

[baxley, 2015/11/19 21:20:54]

Shouldn't be there, removed.

+    test.build('xctests.gyp', test.ALL)
+    test.built_file_must_exist('app_under_test.app/app_under_test')
+    test.built_file_must_exist('app_tests.xctest/app_tests')
+    if test.format == 'xcode':
+      test.built_file_must_exist('../../xctests.xcodeproj')

[justincohen, 2015/11/19 18:37:36]

Not sure what the value of checking this is for an xctests test?

[baxley, 2015/11/19 21:20:54]

Probably not needed, removed.

+    elif test.format == 'ninja':
+      test.built_file_must_exist('obj/AppTests/app_tests.AppTests.i386.o')
+      test.built_file_must_exist('obj/AppTests/app_tests.AppTests.x86_64.o')

[baxley, 2015/11/19 21:20:54]

Is there value in checking for the .o files to make sure things are compiled?
It's doable for the other formats, but those files are in much deeper
directories that may be dependent upon the configuration (Debug,
Debug-iphonesimulator, ...).

[justincohen, 2015/11/20 16:14:51]

I think there is.  There's always the chance something in Xcode changes and the
build does something unexpected.  Is it a problem to add this for xcode?

[baxley, 2015/11/20 21:33:47]

Okay, I added some code to look for the xcodebuild output. Let me know if you
have a cleaner way to find the fine.
