There are no tests asserting that `Error parsing arguments [...]` is part of the error message.
Imo the test `testIllegalArgs` should be rewritten as follows: ``` @Test public void testThrowExceptionIfParameterIsNotPrefixed() { exception.expect(IllegalArgumentException.class); exception.expectMessage("Error parsing arguments '[a]' on 'a'. Please prefix keys with -- or -."); ParameterTool.fromArgs(new String[]{"a"}); } ``` [ Full content available at: https://github.com/apache/flink/pull/6737 ] This message was relayed via gitbox.apache.org for devnull@infra.apache.org
