Continuous integration (CI) is a software development practice that involves frequently integrating code changes from multiple developers( in your team) into a central repository. Example-Git etc.
How CI Helps:
- This process helps to detect and fix bugs early in the development cycle, leading to faster and more efficient software delivery.
- In the context of software testing, continuous integration refers to the automated testing process that is triggered whenever new code changes are integrated into the main codebase.
- The goal of this process is to ensure that the newly added code does not break the existing functionality of the application.
- Here's an example of how continuous integration works in software testing:
- You can consider the Amazon website or any other e-commerce website.
- Suppose a software development team is working on an e-commerce application that allows users to purchase products online.
- The team uses a continuous integration tool such as Jenkins to automatically build and test the application every time a developer makes a code change and pushes it to the central code repository.
- Whenever a developer makes a code change, Jenkins automatically pulls the latest code from the repository, builds the application, and runs a suite of automated tests to check if the application is still functioning correctly.
- If any of the tests fail, the developer is notified immediately so they can fix the issue before it causes further problems.
Conclusion:
- Continuous integration ensures that any new code changes are thoroughly tested before they are integrated into the main codebase, reducing the likelihood of introducing bugs or breaking existing functionality.
- This helps to improve the quality of the software and accelerates the development process.
