jasmine

I'm testing a function that takes a date as an optional argument. I want to assert that a new Date object is created if the function is called without the argument. var foo = function (date) { var d = date || new Date(); return d.toISOString(); } How do I assert that new Date is called? So far, I've got something like this: it('formats today like ISO-8601', function () { spyOn(Date, 'prototype'); expect().toHaveBeenCalled(); }); See: https://github.com/pivotal/jasmine/wiki/Spies Credit to @HMR. Test I wrote to verify: it('Should spy on Date', function() { var oldDate = Date; spyOn(window,

I'm creating a unit test for my Navbar Component and I'm getting an error: Can't bind to 'routerLink' since it isn't a known property of 'a' Navbar Component TS import { Component } from '@angular/core'; import { Router } from '@angular/router'; import { NavActiveService } from '../../../services/navactive.service'; import { GlobalEventsManager } from '../../../services/GlobalEventsManager'; @Component({ moduleId: module.id, selector: 'my-navbar', templateUrl: 'navbar.component.html', styleUrls:['navbar.component.css'], providers: [NavActiveService] }) export class NavComponent { showNavBar:

Jasmine是一个很好的单元测试框架，它有漂亮简单的API describe('you can group test cases in "describe" blocks...', function() { 　　　　describe('...which can also be nested', function() { 　　　　　　　　it('test cases are in "it" blocks', function() { 　　　　　　　　var string = 'where we can run arbitrary JavaScript code...'; // ...and make assertions about results using "expect": 　　　　　　　　expect(string).toEqual('expected string'); 　　　　　　}); 　　　　}); }); 　　 Karma 是一个集成了像 Jasmine（基于 BDD 的测试框架），PhantomJS（无界面的浏览器）等的测试工具。 npm安装好后，就要写karma的配置文件 //karma.conf.js module.exports = function(config) { config.set({ frameworks: ['jasmine'], files

I am new to Angular 2 testing. I am trying to figure out what is the difference in using testsbed.get() and just using inject at the test level. eg: beforeEach(() => { TestBed.configureTestingModule({ providers: [SomeService] }); const testbed = getTestBed(); someService= testbed.get(SomeService); }); }); vs it('test service', inject([SomeService], (someService: SomeService) => { inject helper function was historically used since AngularJS as an alternative to direct injector calls. In Angular 1, it was necessary to bootstrap a test with ngMock . It is entirely optional in Angular 2 and higher

I am using folloing jasmine test case 'use strict'; describe('companyService', function() { var $httpBackend, companyService; beforeEach(angular.mock.module('myApp')); beforeEach(angular.mock.inject(function(_$httpBackend_ , _companyService_) { $httpBackend = _$httpBackend_; companyService = _companyService_; })); it('should return a promise for getCompany function', function() { // expect(typeof companyService.getCompany('foobar').then).toBe('function'); }); }); i am getting the following error . as you can see above . i am not doing anything inside it block . minErr/<@C:/Users/userone

例：写一个函数，接受一个整数，输出这个整数是几位数？ 注： / 是取整； %是取余； n%10是求得一个整数的最后一位数； import java.util.*; public class TestWeiShu{ public static void main(String[] args){ System.out.println("请输入一个整数:"); Scanner sc= new Scanner(System.in); int n=sc.nextInt(); int count=0; while(n!=0){ n=n/10; count++; } System.out.println("这个整数共有:"+count+"位"); } } 来源： CSDN 作者： tea_jasmine 链接： https://blog.csdn.net/tea_jasmine/article/details/83901080

I try to use wait() method instead sleep(), but it isn't working. I had code: browser.actions().click(filter_field).perform(); browser.sleep(3000); if (baloon_info.isPresent()) { //some expections } else { expect(true).toBe(false); } Now I want to do something like: var present_pri = browser.wait(function () { return balloon_info.isPresent(); }, 3000); if (present_pri) { //some expections } else { expect(true).toBe(false); } But if balloon isn't present I have the error message: Wait timed out after 3117ms instead expected true to be false (present_pri == false) I tryed to write: var EC =
