Pattern: Use of deprecated Jest function

Issue: -

Description

Some Jest functions have been renamed or replaced with more powerful APIs. Using deprecated functions makes code harder to maintain and may break in future Jest versions.

Examples

Example of incorrect code:

jest.resetModuleRegistry();
jest.addMatchers();
jest.runTimersToTime(1000);
jest.genMockFromModule("./module");

Example of correct code:

jest.resetModules();
expect.extend();
jest.advanceTimersByTime(1000);
jest.createMockFromModule("./module");
