Test case throws an "Uncaught AssertError"

[Vitali S.]

Hi,

I'm collecting my first experience with JsTestDriver in combination with WebStorm 5.
Now I reached my limit and need help.

Gateway_Test.prototype.test_sendRequest = function() {
   
    // get the gateway
    var gateway = Service.LogService.gateway;
    // register the LogService for logging
    gateway.registerService("LogService", Diagnostics.LogProvider);

    // Open the gateway
    gateway.onOpen(null);
    // Register gateway ready handler
    Gateway.GatewayProvider.registerReadyHandler(isReady);

    function isReady() {
        console.log("Gateway status: Ready!");
        sendMessage();
    }

    function sendMessage() {
        // Prepare and send message
        var msg = JSON.parse('{"service":"TestService"}');
        console.log("Prepared message before send to gateway: " + JSON.stringify(msg));
        // send the message and get the manipulated message back
        var outgoingMsg = gateway.sendRequest(msg);
        // provoke error
        outgoingMsg.callbackIdx = undefined;
        console.log("Manipulated message after send to gateway: " + JSON.stringify(outgoingMsg));
        // Expect that callbackIdx is not undefined
        assertNotUndefined("CallbackIdx Check", outgoingMsg.callbackIdx);
    }
};

The test case is passed (should fail) and the following messages are shown in the Chrome console:

1. Uncaught AssertError: CallbackIdx Check expected not undefined but was undefined runner.js:682
1. failrunner.js:682
2. assertNotUndefinedrunner.js:978
3. sendMessageGateway-test.js:82
4. isReadyGateway-test.js:70
5. fireReadyGateway.js:723
6. onReadyGateway.js:768
7. fireConnectionReadyGateway.js:219

Gateway(onClose): bridge closed: '[object CloseEvent]'. Diagnostics.js:40

Gateway(fireConnectionLost) Diagnostics.js:40

Gateway.GatewayProvider(onClose) Diagnostics.js:40

Gateway.GatewayProvider(fireClose)

1. Why does the test pass?
2. Why do I only see in the console an error?

Thanks

Vitali

Because your code is executing /after/ the test finishes.

To test asynchronous callbacks you need to use the
https://code.google.com/p/js-test-driver/wiki/AsyncTestCase.

Many thanks. I saw this page some times but did not know how to realize or adapt it to my code.
Now I got it.

Here is my working modified code:

var Gateway_sendRequest_Test = AsyncTestCase("Test the method sendReuest");
Gateway_sendRequest_Test.prototype.test_sendRequest = function(queue) {

    // get the gateway   
    var gateway = Service.LogService.gateway;

    queue.call('Step 1: open the gateway', function() {

       

        // register the LogService for logging
        gateway.registerService("LogService", Diagnostics.LogProvider);

        // Open the gateway
        gateway.onOpen(null);
        // Register gateway ready handler
        Gateway.GatewayProvider.registerReadyHandler(isReady);

        function isReady() {
            console.log("Gateway status: Ready!");

        };
    });

    queue.call('Step 1: send the request', function() {

        // Prepare and send message
        var msg = JSON.parse('{"service":"TestService"}');
        console.log("Prepared message before send to gateway: " + JSON.stringify(msg));
        // send the message and get the manipulated message back
        var outgoingMsg = gateway.sendRequest(msg);

        // Test manipulation to see what will happen on assert error

        outgoingMsg.callbackIdx = undefined;
        console.log("Manipulated message after send to gateway: " + JSON.stringify(outgoingMsg));
        // Expect that callbackIdx is not undefined
        assertNotUndefined("CallbackIdx Check", outgoingMsg.callbackIdx);

    });
};

This would make more sense:

    // get the gateway   
    var gateway = Service.LogService.gateway;

    var outgoingMsg;

    queue.call('Step 1: open the gateway', function() {

        // register the LogService for logging
        gateway.registerService("LogService", Diagnostics.LogProvider);

        // Open the gateway
        gateway.onOpen(null);
        // Register gateway ready handler
        Gateway.GatewayProvider.registerReadyHandler(isReady);

        function isReady() {
            console.log("Gateway status: Ready!");
            sendMessage();
        };
       
        function sendMessage() {

            // Prepare and send message
            var msg = JSON.parse('{"service":"TestService"}');
            console.log("Prepared message before send to gateway: " + JSON.stringify(msg));
            // send the message and get the manipulated message back

            outgoingMsg = gateway.sendRequest(msg);
            // Test manipulation to see what will happen on assert error

            outgoingMsg.callbackIdx = undefined;
            console.log("Manipulated message after send to gateway: " + JSON.stringify(outgoingMsg));

        }
    });

    queue.call('Step 1: send the request', function() {

        // Expect that callbackIdx is not undefined
        assertNotUndefined("CallbackIdx Check", outgoingMsg.callbackIdx);

    });
};
