createAngularJSTestingModule
stringA helper function to use when unit testing AngularJS services that depend upon downgraded Angular services.
This function returns an AngularJS module that is configured to wire up the AngularJS and Angular injectors without the need to actually bootstrap a hybrid application. This makes it simpler and faster to unit test services.
Use the returned AngularJS module in a call to
angular.mocks.module to
include this module in the unit test injector.
In the following code snippet, we are configuring the $injector with two modules:
The AngularJS ng1AppModule, which is the AngularJS part of our hybrid application and the
Ng2AppModule, which is the Angular part.
{@example upgrade/static/ts/full/module.spec.ts region='angularjs-setup'}
Once this is done we can get hold of services via the AngularJS $injector as normal.
Services that are (or have dependencies on) a downgraded Angular service, will be instantiated as
needed by the Angular root Injector.
In the following code snippet, heroesService is a downgraded Angular service that we are
accessing from AngularJS.
{@example upgrade/static/ts/full/module.spec.ts region='angularjs-spec'}
This helper is for testing services not components.
For Component testing you must still bootstrap a hybrid app. See UpgradeModule or
downgradeModule for more information.
The resulting configuration does not wire up AngularJS digests to Zone hooks. It is the
responsibility of the test writer to call $rootScope.$apply, as necessary, to trigger
AngularJS handlers of async events from Angular.
The helper sets up global variables to hold the shared Angular and AngularJS injectors.
- Only call this helper once per spec.
- Do not use
createAngularJSTestingModulein the same spec ascreateAngularTestingModule.
Here is the example application and its unit tests that use createAngularTestingModule
and createAngularJSTestingModule.
