'Is there any way to mock API responses using snapshots?
I'm currently trying to find a good way to mock API responses for a subset of end-to-end tests, and was thinking it would be swell if there was a way to take snapshots when the backend services are healthy, and then use those snap-shotted responses in place of making actual HTTP requests when the tests are being run. Does anyone know if a library exists for this sort of thing?
Basically, I'd like to do something like the following:
it('does something', () => {
const data = process.env.UPDATE_SNAPSHOTS ? getDataFromServer() : getDataFromSnapshot();
saveSnapshot(data); // Saves snapshot data to file system like jest
// Test things using "data"
});
It would be great if I could just use jest for this, since I'm using jest anyway. But as far as I can tell, jest doesn't have any file-based snapshot methods besides toMatchSnapshot() and I really need to be able to saveSnapshot() and readSnapshot() arbitrarily.
