How do I test routing guards in Angular CLI?

To test routing guards in Angular CLI, you can use Jasmine and TestBed to create a testing module.

Can you provide a code example for testing a route guard?

Sure! Here's a simple example:

import { TestBed } from '@angular/core/testing';
import { RouterTestingModule } from '@angular/router/testing';
import { MyGuard } from './my-guard.service';

describe('MyGuard', () => {
  let guard: MyGuard;

  beforeEach(() => {
    TestBed.configureTestingModule({
      imports: [RouterTestingModule],
      providers: [MyGuard]
    });
    guard = TestBed.inject(MyGuard);
  });

  it('should be created', () => {
    expect(guard).toBeTruthy();
  });
});

What should I do if my guard fails the test?

If your guard fails the test, check the logic in your guard implementation and ensure that the conditions are correctly set up.

Are there any best practices for testing route guards?

Yes, some best practices include isolating tests, using spies for dependencies, and testing both allowed and denied routes.
