These can all be done more concisely if you pull them into functions that return
testing::AssertionResults. 

Also most of them sholud be EXPECT_TRUE not ASSERT_TRUE.

Something like

EXPECT_TRUE(IsString("[Function]", v8_object, "function"));

where

v8::AssertionResult IsString(const std::string& string, v8::Local<v8::Object>
object, const std::string& key) {
  if (...)
    return testing::AssertionFailure() << "failed cos..";
  rturn testing::AssertionSucces();
}

it's a nice pattern.

Done.
