Continuous Integration

Developers practicing continuous integration merge their changes back to the main branch as often as possible. The developer’s changes are validated by creating a build and running automated tests against the build. By doing so, you avoid the integration hell that usually happens when people wait for release day to merge their changes into the release branch.

Continuous integration puts a great emphasis on testing automation to check that the application is not broken whenever new commits are integrated into the main branch.

Benefits of pull requests

  • Use this collaborative platform to discuss potential modifications to the code.
  • Improve code quality.
  • Simplify the process of receiving feedback from the reviewer.
  • Address feedback easily in-line near the relevant code.
  • Provide better stability for the code.
