The practice of beta testing has gained traction and popularity, especially with the emergence of SaaS tools that facilitate the process. However, many beta programs commit common mistakes, such as not defining a clear plan or recruiting testers who don't represent the target audience. Rushing QA testing, recruiting too few or too many testers, ignoring usability bugs, and using the wrong tools for the job are also pitfalls to avoid. Additionally, it's essential to define and track metrics, educate beta testers, engage with them, and use the right tool for the job to ensure a successful beta test. Tools like Instabug can help streamline the process and provide valuable insights into app performance and user feedback.
