# 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.
## Rule details
The following patterns are warnings:
```js expect(someFunction).toBeCalled();
expect(someFunction).toHaveBeenCalled(); ```
The following patterns are not warnings:
```js expect(noArgsFunction).toBeCalledWith();
expect(roughArgsFunction).toBeCalledWith(expect.anything(), expect.any(Date));
expect(anyArgsFunction).toBeCalledTimes(1);
expect(uncalledFunction).not.toBeCalled(); ```
