> This doesn't need to be part of each {{PipelineRunner}} implementation if it 
> goes through the {{PipelineResult}} APIs. The assertion can be of the form 
> that if the Pipeline is finished, then the number of successful assertions is 
> equal to the total number of assertions.
> Suggested solution:
> For runners which support metrics, use the counters for successful/failed 
> assertions and compare them to expected number of assertions.
> For runners which do not support metrics consider implementing a fallback 
> solution:
> {{PAssert}} will write to temp files, which will be placed in the test's 
> {{tempLocation}} ({{file}} in local mode, {{gs/hdfs}} in cluster mode). These 
> temp files' names will include a UUID generated for each test, this UUID will 
> be accessible to {{PAssert}} or the text sink.
> Successful assertion count and failed assertion count + exceptions will be 
> written to text files which will then be accessible to {{TestPipeline}} to 
> assert on.
