It'll be nice to have better comment and naming. E.g. kTest will be registered.

About naming: kClear is close to ClearKey. And it's unclear that kTest will be
registered. I don't have a good suggestion now. How about kUnregistered,
kUnsupported, kBad...? Or kTestSupported and kTestUnsupported?

Also, what's the relation between these and the kUnrecognized on line 202? More
comments would help.

kBarAudioCodecs?

[ddorwin, 2013/09/12 22:35:40]

It's the codecs for the Foo container. It makes more sense at line 74. I fixed
48-49 to match.

Also, based on feedback below, I changed the codec names to match the container
name. It's weird, but easier to understand since these aren't real types.

When should we use baraudio_codec_ and when should we use kFooAudioCodecs? It's
a bit confusing to me.

[ddorwin, 2013/09/12 22:35:40]

kFooAudioCodecs is the codecs supported by that container. These are used for
individual tests.

I could name it kRegisteredFooAudioCodecs, but that would cause extra lines.

This pattern is used in a lot of times, worth wrapping it into a helper
function?

EXPECT_TRUE(VerifyKeySystemNameForUMA("ClearKey", kClearKey));

or just VerifyUMAName()

[ddorwin, 2013/09/12 22:35:40]

I want to keep the comparison here for failure readability, but I created a
helper for WebString conversion and switched to EXPECT_EQ.

 
   // Not yet out from behind the vendor prefix.
   EXPECT_FALSE(IsConcreteSupportedKeySystem("org.w3.clearkey"));

[xhwang, 2013/09/11 20:38:55]

I see both 

IsConcreteSupportedKeySystem("org.w3.clearkey")

and 

IsConcreteSupportedKeySystem(WebString::fromUTF8(kClearKey))

Shall we consolidate them? Ideally it'll be nice is we can hide the
WebString::fromUTF8() part. It really doesn't add any value to the test but
noise.

[ddorwin, 2013/09/12 22:35:40]

The difference was unprefixed vs. prefixed. I've named constants to make this
