Our engagement

When our QA engineers joined the project, there was only one QA engineer managing a simple QA flow based solely on ticket verification. The DeviQA team initiated the creation of initial test documentation and integrated regression testing and smoke testing into the QA workflow, enabling the client to release a stable application.

Another challenge we encountered at the very beginning was the inefficient management of tasks and activities on the existing Jira board. Our team helped create an appropriate task-managing process that gave the team a quick understanding of project progress.

Our QA engineers also came up with a complex approach to payment testing, which let the team detect a lot of payment-related bugs in the staging environment. Instead of changing the order status to ‘paid’ via the admin panel, they simulate real payments. This was implemented using sandbox solutions of payment systems that had been integrated into the product, such as Stripe test mode and Bitcoin Testnet Wallet by BitPay.

By structuring the QA process and creating the test documentation, we substantially improved the quality of releases and enabled the client to clearly define how much time was needed to prepare a releasable build. Moreover, our work eliminated the need to keep the whole development team in place during releases to fix unexpected defects.

Services provided

Web Testing

The team achieved comprehensive test coverage by thoroughly testing various critical components of the application. Approximately 75% of the functionality was covered with test cases. The payment and subscription systems were tested with the help of BitPay Testnet Wallet (crypto payments) and Stripe’s test mode (bank payments). Also, we successfully identified and addressed user interface issues through meticulous usability testing and feedback analysis.

Mobile Testing

Some members of the team were involved in testing and releasing four mobile apps for Android and iOS. This was a separate project related to products available on Shops. The team tested the mobile versions of Shops on a variety of real mobile devices and emulators.

Dedicated QA Team

Our two manual testers integrated seamlessly into the client's team, which already included a QA engineer from another contractor. Their responsibilities encompassed feature verification, test case maintenance, test documentation design, and the execution of smoke and regression tests. Additionally, each QA engineer contributed to other subprojects related to developing mobile apps for digital products available on Shops, a streaming platform, and a clothing store.
