Jest test for console.warn & console.error
// In case you are tired of seeing warning and error messages in your tests add these
// few lines of code to your setupTests.js file.

// Any test that outputs console.error or console.warn will fail allowing you to easily
// identify where the log came from so you can address it accordingly
const spyError = jest.spyOn(global.console, 'error');
