What is CI? What is its purpose?


Continuous Integration (CI) is a development practice that requires developers to integrate code into a shared repository, each time they make a commitment.

The CI process:

  • Developers check out code into their private workspaces.
  • When they are done with it they commit the changes to the shared repository (Version Control Repository).
  • The CI server monitors the repository and checks out changes when they occur.
  • The CI server then pulls these changes and builds the system and also runs unit and integration tests.
  • The CI server will now inform the team about the successful build.
  • If the build or tests fail, the CI server will alert the team.
  • The team will try to fix the issue at the earliest opportunity.
  • This process keeps on repeating.

Hence, Continuous Integration as a practice forces the developer to integrate their changes every time so as to get early feedback
