// A helper class to create test web contents (tabs) for unit tests, without
// inheriting from RenderViewTestHarness. Can create web contents, and will
// clean up after itself upon destruction. Owns all created web contents.
// A few notes:
// - Works well allocated on the stack, because it should be destroyed before
//   associated browser context.
// - Doesn't play nice with web contents created any other way (because of
//   the implementation of RenderViewHostTestEnabler). But if you are creating
//   web contents already, what do you need this for? ;)
// TODO(devlin): The API is currently a bit sparse; there may need to be methods
// to, e.g., delete/close a web contents, access existing web contents, etc.
// These can be added as-needed.
