问题 Before marking this as a duplicate of this question please note that I'm asking specifically about Angular 10+, because the answers to that question no longer work as of Angular 10. Background I've created a simple example app that helps illustrates my question. The idea with this app is that several "people" will say "hello", and you can respond to any or all of them by typing their name. It looks like this: (Note that the 'hello' from Sue has been greyed out because I responded by typing

问题 I have a function which I want to unit-test and into it I am comparing global objects window & parent as const isEqual = (window === parent) ; Which is the best way how to mock those objects in Angular/TypeScript? One more idea is to get those objects through function parameters, but anyway it's not solving this problem because I need to mock global window object too if I am using getSomeData(win: Window, parent: Window) { // ... } 回答1: I went with this solution: Create service which will

问题 I am trying to test a function that unsubscribes from all subscriptions: ngOnDestroy() { this.tryUnsubscribe(this.carsSubscription); this.tryUnsubscribe(this.partsSubscription); this.tryUnsubscribe(this.shopsSubscription); } This is the test I wrote for the function: it('should unsubscribe from subscriptions ', () => { spyOn(component, "tryUnsubscribe"); component.ngOnDestroy(); expect(component.tryUnsubscribe).toHaveBeenCalledWith(component['carsSubscription']); expect(component

问题 When I unit test my getters are setters for Typescript, I cannot find a way to spy on those getters and setters. Instead, the object immediately gets evaluated. I am using Jasmine to unit test. 回答1: It is not supported yet, but there is a Jasmine issue for supporting getters. If you really need the support now, you can extend SpyRegistry.js file and add the code that apsillers proposed: this.spyOnProperty = function(obj, methodName, accessType) { ... var desc = Object.getPropertyDescriptor

问题 I'm currently investigating Google Cloud Functions and have some basic test functions written in typescript. The functions work as expected and I am now attempting to create unit tests using Jasmine. (I'm not using Chai/sinon as per the docs as the rest of my project uses jasmine). I have two issues 1) the test does not run due to this error throw new Error('Firebase config variables are not available. ' + ^ Error: Firebase config variables are not available.
