Cypress - get value from json response body

rated 0 times [ 1] [ 6] / answers: 1 / hits: 43234 / 4 Years ago, sun, february 2, 2020, 12:00:00

I'm using Cypress to do some API testing, but I am struggling to access values in the JSON response body; however I can perform assertions against the body which suggests it's receiving it correctly.

Below I am trying to assign the JSON body (response.body) and then get the value of 'id' out of it:

describe('Creating a board', () => {    

it('should create a board', () => {

    cy.request({

    method : 'POST',

    url:`${requestUrl}/boards/`, 

    qs: {

      name : test-board,

      token : token,

      key : key

    }

    }).then((response) => {

      expect(response).property('status').to.equal(200)

      expect(response.body).property('id').to.not.be.oneOf([null, ])

      const body = (response.body)

      boardId = body['id']

    })

})

I've done numerous searches and can't find a concrete way to do it. Any help would be appreciated...

I managed to solve this by using a Promise;

Doing some further reading, I found out the then function I am executing is synchronous (I'm new to JS, pls don't hurt me).

I refactored the then function to the following:

.then((response) => {

        return new Promise(resolve => {        

            expect(response).property('status').to.equal(200)

            expect(response.body).property('id').to.not.be.oneOf([null, ])

            const respBody = response.body;

            boardId = respBody['id']

            resolve(boardId)

        })

It's probably not entirely correct or best practice, but it will do for my demo
