How do I test Angular pipes?

To test Angular pipes, you can use Jasmine and TestBed. Would you like a code example?

Yes, please provide a code example.

Here's a simple test for a custom pipe:

import { TestBed } from '@angular/core/testing';
import { MyCustomPipe } from './my-custom.pipe';

describe('MyCustomPipe', () => {
  let pipe: MyCustomPipe;

  beforeEach(() => {
    TestBed.configureTestingModule({});
    pipe = new MyCustomPipe();
  });

  it('should transform input correctly', () => {
    expect(pipe.transform('input')).toBe('expectedOutput');
  });
});

What if my pipe has dependencies?

If your pipe has dependencies, you can provide them in the TestBed configuration. Would you like to see an example?
