Does it matter that we're appending all these switches after the command line is
set up and we initialize everything?

[Rahul Chaturvedi, 2016/09/07 20:13:23]

Nope. These aren't checked at startup, they are checked during the call to the
API.

"Basic" doesn't really describe what this tests.

[Rahul Chaturvedi, 2016/09/07 20:13:23]

It is better than "ChromeOSInfoPrivateTest", which it was before.
When I read "Basic", to me it usually means basic functionality, which is
exactly what this test does.

If you can suggest a better name, I'll gladly change it to that.

[Devlin, 2016/09/07 20:40:29]

Looks like we just test get() and set() in that test, so how about
TestGetAndSet?

[Rahul Chaturvedi, 2016/09/07 20:45:01]

Done.

[Devlin, 2016/09/07 16:12:28]

What about public session?

[Devlin, 2016/09/07 16:12:28]

Browser tests are pretty slow.  If we can adjust the session type on the fly
like this (see also comment at l37), can we run all these tests in a single
test?

[Rahul Chaturvedi, 2016/09/07 20:13:23]

I have no good way to test that now. I will add tests for it later, once this is
merged in to M54.

[Rahul Chaturvedi, 2016/09/07 20:13:23]

Calling RunPlatformAppTestWithArg multiple times on the same app from within the
same test seems to crash.

[Devlin, 2016/09/07 20:23:27]

That's because RunPlatformAppTest loads the extension, which is already loaded
here.  All you want to do is actually run the test (i.e. navigate to the page
and wait for a result).

[Devlin, 2016/09/07 20:38:50]

As discussed offline, we can leave this as-is for now.  Please add a TODO to
investigate merging these tests.

[Rahul Chaturvedi, 2016/09/07 20:45:01]

Done.
