### Question:
KieServerContainerVerifier { public static void main(String[] args) { boolean verified = main(args, System.out, System.err); if (!verified) { System.exit(1); } }  boolean verify(String releaseId); boolean verify(String groupId, String artifactId, String version); boolean verify(ReleaseId releaseId); boolean verify(KieContainer container); static void main(String[] args);  }### Answer:
@Test public void testMainEmpty() throws Exception { ByteArrayOutputStream err = new ByteArrayOutputStream(); boolean verified = KieServerContainerVerifier.main(new String[]{}, null, new PrintStream(err, true)); assertTrue(verified); assertEquals(KieServerContainerVerifier.USAGE, new String(err.toByteArray(), "UTF-8")); }
