Catching exceptions in test code

[Kirk Lund]

Tests don't need to catch non-runtime exceptions and rethrow them. The
following:

    Awaitility.await().atMost(60, TimeUnit.SECONDS).untilAsserted(() -> {
      try {
        assertEquals(size, query.findPages().size());
      } catch (LuceneQueryException e) {
        throw new RuntimeException(e);
      }
    });

Can be simplified to:

    Awaitility.await().atMost(60, TimeUnit.SECONDS).untilAsserted(() -> {
      assertEquals(size, query.findPages().size());
    });

And even better would be to use AssertJ and make it a lambda with some
static imports:

   await().atMost(60,SECONDS).untilAsserted(() ->
assertThat(query.findPages()).hasSize(size));
