Testing Management in CI/CD: GitHub Actions vs GitLab CI vs Jenkins with Real Pipelines

These articles analyze CI/CD testing management by comparing GitHub Actions, GitLab CI, Jenkins, CircleCI, and Bitbucket Pipelines. Using a Node.js Express app with Jest and Supertest, the studies evaluate execution speed, dependency caching, and environment execution. The research focuses on optimizing the feedback loop and ensuring automated test suites run on every push. By comparing real pipeline files in a public repository, the analysis examines configuration styles, hosting models, and the impact of execution time on developer velocity.
