Increase test coverage fast
Have a coverage gap to close before a release or review? Generate meaningful tests for untested code quickly — not filler that games the metric.
Coverage numbers are easy to game with tests that execute code without asserting anything useful — and that is exactly the temptation when a CI gate blocks a release. Those tests raise the percentage while catching no bugs.
This tool writes meaningful tests for your untested functions: real assertions on real behavior, including the edge cases that justify the coverage. You close the gap honestly, ending up with a suite that protects against regressions rather than one that just turns the bar green.
The tool for this
🧪Unit Test Generator
Generate a thorough unit-test suite — happy path, edge cases and error paths.
Frequently asked questions
Will these be real tests or filler? +
Real ones — they assert on behavior and include edge cases, so coverage reflects genuine protection rather than executed-but-unchecked lines.
Can I target specific uncovered functions? +
Yes. Paste the functions lacking coverage and it focuses the suite there.
Does it fit my CI setup? +
It writes tests in your framework, so they slot into your existing CI without changes.
