Internal Developer Platforms like Humanitec enable self-service for developers, allowing them to manage internal applications, pipelines, and deployment infrastructure. QA engineers benefit from working with IDPs by having a unified platform API that provides insights into the state of deployed applications, making it easier to identify issues and optimize testing. QAs can develop custom views and applications on top of the Platform API, reducing context switching and cognitive load, and enabling them to focus on what they need to observe. An IDP does not restrict QA engineers but rather provides an additional layer that enables them to have a more focused view and easier access to information, ultimately improving their efficiency and productivity.
