APIs and mobile applications present unique testing challenges that require specialized knowledge and tooling. This category covers both domains in depth – from API testing fundamentals and microservices architecture validation to mobile automation with Appium and cross-platform testing strategies. These are among the most in-demand skills for QA engineers today.
On the API side, you will find comprehensive guides covering test design, architecture-specific patterns for microservices, and practical comparisons of modern API testing tools. The mobile testing articles address the complexities of device fragmentation, platform differences, and cloud-based device labs.
Whether you are testing a REST API, validating GraphQL endpoints, or automating mobile workflows across iOS and Android, these articles provide the depth and practical detail needed to do the job well. – Yuri Kan, Senior QA Lead
