Review Bot Documentation¶
Welcome to Review Bot!
Review Bot automates parts of the code review process, using a wide range of industry-standard code checking tools to look over your code and catch problems so your developers can focus on the bigger picture.
Made for Review Board: Tools are configured through Review Board’s existing Integrations functionality, letting you choose exactly when and how tools are run within your organization.
Scalable: Review Bot is built using Celery and can scale out to service very large Review Board deployments.
Extensible: Writing plugins is simple using a convenient API to retrieve code files and craft a review. If more power is needed, tools can access the full Review Board API.
Premium support for Review Bot is included with any Review Board support contract.
Review Bot 3.1 supports Review Board 3.0 or 4.0, and Python 2.7 or 3.6 through 3.10.
A Review Bot setup consists of three pieces:
The Review Bot extension for Review Board.
A message broker (such as RabbitMQ).
At least one Review Bot worker (either on the Review Board server or somewhere else in your network), which will run the code checking tools.
There are two official ways to install Review Bot:
Once Review Bot is installed, you’ll need to configure the extension and the workers:
