How To Test Done Part Of Ajax In Jasmine
I really like this resource for AJAX in general and it works in terms of testing a success or error function that's within the AJAX parameters. However, when I instead choose to no
Solution 1:
Well, probably the example in the question is not the same you are running local, but it should fail in the line spyOn($, "ajax").and.callFake(deferred)
because callFake
expect a function and deferred
is not. Instead, deferred
should be a resolved Promise and use .and.returnValue
instead of .and.callFake
.
Here is a working example:
functionitWorked() {
console.log("It worked!!");
}
functionsendRequest(callbacks, configuration) {
$.ajax({}).done(function(response) {
itWorked();
});
}
describe("Ajax Tests", () => {
beforeEach(function() {
spyOn(window, "itWorked").and.callThrough();
deferred = $.Deferred().resolve(); // Call resolvespyOn($, "ajax").and.returnValue(deferred); // Use return valuesendRequest();
});
it("should work", function() {
expect($.ajax).toHaveBeenCalled(); // passexpect(window.itWorked).toHaveBeenCalled(); // pass
});
});
Note that I've added console.log("It worked!!");
and use .and.callThrough();
just to double check in the console that "It worked!!" was logged.
When calling $.Deferred().resolve() you can pass a mocked response to deal with in your .done
or .then
callback. Something like .resolve({ success: true })
. Check an example here
Hope it helps
