allow stubbing & mocking by RegExp or Matcher

As a convenience allow stubbing and mocking multiple methods or properties by providing a RegExp or Matcher as the method name.

// using a RegExp
stub(permissions).method(/can(Edit|Show|Delete)/).returns(true);

// using a Matcher
var eventDispatcherMethods:Array = ['addEventListener', 'dispatchEvent', 'hasEventListener', 'removeEventListener', 'willTrigger'];
stub(permissions).method(inArray(eventDispatcherMethods)).anyArgs().pass();

channelset.login

Hi Drew

Is there anyway to mock a channelset.login and logout? I have the following code in my delegate called from my controller, which I would like to confirm works. I tried Brian LeGross's RPCStubs, but he confirmed that he has not yet implemented channelsets, so just wondering if this is something you deal with?

Thanks
Des

Controller

public class LoginController extends AbstractController
{
[Inject] // Wire in the model
public var loginModel:LoginModel;

    [Inject]    // Wire in the delegate for remote calls
    public var loginDelegate:LoginDelegate;

    [Dispatcher]    // Allows this class to dispatch events.
    public var eventDispatcher:IEventDispatcher;

    public function login():void {
        // Handle successful login.
        var loginResultEvent:Function = function(event:ResultEvent ):void  {
            eventDispatcher.dispatchEvent( new AuthenticationEvent (AuthenticationEvent.LOGGEDIN));
        }

        // Handle login failure.
        var loginFaultEvent:Function = function(event:FaultEvent):void {
            this.eventDispatcher.dispatchEvent(new AuthenticationEvent (AuthenticationEvent.LOGIN_FAIL));
        }
        // Log into the Remote server channelset login
        executeServiceCall(loginDelegate.login (loginModel.username,loginModel.password), loginResultEvent, loginFaultEvent);
    }

}

Delegate

public class LoginDelegate
{

    private var channelSet:ChannelSet;

    public function login(username:String, password:String):AsyncToken
    {
        channelSet = ServerConfig.getChannelSet(authenticationService.destination);
        return channelSet.login(username, password);
    }

}

verify() needs more descriptive errors

for example:

verify(instance).method('notCalled').once();

currently fails with the message: Error: no invocations as METHOD, when it really should include the name of the method, the type of instance, and its mockolate name if any.

Allow mocking of Proxy subclasses

Proxy subclasses like WebService are used with dynamic methods that do not appear in the public namespace of describeType. These dynamic method invocations should be forwarded to Mockolate for mocking and stubbing. Implementation will be similar to the MockolateProxy.

MockolateRule should verify instances created with strict() and nice()

When using the MockolateRule it should hook into strict() and nice() and verify instances created with those in VerifyMockInstance.

FlexUnit 4.1 CIListener doesn't like mockolate?

Hi Drew

I have written a test case which relies heavily on mockolate and have all my tests running and passing through the FlexUnit view in FlashBuilder4.5.

I also have an ant task that executes all my flex unit tests via a CIListener and generates a report. Weird thing is, when I run the tests through ant (and eventually on my build server) the ones using mockolate error ....even though they were working in Flashbuilder.

I have made sure FB and ant are both using the same version of Flex Unit 4.1 RC2.

The two errors I seem to be getting when running the ant script are:

Error #1065: Variable org.hamcrest.collection::emptyArray is not defined.

ReferenceError: Error #1065: Variable org.hamcrest.collection::emptyArray is not defined.

This is my test case for a RL mediator, the actual mediator and view are both really simple, but let me know if you need to see the source code.

public class NavButtonsMediatorTest

}

I could of course be massively mis-using mockolate or flex unit so any guidance you could offer will be much appreciated.

Unmet Expectation but not sure why

Hi,

Am getting the below exception when trying to mock a class. I'm not able to work out why I'm not meeting the expectation? time.execute() calls the mocks makeRequest() method.

Any help is gratefully appreciated.

