ngMock.$exceptionHandlerProvider.mode()

Mode of operation, defaults to rethrow.

• log: Sometimes it is desirable to test that an error is thrown, for this case the log

  mode stores an array of errors in `$exceptionHandler.errors`, to allow later
  assertion of them. See assertEmpty() and
  reset()
  

• rethrow: If any errors are passed to the handler in tests, it typically means that there

  is a bug in the application or test, so this mock will make these tests fail.
  For any implementations that expect exceptions to be thrown, the `rethrow` mode
  will also maintain a log of thrown errors.
