LUCENE-7009: Add expectThrows utility to LuceneTestCase
> Add expectThrows utility to LuceneTestCase
> ------------------------------------------
>
> Key: LUCENE-7009

> Project: Lucene - Core
> Issue Type: Bug

> In junit5, a neat assertion method is added which makes testing expected
> failures a little more straightforward. The block of code that is
> expected to throw is passed in with a lambda expression, and the caught
> exception returned for inspection. The usage looks something like this:
> {code}
> IOException e = expectThrows(IOException.class, () -> {
> throw new IOException("some io error");
> });
> // assert stuff here about the exception
> {code}
> We should add this to LuceneTestCase until junit5 is available.
