I propose to test your site for the correct execution of its functions (Functional Testing) by the user (based on user scenarios), who will visit your site in the future to receive certain services that you will offer on the resource.
After all, as you know, it is better to have the tester find the first defects in the finished product before its release than the future user - this will significantly save the customer's money and nerves in the future.
I have experience in manual testing, took various courses ("ProgKiev", "Udemy", "Stepik", "GoIt"), worked in "GoIt" company (Manual QA Engineer).
After completing the work on the resource, a report will be attached in a spreadsheet format ("Google Docs" or in your bug tracking system - if desired) with a detailed description of the errors found (bug reports).
There will also be offered notes and suggestions for improving or finalizing the general functionality and interface - GUI (if required).
Testing will be carried out on a PC with "Windows 10 pro" (x64) and on the latest version of the one browser you have chosen (“GoogleChrome”, “MozillaFirefox”, “Opera”, “Edge”, “IE”, if necessary).
