Once you have your testing goals and tools, you need to plan how you will execute your testing. You must consider the scope, the methods, the resources, and the schedule of your testing. For example, what types of testing are relevant and feasible? There are various types such as functional testing, performance testing, usability testing, security testing, and compatibility testing. Additionally, how should you organize your testing? You can opt for manual or automated approaches. Manual testing requires human testers and is more flexible but prone to errors. Automated testing is more accurate but complex and expensive to set up. Furthermore, who should be involved in your testing? You may involve developers, testers, project managers, clients, and users. Each person has a distinct role and perspective that can bring invaluable feedback. You must define roles and responsibilities and communicate with each person throughout the process.
