Example 2.js

describe("deletePost", () => {
    test("calls the REST API method to delete the post, but only if the user is logged in", () => {
        const mockUser = new User({ username: "bob" });

        mockUser.ajax = spy();

        mockUser.login();
        mockUser.deletePost();

        expect(mockUser.ajax).to.haveCallCount(1);

        mockUser.logout();
        mockUser.deletePost();

        expect(mockUser.ajax).to.haveCallCount(0);
    });
});