The test case is:

[Test(async)]
public function testCallToGetTimeReturnsDateObject() : void {
var dvbService:DVBIPBridgeService = nice(DVBIPBridgeService);
record(dvbService);
expect(dvbService.makeRequest(expectArg({command : "time"})));
replay(dvbService);

    var time : TimeCommand = new TimeCommand(dvbService);

    time.execute();

    verify(dvbService);
}

The code under test is:

public class TimeCommand extends EventDispatcher {
static const REQUEST_SUCCESS:String = "onRequestSuccess";
private var _service:DVBIPBridgeService;

public function TimeCommand(service : DVBIPBridgeService) {
    _service = service;
    _service.addEventListener(DVBIPBridgeService.REQUEST_COMPLETE, onRequestComplete);
}

public function execute():void {
    _service.makeRequest({command : "time"});
}

private function onRequestComplete(event:DVBIPBridgeServiceSuccessEvent):void {
    var date : Date = new Date();
    date.setTime(event.data.time * 1000);
    dispatchEvent(new TimeCommandSuccess(REQUEST_SUCCESS, date));
}

}

HttpService mocking problem - and solution

Drew,

I've just started using Mockolate, which seems to me to be the most fully featured Flex mocking framework out there, and I have been wrestling with getting a mock HttpService working.

Here's the consumer of the service:

public class LoadEmployeesDelegate 
{
    private var responder : IResponder;
    public var service : HTTPService;

    public function LoadEmployeesDelegate( responder : IResponder ) 
    {
        this.service = new HTTPService();
        this.service.url="assets/Employees.xml";
        this.responder = responder;
    }

    public function loadEmployeesService() : void 
    {
        var token:AsyncToken = service.send();
        token.addResponder( responder );
    }
}

The first approach I used was:

[Rule]
public var rule:MockolateRule = new MockolateRule();

[Mock]
public var httpService : HTTPService;

...
// no send parameters so set to null
// don't care about the fault details so set blank
mock(httpService).asHTTPService().send(null).fault("","","");

This didn't work because it failed to return an AsyncToken :(

I then tried the following which did work :)

var token:AsyncToken = new AsyncToken();
var faultEvent:FaultEvent = new FaultEvent(FaultEvent.FAULT, false, false, new Fault("", "", ""), token);
mock(httpService).method("send").returns(token).answers(new FaultAnswer(token, faultEvent));

My question is, why did the first example fail, and what is the purpose of the asHTTPService() method. Is there any way to refactor the failing example so that it returns the AsyncToken without the verbose setup of the second?

Many thanks,

Murray

HTTPServiceDecorator not verifying send parameters

Hi,

I've written the following unit test following the example in StubbingHttpService.as file. When I run it it passes which it shouldn't because the HTTPService.send() method isn't being called within the actual code. My expectation is for an ExpectionError to be thrown.

What am I doing wrong?

[RunWith("mockolate.runner.MockolateRunner")]
public class DVBIPBridgeServiceTest {

[Mock]
public var httpService : HTTPService;

[Test(async)]
public function testExecuteRequestReturnsJSONData() : void {
    var expectedData : String = "[\"OK\", \"TIME\", {\"localtime\": [2010, 9, 21, 11, 22, 23, 1, 264, 1], \"asctime\": \"Tue Sep 21 11:22:23 2010\", \"time\": 1285064543.01}]";

    mock(httpService).asHTTPService().method("GET").send(hasProperties({command : "time"})).result(expectedData);

    var service : DVBIPBridgeService = new DVBIPBridgeService(httpService);

    Async.handleEvent(this, service, DVBIPBridgeService.REQUEST_COMPLETE, function(event:Event,data:Object) : void {
        var requestData : Object = service.getData();
        assertThat(requestData[1], equalTo("TIME"));
        assertThat(requestData.localtime.time, equalTo(1285064543.01));
    });

    service.makeRequest({command : "time"});

}

}
}

An interesting use case - iterable.

So here's a requirement for a matcher, and in the first, would like your feedback.

I often accept Object as a parameter type when i actually mean IIterable - However there is no IIterable interface in as3 that does what i need, which is, require a type that can be iterated over with for each (.. in ...)

A matcher for Iterable that simply caught exceptions on for each (var item:Object in parameterUnderTest) would be very handy for letting my tests show the real intent, even if my parameter type cant.

eg:

stub(stubTarget).method("addItems").args(Iterable())

Incorrect count in test spy

I tried to use spy test but I had problems when the test checked how many the methos was executed.

