RE: Web Development and testing.
What is the ratio of web development to testing. For example, if it took a developer 30 hours to create a screen, approximately how many hours would it take a tester to test it - to include bug fixes. Estimations of course. Is testing one third of the time of developing? Thank you, in advance, for your time.
huh...a third of the hours, eh. What happens in a data driven site when the programmer changes an item in the database or a variable...it might only take that programmer 5 minutes to change but that might change in 30 or 40 different areas which need to be checked out. So does that mean you get 99 seconds to test it. Hopefully not...A lot of the time (not all of the time) I use an inverse, the longer it take a programmer to make changes or build a site, the less percentage of time it will take the tester to test the change or site. As the programmers time to make the change or site is lower then usually the percentage of the tester time is higher.
As far as a ratio of developers to testing, it depends on what you are testing (a large ecommerce site compared to a content management site for instance are going to require a different amount of testers compared to developers) It also depends on the type of testing you do...do you do just functional testing, performance testing, automated testing, etc. (or all of the above) Sorry, I didn't answer your question any better, but depending on the types of apps, the types of testing, the maturity of your company this ratio could be anywhere from 5 developers to 1 tester or 25 developers to 1 tester.
One suggestion, I have is you may want to keep track of the hours that the QA people do put in during a week on testing and get an average amount of work and divide that by a typical week like a 30 hour week(6 hour days because people having meetings or might be trouble shooting something)
