angulardart_test 6.2.6

Testing utilities for AngularDart including TestBed, ComponentFixture, fake async zone, and component testing helpers.

AngularDart Test

Testing utilities and helpers for AngularDart components.

Part of the AngularDart ecosystem.

Features

• Component testing - Test AngularDart components in isolation
• NgTestBed - Create and manage component test fixtures
• Test fixtures - Interact with rendered components
• Zone stabilization - Wait for async operations to complete
• Change detection - Trigger and verify view updates

Installation

Add to your pubspec.yaml:

dev_dependencies:
  angulardart_test: ^5.0.0
  build_runner: ^2.4.0
  build_test: ^2.2.0
  build_web_compilers: ^4.0.0

Quick Start

import 'package:angulardart/angular.dart';
import 'package:angulardart_test/angulardart_test.dart';
import 'package:test/test.dart';

import 'my_component.dart';
import 'my_component.template.dart' as ng;

void main() {
  ng.initReflector();
  tearDown(disposeAnyRunningTest);

  test('should render greeting', () async {
    final testBed = NgTestBed<HelloComponent>();
    final fixture = await testBed.create();
    
    expect(fixture.text, contains('Hello'));
    
    await fixture.update((c) => c.name = 'World');
    expect(fixture.text, contains('Hello World'));
  });
}

Testing with NgTestBed

Create a test fixture

final testBed = NgTestBed<MyComponent>();
final fixture = await testBed.create();

Access component instance

final component = fixture.rootElement.componentInstance;

Update component state

await fixture.update((c) {
  c.name = 'New Value';
});

Query DOM elements

final element = fixture.rootElement.querySelector('.my-class');
expect(element.text, 'Expected text');

Trigger events

await fixture.update((c) {
  c.onButtonClick();
});

Testing with Dependencies

test('should work with services', () async {
  final testBed = NgTestBed<MyComponent>(
    beforeChangeDetection: (component) {
      component.service = MockService();
    },
  );
  
  final fixture = await testBed.create();
  expect(fixture.text, contains('Data from mock'));
});

Async Testing

AngularDart tests run in zones. Use tearDown to clean up:

import 'package:angulardart_test/angulardart_test.dart';

void main() {
  tearDown(disposeAnyRunningTest);
  
  test('async test', () async {
    final testBed = NgTestBed<MyComponent>();
    final fixture = await testBed.create();
    
    // Wait for async operations
    await fixture.update((c) {});
  });
}

Configuration

Add to your pubspec.yaml:

dev_dependencies:
  build_runner: ^2.4.0
  build_test: ^2.2.0
  build_web_compilers: ^4.0.0

Run tests:

dart run build_runner test -- -p chrome
