Pattern: Use of restricted matcher

Issue: -

Description

Some Jest matchers may be restricted to enforce better testing practices or maintain consistency across test suites. Alternative matchers may be suggested based on project requirements.

Examples

Example of incorrect code:

expect(value).toBeFalsy();
await expect(promise).resolves.toBe(true);
expect(mock).not.toHaveBeenCalledWith("param");

Example of correct code:

expect(value).toBe(false);
await expect(promise).rejects.toThrow();
expect(mock).toHaveBeenCalledWith("expectedParam");
