The php|architect blog has posted the second part of Cal Evans' series looking at the typical lifecycle of a project - Development, Testing, Acceptance and Production.
In the previous part of this series, we discussed the main pieces needed for a proper development environment. However, there are other, smaller pieces, scripts, subsystems and other very important components of a properly-configured development environment that donâ€™t fit in the acronym.
This second part of the series looks at the "T" in DTAP - testing. It mentions unit testing, integration testing and regression testing. He also touches briefly on "refresh scripts" to handle data updates or pushes out to another stage of the process.
