Kerno

Testing Co-Pilot for Backend Engineers

Software Engineering
Developer Tools
Artificial Intelligence

Never manually write, or and maintain backend tests again! Kerno automates integration testing end-to-end inside your IDE. It understands your codebase, generates meaningful tests, spins up test environments, executes tests, and delivers instant audit reports to catch issues early, validate changes before committing your code. Use Kerno to: → Catch breaking changes at source → Augment current Code-Gen loops with test data → Audit AI generated code in real-time → Increase test coverage

Hey PH 👋

Firstly, we want to say sorry to all the developers who enjoy writing, running and maintaining tests. 😅

Manual Integration Testing is an antipattern in AI native workflows.
While AI is helpful to do rapid prototyping or boilerplate tasks, we still do not trust it to do the most crucial parts of coding without testing or audits. Code generation moves at speed, but testing and auditing are still slow, manual, inconsistent, and even then, the feedback cycle from issue to fix takes hours.

The New Era of Testing
Kerno AI fully accelerates the entire workflow for integration testing, providing an audit of behavior changes introduced by new and AI generated code, in seconds, without leaving the IDE.

Developers use Kerno to:
→ Catch breaking changes at source
→ Augment current Code Gen loops with test data
→ Audit AI generated code in real time
→ Increase test coverage

Testing Should be an Experience Designed to Flow
✅ IDE native – Run tests inside your IDE and get results in seconds without waiting on CI.

✅ Context aware test generation – Kerno creates a detailed graph mapping every piece of code, dependency and business logic to understand how everything fits together and generate high quality tests.

✅ Test execution – When you make a code change, Kerno autonomously spins up real dependencies, runs, and updates tests, and detects behavioural and logical changes in your app.

✅ Maintenance – As your codebase evolves, Kerno automatically self-heals, adds and remove tests to ensuring your test suite never drifts out of sync.

You spec. AI Builds. Kerno Validates. Ship software with confidence.

Comment highlights

Congratulations on the launch! Before AI appeared, many people skimped on test development.

Spent too many mornings chasing flaky API tests and waiting on CI. If Kerno can spin up deps in-IDE and self-heal, that’d be nice. Gonna try it on a small Go service first. Curious how it handles messy legacy DB schemas.

My microservices architecture looks less like a map and more like a crime scene right now.

If Kerno can actually untangle the relationships between my legacy code and the AI agents trying to fix it, that's witchcraft.

Technical Q: How much overhead does the agent/telemetry add? I’m paranoid about observability tools slowing down the very thing they are supposed to be watching. (We have to be super light with our own tracking at SquarePact, so I feel the pain). Congrats on the launch @karim_traiaia!
