How to mock different APIs in a test file?

[ritvik130]

I am converting got to undici I have numerous APIs in a single file that I want to mock, and using setGlobalDispatcher works for only one URL in a file.

I have written the following test to convert got to undici but I do have a lot more tests that use different URLs

const agent = new MockAgent();

agent.disableNetConnect();

const mockAgent = agent.get('https://test.ca');

setGlobalDispatcher(mockAgent);



describe('REST', () => {

  beforeEach(async () => {

    await rest.initialize();

    nock.cleanAll();

    clearTokens();

  });

  afterEach(async () => {

    await agent.close();

    await rest.shutdown();

  }); 
  describe('REST pass', () => {

    it('200', async () => {

      nock('https://test.ca')

        .get('/test')

        .reply(200, {

          data: 'test',

        });

      const result = await rest.get('test', 'test');

      assert.equal(result.statusCode, 200);

      assert.deepEqual(result.body, { data: 'test' });

      assert.isTrue(nock.isDone());

    });

    it('200 - undici', async () => {

      mockAgent

        .intercept({

          path: '/test',

          method: 'GET',

        })

        .reply(200, {

          data: 'test',

        });

      const result = await rest.get('test', 'test');

      assert.equal(result.statusCode, 200);

      assert.deepEqual(result.body, { data: 'test' });

      agent.assertNoPendingInterceptors();

    });

For example, I would also like to include the following test:

   it('200 post - undici', async () => {

      const mockAgent = agent.get('https://testing.ca');

      mockAgent

        .intercept({

          path: '/test',

          method: 'POST',

        })

        .reply(200, {

          data: 'test',

        });

      const result = await rest.post('test', 'test', '{"data":"testBody"}');

      assert.equal(result.statusCode, 200);

      assert.deepEqual(result.body, { data: 'test' });

      agent.assertNoPendingInterceptors();

    });

You would need to do change your logic to:

const agent = new MockAgent();

agent.disableNetConnect();

setGlobalDispatcher(agent);

// ...in each test..
const mockAgent = agent.get('https://test.ca');

Thank you for your answer

@mcollina It might be helpful if you can include this in the documentation.
