Buildbot is a Python-based continuous integration testing framework.
At its core, Buildbot is a job scheduling system: it queues jobs, executes the jobs when the required resources are available, and reports the results. Buildbot consists of several components: master, worker, www/base, www/console_view, and www/waterfall_view.
This is free and open source software.
Key Features
- Supports not just continuous-integration testing, but automation of complex build systems, application deployment, and management of sophisticated software-release processes.
- Provides the structure and components to automate your build, test, and release processes.
- One or more masters and a collection of workers. The masters monitor source-code repositories for changes, coordinate the activities of the workers, and report results to users and developers. Workers run on a variety of operating systems.
- Configure Buildbot by providing a Python configuration script to the master. This script can be very simple, configuring built-in components, but the full expressive power of Python is available. This allows dynamic generation of configuration, customized components, and anything else you can devise.
