Before, all test framework wrappers (internal for dart and js/ts, angular2_test for dart and testing for js/ts) had similar logic to keep track of current global test injector and test provider list. This change wraps that logic into one class managed by the test injector. Closes #5819
Contains helpers to run unit tests for angular2 components and injectables,
backed by the package:test library.
Usage
Update the dev dependencies in your pubspec.yaml to include the angular testing
and test packages:
dev_dependencies:
test: '^0.12.6'
angular2_testing: any
Then in your test files, use angular2_testing helpers in place of setUp and test:
import 'package:test/test.dart';
import 'package:angular2_testing/angular2_testing.dart';
void main() {
// This must be called at the beginning of your tests.
initAngularTests();
// Initialize the injection tokens you will use in your tests.
setUpProviders(() => [provide(MyToken, useValue: 'my string'), TestService]);
// You can then get tokens from the injector via ngSetUp and ngTest.
ngSetUp((TestService testService) {
testService.initialize();
});
ngTest('can grab injected values', (@Inject(MyToken) token, TestService testService) {
expect(token, equals('my string'));
expect(testService.status, equals('ready'));
});
}
Examples
A sample test is available in test/angular2_testing_test.dart.
