Subject [jira] [Created] (SPARK-20234) Improve Framework for Basic ML Tests
Date Thu, 06 Apr 2017 00:11:41 GMT
Bryan Cutler created SPARK-20234:
------------------------------------

             Summary: Improve Framework for Basic ML Tests
                 Key: SPARK-20234
                 URL: https://issues.apache.org/jira/browse/SPARK-20234
             Project: Spark
          Issue Type: Improvement
          Components: ML, Tests
    Affects Versions: 2.1.0
            Reporter: Bryan Cutler


Recently, I came across a few simple ML bugs that should have been caught by basic checks,
but there was a lack of coverage because the existing checks are just tacked on to other tests
and easy to forget to add to new test suites.

I think it's worth spending some time to making these checks more standardized and easy to
bring into new test suites so they are not overlooked - possibly by using a trait.

The basic checks I'm referring to are:
* parameter checks
* uid checks
* model/estimator copies
* model/estimator persistence