Example:

contextPart = nice(IXMLAContextPart);
_xmlaPart.context = contextPart;
mock(contextPart).getter("nodeDepth").returns(1);
mock(contextPart).method("useRootNode").returns(true);
mock(contextPart).method("template").returns();
mock(contextPart).method("validate").args(anyOf(equalTo("var_1"),equalTo("var_2"))).returns(true);
mock(contextPart).method("validate").args("NO_VALIDATE_AND_DONT_ADD").returns(false);

_xmlaPart.add("var_1", "HOLA");
_xmlaPart.add("var_2", "HOLA2");
var xml:XML = _xmlaPart.generate();

assertThat(contextPart, received().method('template').noArgs().times(1)); //not works. If I use 2 times, the test past... but only once is executed inside generate() funcion
assertThat(contextPart, received().method("useRootNode").noArgs().times(2)); //not works. Same of previous.
assertThat(contextPart, received().method("useRootNode").twice()); //not work
assertThat(contextPart, received().getter("nodeDepth").times(1)); //works fine
assertThat(contextPart, received().method('validate').args(anything()).times(2)); //works fine

generate() function use internaly "nodeDepth", "useRootNode" and "template" once each.

Event dispatches twice

Trying to mock ITransmitter interface, wich is derived from IEventDispatcher and dispatch event. The problem is that event dispatches twice. Here is the example:

var events: Array = new Array();
var t: IEventDispatcher = nice(ITransmitter);
stub(t).asEventDispatcher();
t.addEventListener(UploadEvent.COMPLETE, function(e: UploadEvent): void {
    events.push(e);
});
t.dispatchEvent(new UploadEvent(UploadEvent.COMPLETE));

At the end, 'events' array contains 2 objects, but should only one.

Explicitly define namespaces to proxy

In order to work around the brokenness of the flash.utils.describeType() not reporting final on method, properties, variables, require the user to explicitly define which namespaces they would like to proxy.

Suggested APIs:

Raw API, using namespace references.

prepareWithNamespaces(ClassToPrepare, [ flash_proxy, mx_internal ]);

Metadata API, using fully qualified namespace names.

[Mock(namespaces="flash.utils.flash_proxy,mx.core.mx_internal")]
public var doodad:ClassToPrepare;

Publish ASDocs

Publish Mockolate ASDocs to http://mockolate.org/

allow verify() with inline invocations

mirror the inline invocations allowed for expect() with the verify() / test spy functionality.

something like:

verify(instance);
spy(instance.method(arg1, argN)).once();
spy(instance.method(spyArg(), spyArg()).once();

Function.apply(this, parameters)

Attempting to call a method on the proxy by using Function.apply() fails as the proxy thinks it is a property invocation not a method invocation. Mockolate should return a function reference for the property getter if a method exists for the same name as the property.

Example use case:

public class LoggerProxy implements ILogger
{
    private var _logger:ILogger;

    public function set logger(value:ILogger):void 
    {
        _logger = value;
    }

    public function get debugEnabled():Boolean 
    {
        return _logger ? _logger.debugEnabled : false;
    }

    public function debug(message:String, ... parameters):void
    {
        if (debugEnabled)
            _logger.debug.apply(_logger, [ message ].concat(parameters));
    }   
}

default expected invocation count for mock() is not working.

Conditional at MockingCouverture#expectationAdded() line 862 is wrong. It should be checking _expectationsAsMocks.

Workaround, specify .once() or atLeast(1) for the expectation.

Allow access to recorded Invocations

To aid diagnosis of invocation and expectation errors provide an API to access the invocations that were recorded by a Mockolate instance.

Classes in default package are not proxied correctly.

Appears to be a bug in FLoxy.

will not work:

package {
    class Anything {
        public function invoke(args:Array):void {
        }
    }
}

Feature Request: Never

[Test(given="with an empty list, a Proxy list, and list is observed",
    it="does not call the proxy manager")]
public function it():void {
    withAnEmptyList();
    withAProxyList();
    withListObserved();

    verify(proxyList).method(PROXY_LIST_ADD).atMost(NEVER);
    verify(proxyList).method(PROXY_LIST_REMOVE).atMost(NEVER);
    verify(proxyList).method(PROXY_LIST_RESET).atMost(NEVER);
    verify(proxyList).method(PROXY_LIST_DISPOSE).atMost(NEVER);
}

method().never() would be tidier.

resultEvent value not mocking properly

Drew

I think I found another possible bug? I am mocking a delegate to return a resultEvent. Inside the code for the Controller, the delegate result returned is correct, but as soon as I exit the controller and come back to the test, the value is not carried through.

