After you have planned your testing strategy, you need to implement your testing methods. This involves executing your testing activities, collecting your testing data, and reporting your testing results. You need to use the appropriate testing methods for your testing goals, such as unit testing, integration testing, system testing, regression testing, smoke testing, load testing, stress testing, usability testing, beta testing, or A/B testing. You also need to use the suitable testing tools for your testing methods, such as debuggers, emulators, simulators, analyzers, monitors, or feedback platforms. Additionally, you need to use the effective testing techniques for your testing tools, such as manual testing, automated testing, exploratory testing, scripted testing, or heuristic testing.
