Continuous integration Concept has evolved since its conception. Originally, a daily build was the standard. Now, the usual rule is for each team member to submit work on a daily (or more frequent) basis and for a build to be conducted with each significant change. When used properly, continuous integration provides various benefits, such as constant feedback on the status of the software. Because CI detects deficiencies early on in development, defects are typically smaller, less complex and easier to resolve.
Continuous Integration has many benefits. A good CI setup speeds up your workflow and encourages the team to push every change without being afraid of breaking anything. There are more benefits to it than just working with a better software release process. Continuous Integration brings great business benefits as well.
1. Manual Tests Are Only a Snapshot
How many times have you heard a team member say “it worked locally.” In their defense, it likely did work locally. However, when they tested it locally they were testing on a snapshot of your code base and by the time they pushed, things changed. Continuous Integration tests your code against the current state of your code base and always in the same (production-like) environment, so you can spot any integration challenges right away.
2. Increase Your Code Coverage
Think your tests cover most of your code? Well, think again. A CI server can check your code for test coverage. Now, every time you commit something new without any tests, you will feel the shame that comes with having your coverage percentage go down because of your changes. Seeing code coverage increase over time is a motivator for the team to write tests.
3. Increase Visibility Across the Team
Continuous Integration inspires transparency and accountability across your team. The results of your tests should be displayed on your build pipeline. If a build passes, that increases the confidence of the team. If it fails, you can easily ask team members to help you determine what may have gone wrong. Just like code review, testing should be a transparent process amongst team members.
4. Deploy Your Code to Production
A CI system can automatically deploy your code to staging or even production if all the tests within a specific branch are green. This is what is formally known as Continuous Deployment. Changes before being merged can be made visible in a dynamic staging environment, and once they are merged these can be deployed directly to a central staging, pre-production, or production environment.
5. Build Stuff Now
All your tests are green and the coverage is good, but you don’t handle code that needs to be deployed? No worries! CI servers can also trigger build and compilation processes that will take care of your needs in no time. No more having to sit in front of your terminal waiting for the build to finish, only to have it fail at the last second. You can run any long-running processes as a part of your CI builds and the CI system will notify you if anything goes wrong, even restarting or triggering certain processes if needed.
6. Build Stuff Faster
With parallel build support, you can split your tests and build processes over different machines (VMs/containers), so the total build time will be much shorter than if you ran it locally. This also means you’ll consume fewer local resources, so you can continue working on something else while the builds run.
7. Never Ship Broken Code
Using continuous integration means that all code is tested and only merged when all tests pass. Therefore, it’s much less likely that your master builds are broken and broken code is shipped to production. In the unlikely event that your master build is broken, let your CI system trigger a warning to all developers: some companies install a little warning light in the office that lights up if this happens!
Why You Need To Learn This Course?
Continuous Integration is widely become the need of every hour in several businesses in the present scenario. The fact is application development has become extremely challenging since last few years. Even after putting a lot of efforts many developing companies and developers are not able to keep up the pace.
