Why not just do this in the constructor?

[benquan, 2013/01/25 00:55:31]

WhitelistManager's constructor checks chrome_switches, some of the testes in
this file needs to override switches before make an instance of
WhitelistManager.

[Ilya Sherman, 2013/01/25 01:22:40]

Hmm, fair enough.

[Ilya Sherman, 2013/01/24 22:01:55]

nit: Use C++-style casts rather than C-style casts, i.e. static_cast<size_t>(2).
 But in this specific case, you can just write 2U (U stands for "unsigned")
instead of 2.

[Ilya Sherman, 2013/01/24 22:01:55]

nit: ASSERT_EQ, since the test code below this will crash if there aren't enough
elements.

[Ilya Sherman, 2013/01/24 22:01:55]

Doesn't calling spec() on an invalid URL cause an assertion failure?

[benquan, 2013/01/25 00:55:31]

No, it doesn't, spec() returns an empty string.

In Debug mode, it will trigger a DCHECK:

What am I missing?

Oh, in my WhitelistManager::IsAutocheckoutEnabled(), I check url.is_empty()
first, it returns true for invalid urls, and it will not call spec().

Please add test cases for http://, and for no specified protocol.
