Test driven development.js

import chai from ('chai').should;

chai.use(chaiHttp);

 describe('it should be able to apdate the article', () => {
      it('should return the 201 status for success update', (done) => {
          const article = {
            title:"kacyiru",
            body:"telecom house"
          }
        chai.request(server)
            .put('/api/v1/article/1')
            .send(article)
            .end((err, res) => {
                  res.should.have.status(201);
              done();
            });
      });

  });

Thanks for the job
But you didn't specify the extension of this file
The test is not complete, please try to add more tests as you tested only the status

Try to use PUT when you are not updating a specific entity

Good job, man!!

But here are one thing you need to change:
1. describe('it should be able to update an article', (req, res) => { you don't need res and req as parameters of the callback in Describe.

• You have only tested the status code. you should also test values of values that are returned.