This test below fails, with the last Assert returning false, instead of the required true which was set on the mock. When I debug it in the Controller, the value is being set correctly on the model as per the mock, but as soon as I exit the controller, the value is lost.

I tried to catch the ResultEvent.RESULT to see if that is where the value is set, but no luck

Async.handleEvent(this, fixture.eventDispatcher, ResultEvent.RESULT,check,500,null,noEventFired);

Any ideas what I am missing here?

Thanks
Des

Here is an example of it:

Test

{
[Test(async)]
public function checkUsernameTest_user_exists():void
{
// Create the authenticationEvent the Presenter would have sent
authenticationEvent = new AuthenticationEvent(AuthenticationEvent.CHECK_USERNAME);
authenticationEvent.username = testUsername;

        var result:Object = true;       // User does exist
        var token:AsyncToken = new AsyncToken();
        var resultEvent:ResultEvent = new ResultEvent(ResultEvent.RESULT, false, false, result, token);

        // Mock the delegate to return an AsyncToken
        mock(loginDelegateMock).method("checkUsernameExists").args(authenticationEvent.username).returns(token).answers(new ResultAnswer(token, resultEvent));

        // Assert that if you receive "false" the USERNAME_EXISTS event is fired
        Async.proceedOnEvent(this,fixture.eventDispatcher,AuthenticationEvent.USERNAME_EXISTS,500,noEventFired);

        // Make a call to the backend to check if this username exists
        fixture.checkUsername(authenticationEvent);

        Assert.assertEquals("Assert that the loginModel.usernameExists has changed in Model:", true, fixture.loginModel.usernameExists);

}
}

Controller

{
[Mediate(event="AuthenticationEvent.CHECK_USERNAME")]
public function checkUsername(authenticationEvent:AuthenticationEvent):void {

        var checkUsernameResultEvent:Function = function (resultEvent:ResultEvent):void
        {
            // Assign the result to the model
            loginModel.usernameExists = resultEvent.result as Boolean;
        }

        var checkUsernameFaultEvent:Function = function (faultEvent:FaultEvent):void
        {
            // handle fault
        }

executeServiceCall(loginDelegate.checkUsernameExists(authenticationEvent.username),
checkUsernameResultEvent, checkUsernameFaultEvent);
}
}

Delegate (being mocked)

{
public function checkUsernameExists(username:String):AsyncToken
{
return authenticationService.isValidUser(username);
}
}

Model

{
public class LoginModel{
public var username:String = "";
public var password:String = "";
public var usernameExists:Boolean;
}
}

Allow constructor args for mocks created by MockolateRule

For vars marked with [Mock] if there is a constructorArgs attribute, try calling resolving and calling a function with the same name on the current test case to get the array of parameters to pass to the constructor.

[Mock(constructorArgs="exampleArgs")]
public var example:Example;
public function exampleArgs():Array { return ["Example", true, 3]; }

Add FlexUnit 4.1 requirement for MockolateRule to docs

MockolateRule required FlexUnit 4.1+, add a mention to the gotchas section and where MockolateRule is first mentioned.

update verify() syntax to include getter() and setter()

Better error handling for Runner/Rule

Report on vars with [Mock] must be public.
Preparing an empty Array of classes throws an error. Don't do that.

Allow mocking of namespaced methods and properties

Examples include mocking the Proxy flash_proxy methods, mx_internal etc.

Will require changes to FLemit, FLoxy.

Preparing and Creating Mockolates from interfaces?

I tried to create Mockolate form interface with:

[Rule]
public var mocks:MockolateRule = new MockolateRule();

[Mock]
public var mockIExample:IExample;

but I got this error:

Illegal override of  IExample

where IExample is an interface.

deprecate verifying with property()

Log warnings for classes with public vars

By default make Mockolate log warnings for situations where it cannot create appropriate proxy methods.
For example log warnings for each public var field in a class when passed to prepare().

