It was necessary to integrate the website with different payment systems and support multiple browsers and devices. A big flow of clients was expected that’s why the system should be able to withstand a high level of load, especially during promo-events and sales. It should also support a big shop catalogue.

Cross browser testing detected critical and average errors, which reduced the negative experience by users in different environments.
