In general, how much of a project timescale would you say goes to testing and bug fixing? Roughly.
I've been quoted ~30 days development time for a project that we're having done, but there is an additional 24 days for test and debug. Personally I think that allowing an additional 1/3 of the development time for testing and bug fixing is reasonable (ie an additional 10 days in this case) but nearly doubling the timescale from 30 to 54 days is way too much.
I appreciate that it depends on the project, but what do you guys find? I'm looking for general, rough figures, off the tops of your heads. No need for any evidence to back up any claims. In this particular case it's PHP/MySQL work, but it shouldn't really be relevant.
What do you think?
