Learn TRAVIS-CI with Real Code Examples

Travis CI integrates with GitHub to automatically run builds and tests for each commit or pull request.

Supports multiple languages and runtime environments including Python, Java, Ruby, Node.js, Go, and more.

Provides configuration via a `.travis.yml` file stored in the repository.

Automates deployment pipelines to cloud services, package registries, and servers.

Supports both public repositories (free) and private repositories (paid plans).

Automated build and test execution

YAML-based configuration via `.travis.yml`

Build matrices for multi-platform testing

Deployment automation to cloud services

Notifications for build status (email, Slack, etc.)

Build - process of compiling and testing code

Job - single execution unit defined in `.travis.yml`

Stage - logical grouping of jobs for sequential execution

Matrix - configuration for multiple language or environment combinations

Deployment - automatic delivery of artifacts after successful builds

.travis.yml - main CI configuration file

src/ - source code folder

tests/ - test suites

scripts/ - build, test, or deployment scripts

docs/ - documentation and reporting artifacts

Define `.travis.yml` with language, environment, and scripts

Push code to GitHub to trigger build

Monitor job execution and logs via web interface

Add notifications for build results

Configure deployment stages for production or staging

Beginner: single-language build and test

Intermediate: multi-language matrix builds

Advanced: multi-stage pipelines with deployment

Expert: encrypted environment variables and conditional jobs

Enterprise: large-scale pipelines across multiple repositories

Travis CI vs GitHub Actions: simpler vs native GitHub integration

Travis CI vs Jenkins: hosted vs self-managed

Travis CI vs CircleCI: language support and matrix handling

Travis CI vs GitLab CI/CD: GitHub vs GitLab ecosystem

Travis CI vs Drone CI: hosted vs containerized self-hosted pipelines
