Ensuring Quality and Reliability for Marketplace API

Challenge

• Complex API structure. The API system was extensive, with numerous endpoints and dynamic data, requiring comprehensive understanding and efficient testing within a tight timeframe.
• Real-time data updates. Ensuring that real-time data updates were accurately reflected on the client side was a significant challenge.
• Billing and user flow. Verifying the functionality of billing plans, including activation, special conditions, payments, deactivation, and overdue payments, added another layer of complexity.
• New features to test. Just before the release, the client was finalizing new features and pop-ups for premium accounts, necessitating thorough UX/UI testing.

Solutions

We assembled a dedicated team for the job: 5 professionals, including 4 manual QA and a part-time Team Lead, all with a deep understanding of API testing and dynamic data environments.

Our collaboration with the development team was crucial. More than just running tests, we actively reviewed requirements, scrutinized test cases, and identified defects.

Our comprehensive testing strategy included:

• Functional testing. We verified that all data was displayed correctly across the client’s sites. We manipulated the database to simulate dynamic data changes and checked real-time updates.
• API testing. We conducted specific API testing, checking the availability and functionality of each endpoint.
• Billing and user flow testing. We tested billing plans and various user scenarios using test accounts.
• UI/UX testing. We focused on the new features and pop-ups for premium accounts, ensuring a smooth and user-friendly experience.

With a solid team and a clear strategy, we managed to cover over 500 test cases. We used tools like Postman for API testing, which helped us identify several serious bugs.