MockolateRule should provide mock(), stub(), verify()

To save a few imports and make syntax completion a bit nicer, the MockolateRule should provide mock(), stub() and verify().

[Rule]
public var mocks:MockolateRule = new MockolateRule();

[Mock]
public var flavour:Flavour;

[Test]
public function example():void 
{
    mocks.mock(flavour).method("combine").args(Flavour).once();
    ...
    mocks.verify(flavour);
}

test using mockolate 10.0 and flexunit 4.1 rc2 says proxy isn't prepared

Mocking FileReference browse & load methods

Drew

Another one for you ;-)

I have a function that loads a local file and then processes is. I want to mock the FileReference browse() and load() functions, so I can test my file logic. Been playing with mocks, but I cannot seem to get what I need to do from the source. The three steps I need to complete are:

Mock the internal FileReference
Mock the AddEventListener to "progressHandler"
Dispatch the Event.COMPLETE event on the filereference object

Is there a way I can do this?

The function I am trying to mock:

public function addRateSheet():void
{
var loadFile:Function = function(event:Event):void
{
fileReference.load(); // NO NEED TO MOCK THIS FUNCTION, BUT NEED TO CALL THE EVENT ON THE fileReference
};
// Add Event listerners for the upload sequence
fileReference.addEventListener(Event.SELECT, loadFile); // NO NEED TO MOCK THIS
fileReference.addEventListener(Event.COMPLETE, fileLoadCompleteHandler); // NEED TO MOCK THIS EVENT LISTENER

        // Open Dialog box and ask user for a file. Only use .txt or .csv files
        fileReference.browse([textTypes]);       // NO NEED TO MOCK THIS
    }

The function under test takes the Event and works on the event.target

public function fileLoadCompleteHandler(event:Event):void
{
var currentFileReference:FileReference = FileReference(event.target);
}
}

As usual would appreciate your help on this.

Thanks
Des

Publish SWC

Compile and package a zip with source, SWC, ASDocs and publish to github downloads.

MockolateRule shortcuts signatures dont match package-level functions

Allow Partial Mock Objects

A Partial Mock Object should by default call the super method or property unless an Expectation has been defined.

Unexpected "ReferenceError: Variable <stubbed class> is not defined" with RemoteObject

I'm trying to mock a RemoteObject:

    service = strict(RemoteObject);
    stub(service).method("getOperation").args(anything()).returns(null);
    var x:* = service.getOperation("asdf");

But, on the last line (var x:* = service.getOperation(...)), I get this error:

        ... snip ...
        at tests.global.services::TestService/testRealCallWithError()[.../services/TestService.as:122]

    ReferenceError: Error \#1065: Variable RemoteObject4570E96E984C736EA25B72EBC1E9FFEF3CE48081 is not defined.

I am (I believe) correctly preparing RemoteObject (using prepare(RemoteObject) in conjunction with Async.proceedOnEvent).

Is this a known error? Is there anything I can do about it?

Thanks,
David

Strange error when creating strict mock

Just upgraded to 0.12.2. I'm getting an odd error on just a couple of our existing test cases. We're preparing the mocks for this particular strict the same way we are with others. Haven't been able to find anything that makes this case unique yet.

mock a static function

Drew

Is there a way to mock out a Singleton instance? I have the following pretty stock Flex URLParser and need to test the logic of parsing the URL.

public class MainPresenter
{
public var browserManager:IBrowserManager;

    public function setIntialView():void
    {
        browserManager = BrowserManager.getInstance();
        browserManager.init();
        var object:Object = URLUtil.stringToObject(browserManager.fragment,"&");

}

Problem I hit is at the "getInstance" line, a new browserManager is set and the mock I do is cleared. I do not know if it is possible to mock static classes, specifically the BrowserManager & URLUtil classes. If I can mock them, then I can control the result.

Thanks
Des

stubbing method still results in method superclass being called

Heres the contents of my test:

stub(loginDelegate).method("login").args( array("username", "password") );

mock(loginDelegate).method("login").args( array("username", "password") ).twice();

loginDelegate.login("username", "password");
loginCommand.execute("UserName", "PassWord");

verify(loginDelegate);

I have a breakpoint within the loginDelegate.login() method ad it fires twice in this case. After stubbing the method I'm expecting it to not fire at all.

