"Troubleshooting HTTP requests in Angular: Dealing with

I encountered an issue while attempting to test an http request with a dynamic URL.

Within my service file, I have the following snippet:

Snippet from My Service File:

//other service codes..
//other service codes..
var id = $cookies.id;
return $http.get('/api/product/' + id + '/description')
//id is dynamic 

Test File:

describe('test', function () {
    beforeEach(module('myApp'));

    var $httpBackend, testCtrl, scope;

    beforeEach(inject(function (_$controller_, _$httpBackend_, _$rootScope_) {
        scope = _$rootScope_.$new();
        $httpBackend = _$httpBackend_;
        testCtrl = _$controller_('testCtrl', {
            $scope: scope
        });
    }));

    it('should check the request', function() {
        $httpBackend.expectGET('/api/product/12345/description').respond({name:'test'});
        $httpBackend.flush();
        expect(scope.product).toBeDefined();
    })
});

Issue Description:

Error: Unexpected request: GET /api/product/description

I am unsure how to resolve this error related to testing the dynamic URL. Any assistance would be greatly appreciated. Thank you!

Answer №1

Your code is missing the id parameter, causing the URL to be incorrect:

/api/product//description

This results in an unexpected request due to the extra slashes (// -> /).

Make sure to define the id in your code. Check where you are setting it.

When testing dynamic URLs, ensure that you set up your tests to know and expect the value of id. You cannot rely on patterns in URLs.

To change the cookie value, adjust the first line in your describe block like this:

beforeEach(module('myApp', function($provide) {
  $provide.value('$cookies', {
    id: 3
  });
}));

Now, when making the URL call, you can expect the id to be three.

This method may seem basic. Alternatively, you can inject $cookies in the second beforeEach block and set it like so:

beforeEach(inject(function($cookies) {
    $cookies.put('id', 3);
}))
