ng-mocks

What is ng-mocks?

ng-mocks is a powerful library for Angular that simplifies the process of creating mock components, directives, pipes, and services for unit testing. It helps developers to isolate the unit of work and test it without dependencies on other parts of the application.

What are ng-mocks's main functionalities?

Mock Components

This feature allows you to create mock versions of Angular components. This is useful for isolating the component under test from its child components.

import { MockComponent } from 'ng-mocks';
import { MyComponent } from './my-component';

TestBed.configureTestingModule({
  declarations: [MockComponent(MyComponent)]
});

Mock Directives

This feature allows you to create mock versions of Angular directives. This is useful for isolating the component under test from its directives.

import { MockDirective } from 'ng-mocks';
import { MyDirective } from './my-directive';

TestBed.configureTestingModule({
  declarations: [MockDirective(MyDirective)]
});

Mock Pipes

This feature allows you to create mock versions of Angular pipes. This is useful for isolating the component under test from its pipes.

import { MockPipe } from 'ng-mocks';
import { MyPipe } from './my-pipe';

TestBed.configureTestingModule({
  declarations: [MockPipe(MyPipe)]
});

Mock Services

This feature allows you to create mock versions of Angular services. This is useful for isolating the component under test from its services.

import { MockProvider } from 'ng-mocks';
import { MyService } from './my-service';

TestBed.configureTestingModule({
  providers: [MockProvider(MyService)]
});

Other packages similar to ng-mocks

jest

Jest is a delightful JavaScript testing framework with a focus on simplicity. It provides a powerful mocking library that can be used to mock functions, modules, and timers. While Jest is not specific to Angular, it can be used in conjunction with Angular to achieve similar mocking capabilities.

sinon

Sinon is a standalone test spies, stubs, and mocks library for JavaScript. It works with any unit testing framework and provides powerful mocking capabilities. Like Jest, Sinon is not specific to Angular but can be used to mock dependencies in Angular applications.

ts-mockito

ts-mockito is a mocking library for TypeScript inspired by the Java library Mockito. It provides a simple API for creating mock objects and verifying interactions. ts-mockito is not specific to Angular but can be used to mock dependencies in Angular applications.

The plan is to merge these mock libraries into one but for now is an export of the 3 packages:
