Create global spy/mock for jest

[cspritchard]

I want to create a global spy for console.log so that I do not see its output in my unit tests from services.

I have created a jest.setup.js file:

global.spyOnConsoleLog = () => {
  beforeAll(() => {
    jest.spyOn(console, 'info').mockImplementation(() => {});
    jest.spyOn(console, 'log').mockImplementation(() => {});
    jest.spyOn(console, 'error').mockImplementation(() => {})
  });

  afterAll(() => {
    jest.restoreAllMocks();
  });
}

global.spyOnConsoleLog();

And in my jest.config.ts i added:

import { getJestProjects } from '@nx/jest';

export default {
  projects: getJestProjects(),
  passWithNoTests: true,
  setupFilesAfterEnv: ['<rootDir>/jest.setup.js'],
};

However, when I run the unit tests for the project, the spy does not get used and console.log is called normally.

What am i missing in order to make global spy/mocks in jest that will be applied to all unit tests across my libs?
