Build/Test: Add an intentionally failing test.

To ensure that Travis is sending messages to Slack, a test needs to fail, so here's a failing test.

This failing test (and no other failing tests) will be reverted once Travis confirms that it isn't failing to message Slack about failing tests.

See #40712.
