Automated vs. Manual Testing

In today's tech world, automation is a buzzword. But when it comes to testing:

• Automated Testing: Useful for repetitive tasks or when you need to test the same thing many times. For example, checking if a login works with thousands of different user details.
• Manual Testing: Ideal for scenarios that need human judgment. Like checking the look and feel of a new website design.

Wrapping Up and Deliverables

After all the testing is done, it's time to wrap things up:

1. Test Reports: Summarizes the results. How many tests were run? How many passed? How many failed?
2. Defect Reports: Details about the problems found, their severity, and status.
3. Feedback and Lessons Learned: What went well? What could be improved? This feedback is invaluable for future projects.

Lastly, always remember that a test plan is a living document. As the project evolves, the test plan might need updates. Regular reviews ensure it remains relevant and effective.
