// How to add a new test:
// 1. Add a new value to the V8TestMode enumeration.
// 2. Add a method that implements the test in V8RendererTest.
// 3. Add a case for the new enumeration value in V8RendererTest::RunTest.
// 4. Add a line for the test in the "Define the tests" section at the bottom of
//    the file.
