单元测试 – 使用Mocha和Chai测试Angular

2023年4月1日 216次阅读

我想用Yeoman测试我的角度应用程序,它使用Mocha和Phantom和Chai进行断言.

但是,当我运行任何样本测试用例时,测试用例运行不正常,显示PhantomJs由于缺少Mocha run()调用而超时.非角度案例在测试用例中工作正常.

         /*   var deferred = $q.defer();
            var promise = deferred.promise;
            var resolvedValue;

            promise.then(function(value) { resolvedValue = value; });
            expect(resolvedValue).to.be.undefined;

            // Simulate resolving of promise
            deferred.resolve(123);
            // Note that the 'then' function does not get called synchronously.
            // This is because we want the promise API to always be async, whether or not
            // it got called synchronously or asynchronously.
            expect(resolvedValue).to.be.undefined

            // Propagate promise resolution to 'then' functions using $apply().
            $rootScope.$apply();
            expect(resolvedValue).to.equal(123);*/

最佳答案 你尝试过使用量角器吗？它专为测试端到端angularjs应用程序而开发(由angularjs团队提供).
https://github.com/angular/protractor

它有自己的跑步者,你可以安装：

npm install protractor -g

然后执行跑步者：

protractor /configfile.cfg

不需要HTML页面来运行测试.

配置文件非常简单(您可以在源代码中看到选项).

有了它,您将规范定义为：

// myTest.js
describe('angularjs homepage', function() {
    it('should greet the named user', function() {
        browser.get('http://www.angularjs.org');
        element(by.model('yourName')).sendKeys('Julie');

        var greeting = element(by.binding('yourName'));

        expect(greeting.getText()).toEqual('Hello Julie!');
      });
});
