Get tests that really run.
Aevrin finds the code a change left untested and writes tests in your project's own style. It runs them, fixes the ones that fail, and gives back only tests that pass and add coverage.

The problem Test Generation solves.
Tests written by a tool often look right and never run, or they run and check nothing. A test that never ran is a guess. A failing test nobody fixed is noise.

Why you can trust what it says.
Run, not just written
Every test runs before you get it. A failing test is fixed or dropped. It is never handed back as if it worked.
Your style
Tests use the framework, layout and style your project already has, so they read like your team wrote them.
Coverage you can see
You see which lines the new tests reach and how much coverage went up, so you can tell useful tests from filler.
The other five checks.
