An example of an AI chatbot conversation about testing async code in Vue.js with Jest.
How do I test asynchronous code in Vue.js using Jest?
To test asynchronous code in Vue.js with Jest, you can use the async and await keywords along with Jest's built-in functions.
Can you give me an example of testing a Vue component that fetches data?
Sure! You can mock the API call and use wrapper.vm.$nextTick() to wait for the component to update after the data is fetched.
What if I want to test a promise that resolves after a delay?
You can use Jest's jest.advanceTimersByTime() to simulate the passage of time and resolve the promise.
Are there any specific Jest matchers I should use for async tests?
Yes, you can use matchers like toBeTruthy(), toEqual(), or toHaveBeenCalled() to assert the expected outcomes in your async tests.
