Travis CI is a hosted continuous integration service used to build and test software projects hosted on GitHub and Bitbucket. As one of the first CI/CD platforms to integrate with GitHub, Travis CI has become popular among open-source projects and early-stage startups for its straightforward setup and use. It automates the process of testing code changes in real time, providing immediate feedback on the success of those changes, and can automatically deploy code to various environments.
Continuous Integration is a mode of work where multiple programmers can integrate changes continuously into the same code.
The foundation of successful collaboration lies in the agreement on facts, while the key to achieving development velocity is through conducting experiments in the form of tests to validate the code's functionality.
Continuous Integration facilitates both of these processes by creating two distinct processes:
- The first process allows developers to agree on the "true" codebase, commonly called the master branch or trunk.
- The second process validates the codebase after changes are made using tests.
For startups, it is crucial to have processes in place that enable collaboration, and enhance the delivery of changes in a consistent, predictable, and safe manner. This is typically achieved by running automated tests after the introduction of a change into a Git branch or after creating a Pull-Request. If the tests fail or if the branch is not up-to-date with the latest changes from the main branch, the change to the code cannot be introduced to the main version of the code. Such measures ensure that non-working changes are not introduced into the main branch, instilling confidence in introducing changes to the system.
Our experience with Travis CI helped us build repeatable CI/CD patterns, templates, and operational runbooks that we use to improve delivery speed and reliability for client teams across different stacks and repository setups.
Some of the things we did include:
This experience helped us accumulate significant knowledge across multiple Travis CI use-cases—from basic build validation to secure multi-environment delivery—and enables us to deliver high-quality Travis CI setups that are maintainable, observable, and aligned with how teams actually ship software.
