What is a testing proxy?

Testing Proxies are intermediary servers or tools used during software development and quality assurance to simulate real user environments, monitor network traffic, or control and inspect data exchanges between client and server. They help testers identify bugs, security issues, and performance bottlenecks by allowing the manipulation or analysis of HTTP/S requests and responses. Commonly used in web and mobile app testing, testing proxies support debugging, penetration testing, and ensuring that applications work correctly under various network conditions.
