How to mock environment files import in unit tests

Question

In our angular app, we use environment files to load some config.

environment.ts

export const environment = {
  production: false,
  defaultLocale: \'en         


        

Answer 1

Something like this worked for me:

it('should test', () => {
  environment.defaultLocale = ;

  const result = service.method();

  expect(result).toEqual();
});
