1. I'm currently testing a web application that has 300+ test cases. I'm doing manual validation only. How to prioritize them and to make sure I'm covering 100%?
2. I'm also validating the reports page where I need to compare the data with the UI vs. its files that I download (CSV, Excel, PDF). Also, the table report has chart representation which I have to verify, its UI vs. downloadable files (JPEG/PDF/PNG/PDF). I would like to know how to cover all the scenarios or the strategy to be followed.
