Hippie

Monitors external service endpoints from integration tests by automatically sending Nagios passive service checks.

Example

If you are using JUnit v4.7 or later, you can use the JUnit Rule API to
write integration tests in the following style:


public class IntegrationSmokeTests {
        private String nscaServer = "nagios.box";

        private String nscaPassword = "password";

        private int nscaPort = 5667;

        private int nscaConnectionTimeout = 5000;  // ms

        private int nscaResponseTimeout = 15000;  // ms

        private NagiosNotifier notifier = new NagiosNotifier(nscaServer,
                nscaPassword, nscaPort, nscaConnectionTimeout,
                nscaResponseTimeout);

        private String serviceHost = "service.box";

        @Rule ServiceMonitor monitor = new ServiceMonitor(serviceHost,
                notifier);

        @Test
        @MonitorsService(name = "AwesomeService")
        public void awesomeServiceShouldBeAvailable() throws Exception {
                final Service awesome = new AwesomeService();

                smokeTest(awesome);

                assertEquals(Service.AVAILABLE, awesome.getStatus());
                assertEquals(Service.CORRECT, awesome.getResponse());
        }

        @Test
        @MonitorsService(name = "Google", onHost = "google.com",
            failureMessage = "Google should never be down, so something must be terribly wrong!")
        public void googleShouldNeverBeDown() throws Exception {
                final Service google = new GoogleService();

                assertEquals(Service.AVAILABLE, google.ping());
        }

        @Ignore
        @Test
        @MonitorsService(name = "UndocumentedService",
            ignoredMessage = "ignoring until we finish reverse-engineering this undocumented API")
        public void awesomeServiceShouldBeAvailable() throws Exception {
                final Service undocumented = new UndocumentedService();

                // TODO: figure out the correct order of these calls:
                /*
                undocumented.setListener(Environments.INTEGRATION_TEST);
                undocumented.initialize();
                final Token token = undocumented.getRequestToken();
                final Service.Response response = undocumented.invoke(token);
                */

                assertEquals(Service.CORRECT, response.validate());
        }

        @Test
        @MonitorsService(name = "UnstableService",
            successMessage = "I can't believe it actually worked!")
        public void awesomeServiceShouldBeAvailable() throws Exception {
                final Service unstable = new UnstableService();

                final Response response = unstable.invoke();

                assertEquals(Service.AVAILABLE, response.getStatus());
        }

        @Test
        @MonitorsService(name = "UberService",
            failureMessage = "can't connect!",
            ignoredMessage = "fiddling with something",
            successMessage = "all systems are go!")
        public void awesomeServiceShouldBeAvailable() throws Exception {
                final Service uber = new UberService();

                smokeTest(uber);

                assertEquals(Service.AVAILABLE, uber.getStatus());
                assertEquals(Service.CORRECT, uber.getResponse());
        }
}

If you are using JUnit v4.6 or earlier then you must use the
hippie runner, instead (which also works with JUnit v4.7+,
but is not preferred):


@RunWith(NagiosAwareRunner.class)
public class IntegrationSmokeTests {
        static {
                // Ideally, you would set these properties via your
                // build tool (i.e. Ant, Maven, etc.), in your IDE, or
                // at the command line.
                System.setProperty("hippie.nsca.server", "localhost");
                System.setProperty("hippie.nsca.password", "ABC123");

                // Optional JVM/System properties you can also set if
                // you need to override the defaults:
                // - hippie.nsca.port (default: 5667)
                // - hippie.nsca.timeout.connection (default: 5000 ms)
                // - hippie.nsca.timeout.response (default: 15000 ms)
        }

        @Test
        @MonitorsService(name = "AwesomeService", onHost = "qa.env")
        public void awesomeServiceShouldBeAvailable() throws Exception {
                final Service awesome = new AwesomeService();

                smokeTest(awesome);

                assertEquals(Service.AVAILABLE, awesome.getStatus());
                assertEquals(Service.CORRECT, awesome.getResponse());
        }

        @Test
        @MonitorsService(name = "Google", onHost = "google.com",
            failureMessage = "Google should never be down, so something must be terribly wrong!")
        public void googleShouldNeverBeDown() throws Exception {
                final Service google = new GoogleService();

                assertEquals(Service.AVAILABLE, google.ping());
        }

        @Ignore
        @Test
        @MonitorsService(name = "UndocumentedService", onHost = "dev",
            ignoredMessage = "ignoring until we finish reverse-engineering this undocumented API")
        public void awesomeServiceShouldBeAvailable() throws Exception {
                final Service undocumented = new UndocumentedService();

                // TODO: figure out the correct order of these calls:
                /*
                undocumented.setListener(Environments.INTEGRATION_TEST);
                undocumented.initialize();
                final Token token = undocumented.getRequestToken();
                final Service.Response response = undocumented.invoke(token);
                */

                assertEquals(Service.CORRECT, response.validate());
        }

        @Test
        @MonitorsService(name = "UnstableService", onHost = "test",
            successMessage = "I can't believe it actually worked!")
        public void awesomeServiceShouldBeAvailable() throws Exception {
                final Service unstable = new UnstableService();

                final Response response = unstable.invoke();

                assertEquals(Service.AVAILABLE, response.getStatus());
        }

        @Test
        @MonitorsService(name = "UberService", onHost = "production.env",
            failureMessage = "can't connect!",
            ignoredMessage = "fiddling with something",
            successMessage = "all systems are go!")
        public void awesomeServiceShouldBeAvailable() throws Exception {
                final Service uber = new UberService();

                smokeTest(uber);

                assertEquals(Service.AVAILABLE, uber.getStatus());
                assertEquals(Service.CORRECT, uber.getResponse());
        }
}
