I still think you can get rid of these. See more below.

Here you'll have something like

  expectEquals(expectedMsg, error);

Nit: should be indented four spaces (this is wrong in the functions above;
please fix those too).

Pass in an empty function which does nothing as the first argument, and the new
onSetLocalDescriptionError function as the second argument.
