In the past ten years , Continuous integration （Continuous Integration,CI） And continuous delivery （Continuous Delivery,CD） Great progress has been made in the field .DevOps The rise of testing has led to CI/CD The rapid demand for tools . Existing solutions always improve over time , A large number of new products or versions are entering QA field . When you have so many options on hand , Choosing the right tool can be a bit of a challenge .
In all the optional tests CI/CD In the tools ,Jenkins and GitLab CI/CD Two tools you should definitely consider .Jenkins stay GitHub There are 16,000+ give the thumbs-up , and GitLab CI/CD Yes 2012 Like .Jenkins My favorite number is GitLab CI/CD I like it a lot 8 More than double .
However , These numbers are not about choosing one CI/CD The only thing you need to see when using tools . It's also despite the huge gap in likes ,Jenkins vs GitLab CI/CD There is also fierce competition on multiple accreditation platforms . With G2 For example ,Jenkins stay G2 The average score is 4.3 star , Yes 288 comments ;GitLab CI/CD stay G2 The average score on is 4.4 star , Yes 270 comments . so to speak ,Jenkins vs GitLab CI/CD It's a close competition . Interestingly ,Jenkins Is in 2011 Published in , And in CI/CD Business , It has always been the first choice for testers . However , since 2014 Since its release ,GitLab CI/CD It has always been at the top of the list with its cutting-edge features . When we published this article , There was a poll on social media .
Another tool most mentioned is GitLab CI/CD. As a DevOps Testing experts , You need to be based on your own project 、 To scrutinize these budgets and other tools . To help you , I will be right Jenkins vs GitLab CI/CD Make an in-depth assessment , Help you determine the right CI/CD Tools to meet your project needs .
1. Jenkins Introduce
