A daily build or nightly build is the practice of completing a software build of the latest version of a program, on a daily basis. This is so it can first be compiled to ensure that all required dependencies are present, and possibly tested to show no bugs have been introduced. The daily build is also often publicly available allowing access to the latest features for feedback. In this context, a build is the result of compiling and linking all the files that make up a program. 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.
