Testing Lab 9: API Tests

Objectives

• Test the API

Steps

Test the API

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

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

   src\projects\__tests__\projectAPI-test.ts

   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.ts
