unittests are usually put into its own anonymous namespace

[sgurun-gerrit only, 2014/04/17 15:10:51]

Done.

[boliu, 2014/04/18 17:10:12]

Actually wrap the whole file in android_webview, then anonymous namespace. We
are not being very consistent here, so feel free to fix all our other unit test
files in a separate CL.

[sgurun-gerrit only, 2014/04/19 01:28:49]

That's something very loosely applied it seems -just checked 8 random unittest
files and only two of them has it. anyway, it makes sense to have the unit test
in the namespace, don't know why we are more strict about it.

Does the native object leak here?

Maybe the mock can keep going and actually call the callback.

[sgurun-gerrit only, 2014/04/18 01:44:55]

This does not apply anymore.

[boliu, 2014/04/16 02:57:46]

If mock uses ClientCertificateRequestCallback directly, can we continue the test
above to cover these two cases (instead of doing crazy jni here)

[sgurun-gerrit only, 2014/04/18 01:44:55]

not doing crazy jni anymore.
