Unable to perform surveillance on the htpp.get method

Example snippet:

if (!this.scope.popupHtmlTemplate) {
    this.$http.get("widgets/pinpointcomponent/browseLibraries/resources/browseLibrariesDialogModal.html")
    .success((data: any) => {
        console.log("Processing success"+data)
        if (data) {
            this.generateBootBoxDialog(data);
            this.scope.popupHtmlTemplate = data;
        }
    });
} else {
    this.generateBootBoxDialog(this.scope.popopupHtmlTemplate)
}

Scenario:

it("test scenario expandLibrary 3", () => {
    spyOn(http, "get");
    controller.showBrowseLibrariesDialog();
     expect(http.get).toHaveBeenCalled();
});

Error message received:

TypeError: undefined is not a constructorevaluating 'spyOn(http, "get")) error.

Suggestions for creating a test case to resolve this issue.

Answer №1

Firstly, it seems like you're monitoring an unspecified http service rather than $http. For a more comprehensive approach, consider simulating those $http requests using $httpBackend from the ngMocks library.

AngularJS: API: $httpBackend

This method not only enables you to advise the test to anticipate an invocation of $http utilizing methods such as $httpBackend.expectGET();, but also allows you to mimic calls, trigger digests with $httpBackend.flush();, and simulate the response.
