    Rule Details

    This rule triggers a warning if the alias name, rather than the canonical name, of a method is used.

    The rule checks matchers written with dot access or a static bracket key such as expect(a)['toBeCalled'](). A matcher named by a variable, such as expect(a)[matcherName](), is ignored because its name is only known at runtime.

    Examples of incorrect code for this rule:

    expect(a).toBeCalled();
expect(a).toBeCalledTimes();
expect(a).toBeCalledWith();
expect(a).lastCalledWith();
expect(a).nthCalledWith();
expect(a).toReturn();
expect(a).toReturnTimes();
expect(a).toReturnWith();
expect(a).lastReturnedWith();
expect(a).nthReturnedWith();
expect(a).toThrowError();

    Examples of correct code for this rule:

    expect(a).toHaveBeenCalled();
expect(a).toHaveBeenCalledTimes();
expect(a).toHaveBeenCalledWith();
expect(a).toHaveBeenLastCalledWith();
expect(a).toHaveBeenNthCalledWith();
expect(a).toHaveReturned();
expect(a).toHaveReturnedTimes();
expect(a).toHaveReturnedWith();
expect(a).toHaveLastReturnedWith();
expect(a).toHaveNthReturnedWith();
expect(a).toThrow();
