Review Bot

Review Bot is a tool for automating tasks on code uploaded to Review Board, and posting the results as a code review. Review Bot was built to automate the execution of static analysis tools.

Review Bot is:

  • 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.
  • Scalable: Review Bot is built using Celery and can scale out to service very large Review Board instances.
  • Integrated Configuration: Tools are configured through the Review Board admin panel, including settings uniquely defined for each task.

Supported Code Checking Tools

Review Bot can perform automated code reviews using any of the following tools:

  • BuildBot "try" - Builds the patch in a configured BuildBot environment
  • checkstyle - A static analysis tool that provides a variety of checkers for Java code
  • Cppcheck - A static analysis tool for C/C++ code
  • CppLint - Checks C++ code against Google's style guide
  • doc8 - Check ReStructuredText documentation for styling and syntax errors.
  • flake8 - A wrapper around several Python code quality tools
  • PMD - A static analysis tool that provides checkers for many languages
  • pycodestyle - A code style checker for Python code
  • pydocstyle - A static analysis tool for Python docstring conventions
  • pyflakes - A static analysis tool for Python code
