> {{TestClient.testBasics()}} test checks error messages for the case of usage
> non-existent commands. But it contains block for help command which exists in
> yarn and supported by Drill (see {{CommandLineOptions.Command}} enum).
> This test shares the same {{TestContext}} instance for all the tests, but for
> some envs, {{TestContext.getOut()}} may return the result of the execution of
> previous block. So for some systems this test passes and for other may fail.
> The solution is to add {{TestContext.resetOutput()}} calls for every test
> block and remove block with {{help}} command since it contradicts test
> javadoc.
