The project, hosted on GitHub with documentation at utsab345.github.io/stepfork, is seeking testers working on LLM applications, tool-using agents, and agent workflows, with the developer asking specifically how reliably replay reproduces failures and whether the generated regression tests are meaningful.", "body_md": "Hi everyone,\n\nI’ve been building **Stepfork**, an open-source tool to make AI-agent failures easier to reproduce and test.\n\nWhen developing AI agents, debugging a failed execution can be difficult. Even after fixing a bug, it’s easy for the same issue to return without regression tests.\n\nStepfork aims to help by letting developers:\n\nRecord AI-agent executions.\n\nReplay recorded failures offline.\n\nGenerate pytest regression tests from recorded runs.\n\n**Project links**\n\nGitHub: [GitHub - utsab345/stepfork: Open-source Python toolkit to record and replay AI agent executions, detect regressions, and turn failures into reproducible pytest tests. · GitHub](https://github.com/utsab345/stepfork)\n\nDocumentation: [Stepfork](https://utsab345.github.io/stepfork/)\n\nI’m looking for developers working on LLM applications, tool-using agents, and agent workflows to try it and share feedback.\n\nI’d particularly appreciate feedback on:\n\nHow useful is record-and-replay testing for your agent development workflow?\n\nHow reliably does the replay process reproduce failures?\n\nAre the generated regression tests meaningful, or do they risk merely reproducing the original run?\n\nWhat integrations or features would make Stepfork more useful?\n\nThe project is still evolving, and I’d welcome critical feedback, bug reports, and suggestions.\n\nThanks for taking a look!", "url": "https://wpnews.pro/news/looking-for-feedback-and-testers-for-stepfork-an-open-source-ai-agent-testing", "canonical_source": "https://discuss.huggingface.co/t/looking-for-feedback-and-testers-for-stepfork-an-open-source-ai-agent-testing-tool/190668#post_1", "published_at": "2026-10-16 10:08:29+00:00", "updated_at": "2026-10-16 10:45:42.235338+00:00", "lang": "en", "topics": ["ai-agents", "developer-tools", "ai-tools", "mlops", "artificial-intelligence"], "entities": ["Stepfork", "Utsab345", "GitHub", "pytest"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/looking-for-feedback-and-testers-for-stepfork-an-open-source-ai-agent-testing", "markdown": "https://wpnews.pro/news/looking-for-feedback-and-testers-for-stepfork-an-open-source-ai-agent-testing.md", "text": "https://wpnews.pro/news/looking-for-feedback-and-testers-for-stepfork-an-open-source-ai-agent-testing.txt", "jsonld": "https://wpnews.pro/news/looking-for-feedback-and-testers-for-stepfork-an-open-source-ai-agent-testing.jsonld"}}
