How can we avoid CI?
Continuous Integration: 5 Tips to Avoid “Integration Hell” Commit Code Frequently. CI works best when making frequent small, incremental changes to the application. … Fix Broken Builds Immediately. … Split the Code: Feature Branches. … Rely on Automation. … Use Feature Toggles.
What is continuous integration and continuous delivery?
Continuous Integration happens before you build as you are testing code. Delivery means you can release something to the staging environment or the pre-production environment. Continuous Delivery is when your code is always ready to be released but isn’t pushed to production unless you make the decision to do so.
What’s the main purpose of continuous integration?
Continuous Integration (CI) is a development practice that requires developers to integrate code into a shared repository several times a day. Each check-in is then verified by an automated build, allowing teams to detect problems early.
What problem does continuous integration solve?
Continuous Integration or CI allows multiple development teams to work in tandem and easily incorporate new and improved features to meet the evolving needs of the market. By integrating the efforts of developers frequently, CI results in faster feedback loops, early discovery of bugs, and improved quality of products.
Why your tests may pass locally but fails in Jenkins?
Since the Jenkins machine/VM/pod/container is likely running different (slower) hardware than your local machine, tests dealing with multiple threads or inadvertent race conditions may run differently and fail in Jenkins.

What is the critical success factor while adopting continuous integration?
Teams leveraging continuous integration prove the full lifecycle as frequently as possible. They develop, test, integrate, and deploy every time they build. The more frequently you perform all software lifecycle activities, the less likely it is that unforeseen high risk issues will surface unexpectedly.
