Example 1 with FetchValueResponse

use of webpiecesxxxxxpackage.service.FetchValueResponse in project webpieces by deanhiller.

the class TestLesson3Errors method testRemoteSystemDown.

/**
 * Tests a remote asynchronous system fails and a 500 error page is rendered
 */
@Test
public void testRemoteSystemDown() {
    XFuture<FetchValueResponse> future = new XFuture<FetchValueResponse>();
    mockRemote.addValueToReturn(future);
    HttpFullRequest req = TestLesson2Html.createRequest("/async");
    XFuture<HttpFullResponse> respFuture = http11Socket.send(req);
    Assert.assertFalse(respFuture.isDone());
    // notice that the thread returned but there is no response back to browser yet such that thread can do more work.
    // next, simulate remote system returning a value..
    future.completeExceptionally(new RuntimeException("complete future with exception"));
    ResponseWrapper response = ResponseExtract.waitResponseAndWrap(respFuture);
    response.assertStatusCode(KnownStatusCode.HTTP_500_INTERNAL_SVR_ERROR);
    response.assertContains("You encountered a Bug in our web software");
}

Example 2 with FetchValueResponse

use of webpiecesxxxxxpackage.service.FetchValueResponse in project webpieces by deanhiller.

the class TestLesson2Html method testAsyncControllerAndRemoteSystem.

/**
 * It is highly suggested you step through this test in debug mode to understand the description below...
 *
 * This is a single threaded test that actually allows the webserver thread to return back to the test before
 * the response comes.  (in production the thread would process other requests while waiting for remote system response).
 * Then the test simulates the response coming in from remote system and makes sure we send a response back
 * to the ResponseSender.  In implementations like this with a remote system, one can avoid holding threads up
 * and allow them to keep working while waiting for a response from the remote system.
