This is a package of actions that you can use in Cypress when writing tests for Mollie (www.mollie.com). It covers easy actions to fill in credit card data, set a payment status and other things on the sandbox pages of Mollie.

Requirements

Your Cypress project needs to be setup correctly to allow cross-domain switching within tests and also your cookies may need to be persisted and configured correctly. Please see this post for more. It will explain everything in detail:

1. Installation

npm i cypress-mollie --save-dev

2. Use Actions and Assertions

Depending on your payment methods, you might need to use different actions and optional assertions.

However, every test needs to start with the MollieSandbox.js and the cookie preparation. Some payment methods will then show a custom screen, such as credit cards, iDEAL and more. If not, or after such a screen, there will always be the payment status page where you can simply use the actions of the PaymentStatusScreen.js.

If you want, there are a couple of prepared assertions for different Mollie features existing. This helps to easily validate credit card forms and more. You don't need to use them of course.

import MollieSandbox from "cypress-mollie/src/actions/MollieSandbox";
import CreditCardScreen from "cypress-mollie/src/actions/screens/CreditCardScreen";
import PaymentStatusScreen from "cypress-mollie/src/actions/screens/PaymentStatusScreen";
import PaymentStatusScreenAssertion from "cypress-mollie/src/actions/assertions/PaymentStatusScreenAssertion";

const mollieSandbox = new MollieSandbox();
const mollieCreditCardScreen = new CreditCardScreen();
const molliePaymentScreen = new PaymentStatusScreen();
const paymentScreenAssertion = new PaymentStatusScreenAssertion();

it('Checkout with Credit Card', () => {

    // ....prepare checkout in your shop where credit card is used.
    // also remember our total amount from our confirm page
    cy.get('.cart-total-value').then((total) => {
        const value = total.text().trim();
        cy.wrap(value).as('totalSum');
    })

    // ....once redirected to Mollie, do the code below:

    // required for the CSRF tokens ;)
    mollieSandbox.initSandboxCookie();

    // if we have a special form such as credit card, iDEAL or more
    // use the corresponding action for that screen
    mollieCreditCardScreen.setCardHolder('Cypress Test');
    mollieCreditCardScreen.setCardNumber('3782 822463 10005');
    mollieCreditCardScreen.setExpiryDate('1245');
    mollieCreditCardScreen.setVerificationCode('1234');
    mollieCreditCardScreen.submitForm();

    // we are now on the final status page
    // if you want, you can assert the total sum
    // that was passed on to Mollie
    cy.get('@totalSum').then(totalSum => {
        paymentScreenAssertion.assertAmount(totalSum);
    });

    // now simply select a status to continue
    // we use "paid" in our case
    molliePaymentScreen.selectPaid();
})

That's it!

You should now be able to easily work with the Mollie sandbox page. If you have troubles with cross-domain navigation in Cypress and Mollie, please see this post: https://boxblinkracer.com/blog/cypress-shopware-mollie
