Regression test generation

Problem

Developers change code but don't always write regression tests. Existing test suites miss edge cases introduced by new changes, and bugs reach production.

Solution

The AI agent analyzes the diff in each PR, identifies affected code paths and dependencies, and generates regression tests targeting the specific areas at risk. Tests run in CI before merge.

Benefits

• Regression coverage for every code change
• Tests target the specific areas at risk
• Runs automatically in CI/CD pipeline
• Catches regressions before they reach production

How to get started

1. 1

   Connect to your repository

   Install the agent in your GitHub or GitLab repo. It monitors PRs and analyzes diffs.

2. 2

   Configure test framework

   Set your testing framework, conventions, and which directories to cover.

3. 3

   Review generated tests

   The agent generates regression tests per PR. Review, adjust, and merge alongside the feature code.
