最近我开始使用 karma-jasmine 对我的 typescript 代码进行单元测试。在为服务和简单指令创建并运行测试用例后,我为自定义指令创建了一个测试用例,它有一个 Controller (注入(inject)一项服务)并使用 4 个范围变量与外界通信。
这是一个简单的单元测试用例,用于检查指令是否呈现其模板。
在运行这个单元测试用例时,karma 抛出一些错误

在调试它时,我了解到它正在将“normal-directive”视为普通文本而不是 html 标签。
normal-directive.spec.ts
import {appName} from '../../../../main';
import NormalController from '../../../../components/normalManager/normalList/NormalController';
describe('normalManager.normalList', () => {
let $compile:angular.ICompileService,
$rootScope:any,
template:angular.IAugmentedJQuery,
element:angular.IAugmentedJQuery,
controller:NormalController,
controllerSpy:jasmine.Spy;
beforeEach(() => {
angular.mock.module(appName);
inject((_$compile_:ng.ICompileService, _$rootScope_:ng.IRootScopeService) => {
$compile = _$compile_;
$rootScope = _$rootScope_;
});
template = angular.element('<div normal-directive></div>');
element = $compile(template)($rootScope);//getting error on this line.
controller = element.controller('normalList');
$rootScope.$digest();
});
it('should render the component', () => {
expect(element.html()).toContain('<!-- normalManager.normalList -->');
});
});
normal-directive.ts
import * as angular from 'angular';
import {normalController} from './normalController';
import {html} from './normal.html'
module normal {
"use strict";
export class normal {
public link: (scope: ng.IScope, element: ng.IAugmentedJQuery, attrs: ng.IAttributes) => void;
public template = html;
public scope = {
ngNormalVariables: '=',
ngNormalData: '=',
ngDifferentType: '=',
ngType: '='
};
public restrict: string = 'EA';
public controller = normalController;
public controllerAs: string = 'vm';
public bindToController:boolean = true;
constructor() {
normal.prototype.link = (scope: ng.IScope, element: ng.IAugmentedJQuery, attrs: ng.IAttributes) => {
};
}
public static Factory() {
var directive = () => {
return new normal();
};
directive['$inject'] = [];
return directive;
}
}
}
export default normal;
normalController.ts
import {IfcNormalFacadeService} from '../../../normal_core/services/NormalFacadeService/IfcNormalFacadeService'
export class normalController {
//Variable injection
private normalFacadeService: IfcNormalFacadeService;
public xVariableVal = null;
public yVariableVal = null;
//Scope variables
private ngNormalData = {x:null, y:null, t:null, z:null};
private ngNormalVariables = {x: [], y:[], t:[], z:[]};
private ngType = null;
private ngDifferentType = null;
constructor(normalFacadeService: IfcNormalFacadeService) {
console.log("Inside Normal controller");
this.normalFacadeService = normalFacadeService;
}
....//Remaining code
}
我指的是 this repo 编写测试用例和 typescript 自定义指令代码。
如果您需要更多信息,请告诉我。如果你知道任何具体的博客/网站来了解更多关于 typescript 的 karma-jasmine 单元测试,请告诉我。
感谢您抽出宝贵时间阅读。

最佳答案
我需要为 facadeService 做一个模拟。
演示 mocks.ts
import {IfcFacadeService} from 'filePath'
export const facadeServiceMock: IfcFacadeService {
methodName: (): any => {};
}
要使用这个模拟,导入它
演示 .html.spec.ts
import {facadeServiceMock} from 'mockPathName'
beforeEach(()=>{
angular.mock.module(appName), {FacadeService: facadeServiceMock});
})
