我的组件具有以下功能:
updateTransactions() {
let notes = this.createNotes()
let delTransactions = this.createDelTransactions()
this.noteService.createNote(notes[0])
this.noteService.getNoteCreated().subscribe((res) => {
notes.shift();
if(res && notes.length > 0) {
this.noteService.createNote(notes[0])
} else {
this.deliverableTransactionService.updateDeliverableTransaction(delTransactions[0].id, delTransactions[0])
}
})
this.deliverableTransactionService.getUpdateDeliverableTransactionStatus().subscribe((res) => {
delTransactions.shift();
if(res && delTransactions.length > 0) {
this.deliverableTransactionService.updateDeliverableTransaction(delTransactions[0].id, delTransactions[0])
} else {
this.closeModal();
}
})
console.log('current note', this.note)
}
我的测试如下:
it('should initialize properly when updating', () => {
let testTransactions = [{id: 1}]
let dueDate = '1/2/3'
let testNote = 'Test'
component.deliverableTransactions = testTransactions
component.dueDate = dueDate
component.note = testNote
spyOn(component, 'createNotes').and.callThrough();
spyOn(component, 'createDelTransactions').and.callThrough();
spyOn(noteService, 'createNote').and.returnValue(true);
spyOn(noteService, 'getNoteCreated').and.returnValue({subscribe: () => true});
spyOn(deliverableTransactionService, 'getUpdateDeliverableTransactionStatus').and.returnValue({subscribe: () => true});
component.updateTransactions();
expect(component.createNotes).toHaveBeenCalled();
expect(component.createDelTransactions).toHaveBeenCalled();
expect(noteService.createNote).toHaveBeenCalled();
expect(noteService.getNoteCreated).toHaveBeenCalled();
expect(deliverableTransactionService.getUpdateDeliverableTransactionStatus).toHaveBeenCalled();
})
我已经定义了各种服务:
beforeEach(async(() => {
fixture = TestBed.createComponent(ChangeDueDateComponent);
component = fixture.componentInstance;
fixture.detectChanges();
deliverableTransactionService = TestBed.get(DeliverableTransactionService);
noteService = TestBed.get(NoteService);
activeModal = TestBed.get(NgbActiveModal);
}));
然而,当我运行测试时,我收到一个错误:
PhantomJS 2.1.1 (Windows 7 0.0.0) ChangeDueDateComponent should initialize properly when updating FAILED
Error: <spyOn> : getNoteCreated() method does not exist
我做错了什么?
我不知道为什么在getNoteCreated
上找不到noteService
。它应该在那里吗?
无论如何,您可以通过以这种方式创建间谍来避免错误:
noteService.getNoteCreated = jasmine.createSpy().and
.returnValue({subscribe: () => true});
您正在尝试从getNoteValue
而不是Observable
返回订阅。
以这种方式改变你的间谍:
spyOn(noteService, 'getNoteCreated').and.returnValue(Observable.of(true));
