Travis CI

Travis CI is a continuous integration service that automatically runs tests and builds your code whenever you push changes to your repository. It connects to GitHub, GitLab, and Bitbucket, so your tests can run in the background without manual intervention. The tool supports building applications across multiple platforms and operating systems simultaneously, which is especially useful if you need to ensure your code works on Linux, macOS, and Windows. Once tests pass, Travis CI can deploy your application automatically, reducing the time between writing code and getting it into production. It's designed for development teams of any size, from solo developers to larger organisations.
