控制器在未声明茉莉花测试 [英] Controller undeclared in Jasmine test

问题描述

我有以下code茉莉测试。 ProjectConfigurationCtrl是控制器我试图测试的名称。

I have a following code for Jasmine testing. ProjectConfigurationCtrl is the name of controller I am trying to test.

describe('Unit test: ProjectConfiguration controller', function() {
 var scope, routeParams, infraService, controllerToTest;

// some stuff declaration skipped...

beforeEach(inject(function($injector) { // get all dependences
    routeParams = $injector.get('$routeParams');
    infraService = $injector.get('InfraService');
    $rootScope = $injector.get('$rootScope');
    scope = $rootScope.$new();
    scope.projectData = fakedDto;
    var $controller = $injector.get('$controller');
    controllerToTest = function() {
        return $controller('ProjectConfigurationCtrl', { // 
            '$scope': scope
        });
    };

 }));

// ...

 it('saves new project successfully', function() {
    var controller = controllerToTest();
    // here, I try to call test function in and check results...
     scope.clickUpdate(fakedDto); // <-- controller defines this function in given scope, so I hope it runs like this in test.

 });
}); // describe block ends

这code错误结束（因果报应/茉莉输出）：

this code ends up in error (karma/jasmine output):

minErr/<@C:/src/ClientApp/client/bower_components/angular/angular.js:78
loadModules/<@C:/src/ClientApp/client/bower_components/angular/angular.js:3703

TypeError: controllerToTest is not a function in C:/src/ClientApp/tests/unit/controllers/projectconfigcontroller.test.js (line 85)
@C:/src/ClientApp/tests/unit/controllers/projectconfigcontroller.test.js:85

可能是什么原因？

what could be the reason?

推荐答案

c0bra，叶廖氏在这里都有很好的点。

c0bra and Ye Lio both have good points here.

c0bra是正确的，你有没有所谓的业力/茉莉辅助方法，模块，包括含有ProjectConfigurationCtrl模块。

c0bra is right in that you have not called the karma/jasmine helper method 'module' to include the module that contains 'ProjectConfigurationCtrl'.

您需要添加类似以下内容：

You need to add something like the following:

beforeEach( module( 'module.containing.ProjectConfigurationCtrl' ) );

如果你不这样做运行上面的脚本时，你会得到像下面这样的错误：

If you don't do this you will get an error like the following when running the script above:

错误：[NG：AREQ]参数'ProjectConfigurationCtrl不是一个函数，得到了不确定

Error: [ng:areq] Argument 'ProjectConfigurationCtrl' is not a function, got undefined

不过，您所看到的错误类型错误：controllerToTest不是一个函数表示，不知怎的，controllerToTest是越来越设置其他地方的东西，不是一个函数

However, the error you are seeing "TypeError: controllerToTest is not a function" indicated that somehow controllerToTest is getting set somewhere else to something that is not a function.

如果没有这解决您的问题，请发表您的测试一个新的，完整版瓦特/替代上述建议。

If none of this fixes your problem please post a new, complete version of your test w/ the above suggestions in place.
