> 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
