Should (can?) this target be in the test.gypi file?

[Eugene But (OOO till 7-30), 2016/05/16 23:39:58]

We don't have test.gypi in web. |test_mojo_bindings_mojom| target is used in
|ios_web_test_support| which is defined here.

So I guess the answer is no :)

[Jackie Quinn, 2016/05/17 23:07:06]

heh. okay. It just seems like all the testing stuff should live with the
unittests rather than in the main gyp file.

[Eugene But (OOO till 7-30), 2016/05/18 00:09:32]

Well not all the tests are unit tests. We have 2 other types of tests:
integration tests and EG tests. BTW in GN world there is only one .gn file per
directory.
