# Cover Pipeline for CI

Integrating Diffblue Cover into a CI pipeline provides the fastest and most comprehensive way to protect your codebase from regressions. Diffblue Cover CLI is triggered by your CI orchestration tool on each pull-request/merge request to:

* Automatically write new unit tests for new code.
* Automatically update existing unit tests in your code.
* Automatically notify about untestable code.
* Automatically make the code testable using Diffblue Cover Refactor.
* Automatically optimize the running of your unit tests with Diffblue Cover Optimize.

Cover Pipeline is completely flexible to fit into your workflow - you can customize how, when, and where Diffblue Cover is triggered so your workflow remains as natural as possible.

## Cover Reports in CI

Cover Pipeline can also automatically Diffblue Cover CLI on a regular basis to generate and upload to Cover Reports.
