Quality Assurance (QA) plays a vital role in the development of the web and mobile applications, but many overlook the critical nature of this piece of the app development process. To ensure the success of an app, QA must be involved in all stages of development, from creating the concept, analyzing requirements and wishes, creating test specifications, testing early versions of the app, releasing the finished product, to the post-development review process. And, here at 4Bell Technology, we bring some key differentiators to ensure a sound mobile quality practice. These are centered around a robust infrastructure, a strong tool ecosystem and a brilliant, well thought out approach and methodology. Our app development services include full QA on multiple devices, in multiple environments. We conduct extensive mobile app testing throughout the entire development cycle, including manual testing, visual QA, and automated testing to ensure that your application functions perfectly and delights users. Our approach typically includes the following aspects: Manual testing by in-house test engineers Automated testing Full visual QA QA consulting Integrated testing process that spans the full development cycle Our agile process allows us to test, locate, and fix issues that arise throughout the project lifecycle. Using a combination of manual and automated testing, we thoroughly test all use cases, problematic edge cases, and all visual and functional aspects.
