angular的核心思想包含代码的可测试性,但同时也要求我们去做正确的事情。angular致力于简化做正确事情的方法,但angular不是魔法,这意味着我们如果不遵循以下的几点,我们最终可能会得出一个不可测试的应用。 1.Dependency Inject 有许多办法可以获得依赖的资源:1)我们可以使用new操作符;2)我们使用一个众所周知的方式,被称为”
if it is: * new-ed up, the the test has no chance to reset the services for testing * global look-up, then the service returned is global as well (but resetting is easier, since there is only one global variable to be reset)(这里后面的文字跟乱码一样……没看懂) 根据这个方法,将上面...
That code may be left in, however, allowing the service to be built manually or injected as such:import { TestBed, inject } from '@angular/core/testing';import { PayrollService } from './payroll.service';import { TaxService } from './tax.service';describe('PayrolService', () => { ...
In this chapter, I describe the tools that Angular provides for unit testing components and directives. Some Angular building blocks, such as pipes and services, can be readily tested in isolation using the basic testing tools that I set up at the start of the chapter. Components (and, to ...
It supports testing applications developed using AngularJS. Eliminates the need for many complex commands in traditional Selenium tools, making your test automation workflow more efficient. Gauge The creators of Selenium, Thoughtworks, have introduced a new Java testing framework called Gauge. It’s des...

[Unit Testing Angular] fakeAsync lua In this post, we are going to see how to use 'fakeAsync' to test async code in Angular Context. fakeAsync using Zoom.js underhook, it detects all the async operations. You can use the utilities function such as...
To fully unit test theActuateLights(bool motionDetected)method, we should perform interaction-based testing in addition to the state-based testing; that is, we should ensure that methods for turning the light on or off are called if, and only if, appropriate conditions are met. Unfortunately,...
