Continuous integration what is

Problems detected in an early stage stop the code from progressing further through the pipeline. Detailed results and logs about the failure are immediately sent to the team to fix.

The basic prerequisites for implementing continuous integration include:. CI provides numerous benefits for your software development team including improving developer productivity, automating the development process, improving code quality and software reliability.

The biggest benefit of practicing continuous integration is increased developer productivity. Continuous integration frees developers from manual tasks and the pains of integrating their code with other parts of the system. Instead, they can focus on programming the logic that delivers the features the business needs.

Or they can use the time CI has saved them to invest in professional growth. Continuous integration is a way for your team to automatically build and test every single change in the source code. This is the foundation that enables your broader software delivery process to be efficient, resilient, fast, and secure. The automated testing process can include many different types of checks:.

Building these tests into your CI pipeline, measuring and improving the score in each is a guaranteed way to maintain a high quality of your software. A CI tool provides instant feedback to developers on whether the new code they wrote works, or introduces bugs or regression in quality.

Mistakes caught early on are the easiest to fix. No tool can make developers collaborate in small iterations, maintain an automated build process and write tests.

However, having a reliable CI tool to run the process is crucial for success. Semaphore is designed to enable your organization to build a high-performing, highly available CI process with almost unlimited scale. Semaphore provides support for popular languages on Linux and iOS, with the ability to run any Docker container that you specify.

With the advantages of tight integration with GitHub and ability to model custom pipelines that can communicate with any cloud endpoint, Semaphore is highly flexible. Embracing the serverless computing model, your CI process scales automatically with no time spent on queues. Development teams practicing continuous integration use different techniques to control what features and code are ready for production. Many teams use feature flags , a configuration mechanism to turn features and code on or off at run time.

Features that are still under development are wrapped with feature flags in the code, deployed with the master branch to production, and turned off until they are ready to be used. According to a recent survey , 63 percent of teams that use feature flags report better testing and higher quality software.

Another technique for managing features is version control branching. A branching strategy such as Gitflow is selected to define protocols over how new code is merged into standard branches for development, testing and production. Additional feature branches are created for ones that will take longer development cycles. When the feature is complete, the developers can then merge the changes from feature branches into the primary development branch.

This approach works well, but it can become difficult to manage if there are many features being developed concurrently. The build process itself is then automated by packaging all the software, database, and other components. CI not only packages all the software and database components, but the automation will also execute unit tests and other testing. Teams need to discuss the build schedule that works best for the size of the team, the number of daily commits expected, and other application considerations.

A best practice to ensure that commits and builds are fast, otherwise, it may impede the progress of teams trying to code fast and commit frequently. Automated testing frameworks help quality assurance engineers define, execute, and automate various types of tests that can help development teams know whether a software build passes or fails.

They include functionality tests that are developed at the end of every sprint and aggregated into a regression test for the entire application. These regression tests then inform the team whether a code change failed one or more of the tests developed across all functional areas of the application where there is test coverage. A best practice is to enable and require developers to run all or a subset of regressions tests in their local environments. Open hybrid cloud Support Developers Partners Start a trial.

Continuous Deployment It is closely related to continuous integration and refers to keeping your application deployable at any point. Continuous Delivery It is the discipline of being able to reliably release application changes code at any time. Read more on the topic:. Read the Beginners Guide to Continuous Integration You should focus on setting up a simple continuous integration process as early as possible. Continuous Integration CI vs Continuous Deployment CD If you wish to release your product really fast , you should automate your entire workflow, not just the testing.

What is the best Continuous Integration and Deployment tool or service? How do I choose between them? Hosted vs non-hosted solutions One of the first decisions you have to make is whether you want a hosted Software as a Service SaaS solution or a self-hosted solution. Testing open source vs. Reduces Risk If you test and deploy code more frequently, it will eventually reduce the risk level of the project you are working on as you can detect bugs and code defects earlier. Faster iterations As you release code often, the gap between the application in production and the one the developer is working on will be much smaller.

Faster feedback on business decisions Having a CI process is not only beneficial for software developers, but for their managers as well.
