How to write assertion for REST module ?

Feature('Api');
Scenario('test something', (I) => {
  I.sendGetRequest('/styles/123').then((response) => {
      response.status.should.eql(200);
      response.data.styleId.should.eql('123');
   });
});

I got :

(node:8692) UnhandledPromiseRejectionWarning: TypeError: **Cannot read property 'eql' of undefined**

Should i require some package ?

I try to reproduce the tests here : https://github.com/Codeception/CodeceptJS/blob/master/test/rest/REST_test.js#L42

Yes, you should init should :)

require('chai').should();

and install chai package

 I.sendGetRequest('/api').then((response) => {
    response.status.should.eql(200);    
    assert.equal(200, response.status);
  });

@DavertMik

If response status is not 200, it output an error but the test is OK - passed (tried should and assert)

Do you know this issue ?

Here is how i've done, we are missing I.seeResponseContainsJson, seeResponseIsJson ... methods like in codeception REST module

Feature('Api feature');

require('chai').should();

Scenario('test a GET request', async (I) => {
  response = await I.sendGetRequest('/api');
  //output : console.log(response.data);
  response.status.should.eql(200);
  //check json object
  response.data.should.be.an('object');
  //check property present
  response.data.should.have.property('operationId');
  //check property value
  response.data.operationId.should.eql('1123231');
  //check partial json
  response.data.should.deep.include({
    "operationId": "1123231",
    "calculationId": "2"
  });
  //check full json
  response.data.should.eql({
    "operationId": "1123231",
    "calculationId": "2",
    "applicationDate": "2017-05-23",
    "typeCode": "SU"
  });
});
