Unit Testing

All your application code should live in the application submodule of your Cougar project, so your unit tests should go there too.

Integration Testing

Manual

Depending on the interface/operation under test, you can use

• SoapUI (or similar SOAP service testing client)
• A browser (for RESCRIPT operations that only take query parameters)
• curl (for any RESCRIPT operation - see examples)
• An HTTP debugger/request builder such as Fiddler2

Automated

You may well want to do some sanity type integration testing, either during development or before a QA release, and you’ll want this to run as part of a CI build.

Black Box Testing

Testing using the Cougar Client

• Create a client Maven submodule (contains only IDD-generated client code, Spring assembly, and default properties).
• Add a test scope dependency on this from your launcher module

• Add an integration test class to the launcher module. Sample code follows:

  private static ExampleClient client; private static ClassPathXmlApplicationContext context; @BeforeClass public static void startCougar() throws InterruptedException { // Find and stipulate free ports int jettyPort = findFreePort(9001); int jmxPort = findFreePort(jettyPort + 1); int executionVenuePort = findFreePort(jmxPort + 1); int socketServerPort = findFreePort(executionVenuePort + 1); System.setProperty(“jetty.http.port”, “” + jettyPort); System.setProperty(“jmx.html.port”, “” + jmxPort); System.setProperty(“cougar.ev.port”, “” + executionVenuePort); System.setProperty(“cougar.socket.serverport”, “” + socketServerPort); // Set the endpoint to connect to System.setProperty(“cougar.client.rescript.remoteaddress”, “http://127.0.0.1:” jettyPort “/”); // Inconveniences (fix pending) System.setProperty(“betfair.config.host”, “/conf/”); // Start Cougar programmatically context = (ClassPathXmlApplicationContext) new CougarSpringCtxFactoryImpl().create(null); // Get the client (defined in the ‘client’ project itself) to test on client = (ExampleClient) context.getBean(“exampleClient”); } @AfterClass public static void stopCougar() throws InterruptedException { context.close(); } @Test public void testEcho() throws Exception { Echo actual = client.echo(“hello”); assertEquals(“hello”, actual.getEchoMessage()); } /** * Implementation pasted from Apache Mina project. */ private static boolean available(int port) { ServerSocket ss = null; DatagramSocket ds = null; try { ss = new ServerSocket(port); ss.setReuseAddress(true); ds = new DatagramSocket(port); ds.setReuseAddress(true); return true; } catch (IOException e) { // } finally { if (ds != null) { ds.close(); } if (ss != null) { try { ss.close(); } catch (IOException e) { // } } } return false; } private static int findFreePort(int start) { for (int port = start; port < start 100; port+) { if (available(port)) { return port; } } throw new RuntimeException(“Can’t find a free port…”); }

Testing from the Command Line

You could elect to test your service using curl (or alternative; examples of curl invocations can be found here), but this seems like a poor alternative to testing with a Java client.

White Box Testing

There exists a cougar-testing-services module, which can be included in your Cougar application by dropping its JAR into the lib directory of the deployed application. It has some white box testing features like cache management and log entry query. For those services that use it, the testing services module gets dropped into the relevant place as part of dev/QA deployment automation.

The operations listed by the interface (which you can see if you look at Cougar source, under the cougar-testing-service Maven module) are:

• refreshAllCaches
• refreshCache
• getIDD
• getLogEntries
• getLogEntriesByDateRange

There is no other documentation about this module, so if you need further details then please contact us.

You can always develop your own white box testing service to co-locate with the services you own if you desire.
