Add Googletest assertion support for CGRect and NSRect

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Daniel Bates]

Make EXPECT_EQ() and other Googletest assertions work with CGRect and NSRect types. This makes it easy to write tests using these types and gives pretty output like this:

/Volumes/.../Tools/TestWebKitAPI/Tests/WebKitCocoa/DocumentEditingContext.mm:231
Expected equality of these values:
  CGRectMake(138, 0, 23, 24)
    Which is: (origin = (x = 138, y = 0), size = (width = 23, height = 24))
  rects.firstObject.CGRectValue
    Which is: (origin = (x = 96, y = 0), size = (width = 16, height = 17))

Probably could use a template to avoid duplicating this code.... I'm not really bothered by duplicating this code.

makeString() would make this more elegant

Maybe, but it would be a tiny bit less efficient because the resulting WTF::String needs to be converted (implicitly or explicitly) to a C-string at the end to insert into the stream.
