Which tool is NOT listed as an integration partner for CI/CD servers?

The integration partners for CI/CD servers are typically tools that directly facilitate the continuous integration and continuous deployment processes. Jenkins, Bamboo, and Concourse are all CI/CD tools designed to automate the software development lifecycle, allowing developers to build, test, and deploy applications more efficiently.

Selenium, on the other hand, is primarily a testing framework used for automating web applications for testing purposes. While it is an essential tool in the development pipeline for running automated tests, it does not serve as a CI/CD server itself. Therefore, it is not considered an integration partner in the same sense as the other tools listed, which are specifically designed to manage and orchestrate continuous integration and deployment processes.
