Boolean flags stink for readability. Consider adding a ContextType enum. Current
value: frame, content script. In the future there could also be "worker".

Done.

I'm not sure it's entirely right though. In ExtensionDispatcher where this is
created, there are more than just content scripts and frames, right? Currently
frame -> "other".

[Aaron Boodman, 2012/02/16 02:01:53]

That's a good point. I'm not sure if this is called for workers. You can rename
it to other if it pleases you. Or NotContentScript :).

 
   context_set.Add(context);
   EXPECT_EQ(1u, context_set.GetAll().count(context));
   EXPECT_EQ(context, context_set.GetByV8Context(context->v8_context()));
 
   // Adding the same item multiple times should be OK and deduped.
   context_set.Add(context);
   EXPECT_EQ(1u, context_set.GetAll().count(context));
 
   // GetAll() returns a copy so removing from one should not remove from others.
   ChromeV8ContextSet::ContextSet set_copy = context_set.GetAll();
   EXPECT_EQ(1u, set_copy.count(context));
 
   context_set.Remove(context);
   EXPECT_EQ(0, context_set.size());
   EXPECT_FALSE(context_set.GetByV8Context(context->v8_context()));
   EXPECT_EQ(1u, set_copy.size());
 
   // After removal, the context should be marked for destruction.
   EXPECT_FALSE(context->web_frame());
 
   // Run loop to do the actual deletion.
   loop.RunAllPending();
