. The use of such disciplined procedures as daily builds is particularly necessary in large organizations where many programmers are working on a single piece of software. Performing daily builds helps ensure that developers can work knowing with reasonable certainty that any new bugs that show up are a result of their own work done within the last day. Daily builds typically include a set of tests, sometimes called a " smoke test." These tests are included to assist in determining what may have been broken by the changes included in the latest build. The critical piece of this process is to include new and revised tests as the project progresses.

Continuous integration builds

Although daily builds were considered a best practice of software development in the 1990s, they have now been superseded. Continuous integration is now run on an almost continual basis, with a typical cycle time of around 20-30 minutes since the last change to the source code. Continuous integration servers continually monitor the

. When these servers detect new changes, they use a build tool to rebuild the software. Good practice today is also to use continuous integration as part of
