Hello! I need help on one topic. I've red a lot of articles on different types of testing, but i still don't understand how is it implemented in real life. Is it done by one tester or by group, for example functional testing done by one person and load by another. And also how long is it usually take to test client/server application. Do you have to do all types of testing in regression testing. And what is usual day in software testing environment. Thank you and any answer will be greatly appreciated.
