@Test
public void testPushAndBindServices() throws Exception {
    //This test fails occasionally because service binding is 'unreliable'. Had a long discussion
    // with Ben Hale. The gist is errors happen and should be expected in distributed world.
    //They are coming from 'AppDirect' which manages the services. The errors are mediated through cloudfoundry
    // which doesn't knwow how it should handle them. So it passed the buck onto the its callers.
    //In this case.... cf-java-client which does the same thing and passes them to us.
    //All the reasons why they can't handle these errors also apply to us, which means that
    //the operation is simply unreliable and so failure is an expected outcome even when everything
    //works correctly.
    //To avoid this test case from failing too often we retry it a few times.
    RetryUtil.retryTimes("testPushAndBindServices", 4, () -> {

        String service1 = services.createTestService();
        String service2 = services.createTestService();
        String service3 = services.createTestService(); //An extra unused service (makes this a better test).

        String appName = appHarness.randomAppName();
        CFPushArguments params = new CFPushArguments();
        params.setAppName(appName);// ww  w . j  a  v  a  2s  .  co m
