GitLab CI vs Test Kitchen: What are the differences?
GitLab CI: GitLab integrated CI to test, build and deploy your code. GitLab offers a continuous integration service. If you add a .gitlab-ci.yml file to the root directory of your repository, and configure your GitLab project to use a Runner, then each merge request or push triggers your CI pipeline; Test Kitchen: Integration tool for developing and testing infrastructure code and software on isolated target platforms. Test Kitchen has a static, declarative configuration in a .kitchen.yml file at the root of your project. It is designed to execute isolated code run in pristine environments ensuring that no prior state exists. A plugin architecture gives you the freedom to run your code on any cloud, virtualization, or bare metal resources and allows you to write acceptance criteria in whatever framework you desire.
GitLab CI and Test Kitchen belong to "Continuous Integration" category of the tech stack.
"Robust CI with awesome Docker support" is the top reason why over 16 developers like GitLab CI, while over 3 developers mention "Automated testing" as the leading cause for choosing Test Kitchen.
