> I recently added some test code through SOLR-12427 which used the following test anti-pattern:
> {code}
> try {
>     actionExpectedToThrowException();
>     fail("I expected this to throw an exception, but it didn't");
> catch (Exception e) {
>     assertOnThrownException(e);
> }
> {code}
> Hoss (rightfully) objected that this should instead be written using the formulation
below, which is clearer and more concise.
> {code}
> SolrException e = expectThrows(() -> {...});
> {code}
> We should remove many of these older formulations where it makes sense.  Many of them
were written before {{expectThrows}} was introduced, and having the old style assertions around
makes it easier for them to continue creeping in.
