What is the difference between ".toBeCalled" and ".toHaveBeenCalled"?

Question

When should each of these methods be called, and why?

const spyStart = spyOn(el, 'func1');
expect(spyStart).toHaveBeenCalled();


const spyStart = spyOn(el, 'func1');
expect(spyStart).toBeCalled();

Answer 1

Actually .toBeCalled is an alias to .toHaveBeenCalled, so they do the same thing.

From the docs:

.toHaveBeenCalled() Also under the alias: .toBeCalled()
