### `.toHaveBeenCalled()`

Also under the alias: `.toBeCalled()`

Use `.toHaveBeenCalledWith` to ensure that a mock function was called with specific arguments. The arguments are checked with the same algorithm that `.toEqual` uses.

For example, let's say you have a `drinkAll(drink, flavour)` function that takes a `drink` function and applies it to all available beverages. You might want to check that `drink` gets called for `'lemon'`, but not for `'octopus'`, because `'octopus'` flavour is really weird and why would anything be octopus-flavoured?

Use `.toHaveBeenCalledTimes` to ensure that a mock function got called exact number of times.

For example, let's say you have a `drinkEach(drink, Array<flavor>)` function that takes a `drink` function and applies it to array of passed beverages. You might want to check that drink function was called exact number of times. You can do that with this test suite:

Also under the alias: `.lastCalledWith(arg1, arg2, ...)`

If you have a mock function, you can use `.toHaveBeenLastCalledWith` to test what arguments it was last called with. For example, let's say you have a `applyToAllFlavors(f)` function that applies `f` to a bunch of flavors, and you want to ensure that when you call it, the last flavor it operates on is `'mango'`.
