Objectives

• Test the API

Steps

Test the API

1. Create the file src\projects\__tests__\projectAPI-test.js.

2. Add the following code to test the updating of a project.

   src\projects\__tests__\projectAPI-test.js

   import { MOCK_PROJECTS } from '../MockProjects';
   import { projectAPI } from '../projectAPI';
   
   describe('projectAPI', () => {
     test('should return records', () => {
       const response = new Response(undefined, {
         status: 200,
         statusText: 'OK',
       });
       response.json = () => Promise.resolve(MOCK_PROJECTS);
       jest
         .spyOn(window, 'fetch')
         .mockImplementation(() => Promise.resolve(response));
   
       return projectAPI
         .get()
         .then((data) => expect(data).toEqual(MOCK_PROJECTS));
     });
   });

3. Verify the test passes.

    PASS  src/projects/__tests__/projectAPI-test.js
