People are often given timelines at work that don't include testing. As a believer in agile, I generally push back hard to include testing.
I'd rather dole out incomplete MVP's with tests and fewer features than to skip tests entirely just to hit crazy timelines with a buggy product. Experience says this almost always has positive long term results.
just don't segregate testing, it is integral to the production of quality software and therefore should be considered the same as, say, asking to skip using a keyboard in an attempt to save time.
