Prepare a test plan for a corporate website, what is needed for this?

Question

Software testing

I came to practice in a company that develops websites (mostly 1C-Bitrix) there are no testers here, I was offered to help them with creating a test plan for the company's projects.
Maybe there are people who can tell you where to go and what to read / study? At least in general terms.

Answer 1

Run away from there and from Bitrix in general :)

Answer 2

Suggest to your management to use the services of a third-party company. I can advise a1qa, this may suit you www.a1qa.ru/services/full-cycle-testing
