Tips for continuously running a loop function until retrieving a value from an API within a cypress project

Need help looping a function to retrieve the value from an API in my Cypress project. The goal is to call the API multiple times until we receive the desired value.

let otpValue = '';
const loopFunc = () => {
    cy.request({
      method: 'GET',
      url: 'http://tesurl/api/otp/getotp',
    }).then((res) => {
      expect(res.status).to.equal(200);
      res.body.OTPCode !== null ? (otpValue = res.body.OTPCode) : loopFunc();
      
    });
  };
cy.get('otpinput').type(otpValue)

However, I'm encountering issues with the loop function not functioning as expected. I anticipate that the loop will continue running until we retrieve a non-null value for 'OTPCode'.

Thank you in advance for any assistance.

Answer №1

When working with asynchronous operations in Cypress, it is crucial to handle requests carefully. You can leverage Cypress' retry mechanism along with a custom assertion to ensure that the API response includes a non-null OTP code without resorting to a recursive loop. Below is an illustration of how this can be accomplished:

let otpValue = '';

const getOtp = () => {
  return cy.request({
    method: 'GET',
    url: 'http://testurl/api/otp/getotp',
  });
};

const waitUntilOtpNotNull = () => {
  return getOtp().then((res) => {
    expect(res.status).to.equal(200);

    if (res.body.OTPCode !== null) {
      otpValue = res.body.OTPCode;
    } else {
      // Keep retrying until OTPCode is not null
      cy.wait(1000); // Adjust the wait time as necessary
      waitUntilOtpNotNull();
    }
  });
};

// Implementation
waitUntilOtpNotNull().then(() => {
  // Input the obtained OTP into the designated field
  cy.get('otpinput').type(otpValue);
});
