ng-automocks

ng-automocks-jest is a Jest preset that simplifies Angular unit testing by automatically generating stubs for Angular entities when modules are mocked. It addresses common pain points like injection errors and boilerplate stub creation, allowing developers to focus on writing test assertions rather than setup code.

Key Features

• Automatic Mock Generation — Replaces Angular components, directives, pipes, modules, and services with safe stubs when using jest.mock(), eliminating manual stub creation.
• Injection Error Prevention — Fixes Jest's default auto-mocks that break Angular dependency injection by providing stub factories that return valid instances.
• External Dependency Isolation — Enables mocking entire Angular libraries with a single jest.mock() call, stubbing all their components, directives, and pipes.
• Seamless Integration — Stubbed entities preserve public APIs like selectors and input properties, allowing templates to render without errors while original logic is bypassed.
• Customizable Behavior — Generated stubs are Jest mocks under the hood, allowing method behavior to be overridden with .mockReturnValue() or .mockImplementation() as needed.

Philosophy

The project believes Angular testing should be straightforward and boilerplate-free, leveraging Jest's mocking capabilities to automatically handle Angular-specific complexities, so developers can write focused unit tests efficiently.
