What We Actually Use

In our experience, we primarily use CodeGuru for Java projects and HoundCI for general coding standards across various languages. Sourcery is our go-to for Python projects due to its specific focus.

Step-by-Step: Automating Code Reviews

1. Choose Your Tool

Based on your project needs, select one of the tools mentioned above.

2. Install the Tool

For tools like CodeGuru or Sourcery, installation involves:

• Adding the tool to your GitHub or GitLab repository.
• Configuring necessary permissions.

3. Set Up Code Review Rules

Define the coding standards and rules you want the AI to check against. Most tools offer templates to get you started.

4. Trigger Your First Review

Create a pull request in your repository, and the AI will automatically analyze the code based on the rules you've set.

5. Review the Feedback

Once the analysis is complete, review the feedback provided by the AI. Most tools will highlight issues and offer suggestions for improvement.

6. Implement Changes

Make the necessary changes based on the AI's feedback and push the updates to your repository.

Expected Outputs

After following these steps, you should see a detailed report from the AI tool, outlining any issues and suggestions for improvement.

What Could Go Wrong

• Integration Issues: Sometimes, the tool may not integrate well with your existing workflow. Ensure you check compatibility.
• False Positives: AI isn't perfect; you may get suggestions that don't apply. Always review suggestions critically.

What’s Next?

After setting up your automated code reviews, consider integrating CI/CD tools to streamline your deployment process further. Look into tools like CircleCI or Travis CI for continuous integration.

Conclusion: Start Here

For those just getting started with automating code reviews, I'd recommend CodeGuru for Java projects or Sourcery for Python. These tools have proven effective in our own work, and they won't break the bank.

Automation can save you significant time, allowing you to focus on building your product rather than getting bogged down in manual reviews.
