[Unit Testing] Directive testing, isolated scope. 2

在测试文件中使用的scope是inject进去的，所以使用scope.clicked也可以找到原来directive定义的scope.

但是如果在driectvie中使用了isolated scope:

app.directive('testDir',function(){
    return{
        scope: {},
        link: linkFn
    }
    function linkFn(scope, element){
        element.addClass('panel');
        element.bind("click",function(){
            $scope.clicked = true;
        })
    }
})

 

我们再在测试文件中使用scope.clicked就会报错，这时候应该使用：

element.scope()

 

    describe("testDir", function() {
        it("should add a class of panel", function() {
            expect(element.hasClass("panel")).toBe(false);
        })

        it("should reponse click", function(){
            browserGTrigger(element, "click")
            expect(element.scope().clicked).toBe(true);
        })
    })

 

---------------------------------------------------

browserGTrigger 是在angular-scenario.js中定义的，
using the package https://npmjs.org/package/karma-ng-scenario fixed the problem for me. In short:
npm install karma-ng-scenario,
then add 'ng-scenario' to the 'frameworks' section in karma.conf.js.
