大佬教程收集整理的这篇文章主要介绍了angularjs – 创建和创建pyobj之间有什么区别?,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
return $provide.decorator('aservice',function($delegatE) { $delegate.addFn = jasmine.createSpy().andReturn(true); return $delegate; });@H_450_3@那么createSpy在做什么呢?我可以将createSpy@L_874_2@更改为createdpyobj@L_874_2@。 @H_450_3@通过使用createSpy,我们可以创建一个函数/方法mocks。 Createspyobj可以做多个功能模拟。我对吗? @H_450_3@会有什么区别?
describe("A spy,when created manually",function() { var whatAmI; beforeEach(function() { whatAmI = jasmine.createSpy('whatAmI'); whatAmI("I","am","a","spy"); }); it("is named,which Helps in error reporTing",function() { expect(whatAmI.and.identity()).toEqual('whatAmI'); }); it("tracks that the spy was called",function() { expect(whatAmI).toHaveBeenCalled(); }); it("tracks its number of calls",function() { expect(whatAmI.calls.count()).toEqual(1); }); it("tracks all the arguments of its calls",function() { expect(whatAmI).toHaveBeenCalledWith("I","spy"); }); it("allows access to the most recent call",function() { expect(whatAmI.calls.mostRecent().args[0]).toEqual("I"); }); });@H_450_3@createSpyObj:
describe("Multiple spies,function() { var tape; beforeEach(function() { tape = jasmine.createSpyObj('tape',['play','pause','stop','rewind']); tape.play(); tape.pause(); tape.rewind(0); }); it("creates spies for each requested function",function() { expect(tape.play).toBeDefined(); expect(tape.pausE).toBeDefined(); expect(tape.stop).toBeDefined(); expect(tape.rewind).toBeDefined(); }); it("tracks that the spies were called",function() { expect(tape.play).toHaveBeenCalled(); expect(tape.pausE).toHaveBeenCalled(); expect(tape.rewind).toHaveBeenCalled(); expect(tape.stop).not.toHaveBeenCalled(); }); it("tracks all the arguments of its calls",function() { expect(tape.rewind).toHaveBeenCalledWith(0); }); });
