Suggest using toBeCalledWith() or toHaveBeenCalledWith() (prefer-called-with)

The toBeCalled() matcher is used to assert that a mock function has been called one or more times, without checking the arguments passed. The assertion is stronger when arguments are also validated using the toBeCalledWith() matcher. When some arguments are difficult to check, using generic match like expect.anything() at least enforces number and position of arguments.

This rule warns if the form without argument checking is used, except for .not enforcing a function has never been called.