Possible TypeError with FU4.1 & MockolateRunner

Check the constructor signatures with the MockolateRunner parent class, possible mismatch causing runtime errors when linking against the FU4.1 and Mockolate SWCs.

Improve missing Expectation Error message

should be similar to the failure messages for received(), eg:

Error: No Expectations defined for GeoModel(model).getCountryRegions([Country code="NN" name="Never Never Land"], [object Responder])

currently:

Error: No Expectation defined for Invocation:[FloxyInvocation invocationType=METHOD name="getCountryRegions" arguments=[[Country code="NN" name="Never Never Land"], [object Responder]]]

Document using Hamcrest matchers

Add a section to the stubbing and mocking page about using Hamcrest matchers and how they interact with the Invocation for matching the arguments.

Include examples of invocations that will and won't match.

mocking spark.components.Window

I my test i'm preparing mock of subclass of spark.components.Window, like this:

        [Before(async, timeout=6000, order=1)]
        public function prepareMockolates():void {
            // SplashWindow is mxml component based on spark.components.Window
            Async.proceedOnEvent(this, prepare(SplashWindow), Event.COMPLETE);
        }

        [Before(order=2)]
        public function setUp():void {
            ...
            view = nice( SplashWindow );
            ...
        }

After update to version 0.11.0 test failed with this error:

VerifyError: Error #1053: Illegal override of mx.core::UIComponent/http://www.adobe.com/2006/flex/mx/internal::$removeChild() in asmock.generated.SplashWindow10E410F4882BDD7AD3A3288A2E60E403F04302CC.

I'm using flex sdk 4.1 and flexunit 4.1. With mockolate v0.10.0 this error didn't show up.

Add constructor overrides for special cases like NetStream

Something like:

mocks.addConstructorOverrideFor(NetStream, function(netStreamClass:Class, constructorArgs:Array):NetStream {
    var netConnection:NetConnection = new NetConnection();
    netConnection.connect(null);
    return new netStreamClass(netConnection)
});

new Runner syntax

Drew

Thought I'd try this approach to log our conversations. I tried the new notation you presented around the runner, but I must be doing something wrong?

Original code that works

import mockolate.*;
import mockolate.ingredients.answers.*;
import mockolate.prepare;

public class LoginPresentorTests
{   
    // SUT
    private var loginPresentor:LoginPresentor;
    // Mock for the Model within LoginPresentor
    private var loginModelMock:LoginModel;

    [Before(order=1, async, timeout=5000)]
    public function prepareMockolates():void
    {
        Async.proceedOnEvent(this, prepare(LoginModel), Event.COMPLETE);
    }

    [Before(order=2)]
    public function runBeforeEveryTest():void
    {
        loginPresentor = new LoginPresentor();
        // Event within the test and not on the LoginPresentor
    }


    [Test(async)]
    public function testLogin():void
    {
        // Mock the dependent classes
        loginModelMock = strict(LoginModel);
        // Stub
        // No current behavior to mock

        // Assign the mock to the LoginPresentor
        loginPresentor.loginModel = loginModelMock;

        Assert.assertNotNull("LoginModel Mock available", loginModelMock);

}

New code that fails

import mockolate.runner.MockolateRunner; MockolateRunner;

import org.flexunit.async.Async;

For a generated proxy class allow multiple interfaces and a single superclass

issue with flash builder code coverage plugin?

I just started using mockolate yesterday, and I'm enjoying the experience ;)

I noticed something though. I had a test that was making a nice mockolate out of a spark.components.Form. I was testing a function that takes a Form parameter and dynamically adds some FormItem objects to it. The test worked fine (FlexUnit4.1), although was very slow. However, if I ran the test runner while connecting to the FB code coverage plugin, the tests hang and never finish.

I'll switch to using an interface or something, but wanted to mention it. I can provide more details if it isn't easily reproducible.

Thanks for the great product!

Can you please provide an example for capture?

I am looking for the Easymock style capture where I can get access to the param and do any inspections to it.
