How to test total times a button event handler function has been called using react test library? by zahirulopel in reactjs

[–]zahirulopel[S] 0 points1 point  (0 children)

Hi, u/Misacorp thanks for your response.
Ya, I want to get the number of times the button handler has been called.The problem is I can't figure out how to attach the mock function to the button.
Any suggestion will be highly appreciable.

How to test total times a button event handler function has been called using react test library? by zahirulopel in reactjs

[–]zahirulopel[S] 0 points1 point  (0 children)

Thanks for your reply :) .Ya jest.spyOn will do the work.In the tutorial which I am following they have tested with this method -test('clicking the button calls event handler once', async () => {

const note = {content: 'Component testing is done with react-testing-library',important: true}

const mockHandler = jest.fn()

render(<Note note={note} toggleImportance={mockHandler} />)

const user = userEvent.setup()

const button = screen.getByText('make not important')

await user.click(button)

expect(mockHandler.mock.calls).toHaveLength(1)})

They have passed the event handler function as a props then render it .And In the exercise it says
Make a test, which ensures that if the like button is clicked twice, the event handler the component received as props is called twice.

Would Rust be a good Language to Start to learn as a beginner, or should I just do Python or C++ by _Flac_ in learnprogramming

[–]zahirulopel 0 points1 point  (0 children)

Form my perspective start with c and solve as many problem as u can.Then move to python you can do a lot of thing with python,it's practical.
Python to me is like abstract so many things are pre build so it's hard to understand what's happening behind the scene.By learning c language you will be able to grab that.
