AI Agent for Automated Testing
Let AI agents write, run, and fix your tests while you sleep.
The Problem
Writing tests is one of the most time-consuming parts of development. Most teams know they need better coverage, but writing tests manually takes hours away from building features. The result: untested code ships, bugs slip through, and technical debt compounds.
The Solution
Zowl orchestrates AI coding agents to generate comprehensive test suites overnight. Define your testing pipeline once, load your modules, and let agents write unit tests, integration tests, and edge-case coverage while you sleep. Wake up to PRs with passing tests ready to merge.
How It Works
Define a testing pipeline in Zowl's visual editor — specify the agent, test framework, and target modules.
Load your task list: which files or modules need test coverage.
Hit play. Zowl runs your agents overnight, generating tests, running them, and fixing failures automatically.
Wake up to pull requests with new tests, coverage reports, and passing CI checks.
Benefits
Full Coverage Overnight
Go from 30% to 90% test coverage in a single night without writing a line of test code yourself.
Edge Cases Covered
AI agents explore edge cases and boundary conditions that humans often miss during manual test writing.
Framework-Agnostic
Works with Jest, Vitest, Pytest, Go test, or any CLI-based test runner your project uses.
Self-Healing Tests
When a generated test fails, Zowl retries with error context so the agent can fix the issue automatically.
Example Pipeline: Overnight Test Suite
- 1.Agent analyzes src/ directory for untested modules
- 2.Generates unit tests for each module using Jest
- 3.Runs test suite and captures failures
- 4.Retries failed tests with error context
- 5.Opens PR with all passing tests + coverage report
Frequently Asked Questions
Any framework that runs via CLI — Jest, Vitest, Pytest, Go test, RSpec, and more. If it runs in a terminal, Zowl can orchestrate it.
Zowl's pipeline includes a test execution step — only tests that actually pass get included in the PR. You review the output, not debug broken tests.
Zowl includes configurable retry logic. If a test fails, the agent gets the error context and can rewrite the test or skip known flaky scenarios.
