Ways to validate an element in an Array using Cypress dynamically

I have a question regarding the dynamic verification of Array elements. For my project, I need to suggest a price that will increase over time, and I require a script that can verify these elements dynamically. In the screenshot provided, you can see what needs to be verified. The script I used is as follows:

    ` describe('POST method', () => {
    it('suggest a price', () => {
     //Suggest a price you are willing to pay. Available only for auctionType: fixed_price

        cy.request({
            method: 'POST',
            url:"xxxxxx",

            headers:{
                "Authorization":"LOOL",
                "content-type": "application/json"
            },

            body: {
                "id": "d42f516a867590633dd8a82cb2563437",
                "bid": 6900,
                "auctionPlatformId": "xxx",
                "auctionPlatformUserId": 0
            },

            failOnStatusCode: false

            
        })


expect(res.status).to.eq(200)
      expect(res.body).to.have.property("id", "d42f516a867590633dd8a82cb2563437")
      expect(res.body).to.have.property("amount", 6900)
      expect(res.body).to.have.property("auctionPlatformId", "abc")
     expect(res.body).to.have.property("auctionPlatformId", 0)`

However, this code lacks dynamism and does not perform the required verifications.

Answer №1

Using the within method and defining a range is one approach.

expect(res.body.amount).to.be.within(6000,7000)

To generate random bid values, you can utilize Math.random

"bid": Math.floor( Math.random() * 10000 ) + 1  //Generate random numbers between 1 and 10000

If all amounts in the response are expected to be less than or equal to the input bid amount, you can implement the following strategy. Define minimum and maximum values for the random bid amount and then assert that the response body's numbers fall within this range.

describe("POST method", () => {
  it("suggest a price", () => {
    //Suggest a price you are willing to pay. Available only for auctionType: fixed_price
    var minval = 1
    var maxval = 10000
    var bidAmount = Math.floor(Math.random() * maxval) + minval
    cy.request({
      method: "POST",
      url: "xxxxxx",

      headers: {
        Authorization: "LOOL",
        "content-type": "application/json",
      },

      body: {
        id: "d42f516a867590633dd8a82cb2563437",
        bid: bidAmount,
        auctionPlatformId: "xxx",
        auctionPlatformUserId: 0,
      },

      failOnStatusCode: false,
    }).then((res) => {
      expect(res.status).to.eq(200)
      //Assert individually if needed
      expect(res.body.suggestedPrices[0].amount).to.be.within(minval, maxval)
      expect(res.body.suggestedPrices[1].amount).to.be.within(minval, maxval)
      expect(res.body.suggestedPrices[2].amount).to.be.within(minval, maxval)

      //Assert all together in a loop
      for (var index in res.body.suggestedPrices) {
        expect(res.body.suggestedPrices[index].amount).to.be.within(
          minval,
          maxval
        )
      }
    })
  })
})

        )
      }
    })
  })
})
