Jasmine-测试一个具有Parameter函数的方法

Question

我试图测试一个以Object和Function为参数的方法，希望它是用它的Object和Function调用的，但即使我传递了一个函数，它也会返回一个错误。

Expected spy openContactEdit to have been called with [ Object({ ... }),
Function ] but actual calls were [ Object({ ... }), Function ].

我的代码是这样的：

联系编辑测试

class ModalControllerMock {
static create(page: any, data?: any) {
return new ModalMock;
}
}
class ModalServiceMock {
openContactEdit(contact: any, onDismiss: (data) => any): any {
let modal = ModalControllerMock.create('EditContactPage', {
contact: contact
})
modal.present();
let data: any;
onDismiss(data);
}
}
it('should open edit contact page', () => {
const contact = {
"username": "callain0",
"name": "Cordelia Allain"
}
spyOn(modalService, 'openContactEdit').and.callThrough();
comp.editContact(contact)
expect(modalService.openContactEdit).toHaveBeenCalledWith(contact, () => { });
});

模式服务.ts

openContactEdit(contact: any, onDismiss: (data) => any) {
let modal = this.modalCtrl.create('EditContactPage', {
contact: contact
})
modal.onDidDismiss(data => {
onDismiss(data);
})
modal.present();
}

将() => {}替换为jasmine.any(Function)，如果您不关心特定的函数，则会对您进行设置。请参见此处。
