I am seeking guidance on writing a proper unit test for a service using the jasmine framework and karma as the test runner.
Below is the implementation in example-service.js:
export default class ExampleService {
constructor($resource, $http, $urlMatcherFactory) {
'ngInject';
this.$resource = $resource;
this.$http = $http;
this.$urlMatcherFactory = $urlMatcherFactory;
}
exampleMethodOne() {
//some code lines
}
exampleMethodTwo() {
//some code lines
}
}
ExampleService.selector = 'myExampleService';
And here is what I have written in my test file example-service.test.js
let myExampleService, $httpBackend, $urlMatcherFactory;
beforeEach(() => {
angular
.module('exampleApp', ['ngResource'])
.service(ExampleService.selector, ExampleService);
angular.mock.module('exampleApp');
});
beforeEach(inject((_myExampleService_, _$httpBackend_,
_$urlMatcherFactory_) => {
myExampleService = _myExampleService_;
$httpBackend = _$httpBackend_;
$urlMatcherFactory = _$urlMatcherFactory_;
}));
I have included the imports for angular-mocks.js, angular-resource.js and example-service.js
However, when running this scenario, an
Error: [$injector:unpr] Unknown provider: $urlMatcherFactoryProvider <- $urlMatcherFactory <- myExampleServiceI would appreciate any assistance in resolving this issue. Thank you!
