V8TestingScope is an abstraction class that encapsulates ScriptStateForTesting
etc. Would it be possible to add TrackExceptionState to V8TestingScope and use
it for payment tests?

Ideally, tests that require bindings should be written as follows:

TEST_F(...) {
  V8TestingScope scope;
  scope.xxx();  // You can get whatever you want (e.g., page, execution context,
script state etc) from the scope.
}

Done.
