Write API Tests for HTTP PUT Method

Table of Content

Similar to the HTTP POST method, the HTTP PUT method also takes in the request payload but instead of creating a new resource, it lets the user update the existing resource.

The difference between the PUT and POST method is that PUT is idempotent i.e you can keep calling the same request multiple times but it won’t have any side effects, unlike a POST request.

Let’s take a look at an example of a PUT request below –

it('PUT /users/:id', () => {
  // data to update
  const data = {
    status: 'Active',
    name: `Luffy - ${Math.floor(Math.random() * 9999)}`,
  };

  return request
    .put('users/132')
    .set('Authorization', `Bearer ${TOKEN}`)
    .send(data)
    .then((res) => {
      expect(res.body.data).to.deep.include(data);
    });
});

The above code will generate a result similar to this –

{
  code: 200,
  meta: null,
  data: {
    id: 132,
    name: 'Luffy - 7568', // name updated
    status: 'Active', // status updated
    email: 'dharitri_chopra@rogahn.name',
    gender: 'Female',
    created_at: '2020-10-05T03:50:06.247+05:30',
    updated_at: '2020-10-06T00:34:22.958+05:30'
  }
}

There you go, that’s all we need to do to create an API test for the HTTP PUT method. ?
