See the difference

Send code to @vustbot, name your framework, and get happy-path, edge-case and error tests to review and run.

Pure function

You paste

A function with a few branches.

You get

Tests covering the happy path, edge inputs and error paths, in your framework — adapt and run.

Before a refactor

You paste

Code you are about to change.

You get

Tests that capture current behavior so the refactor stays safe.

02·Practical use cases

Who generates tests with AI

Devs

Get a test scaffold for a function fast

Paste the function, get cases (happy path, edges, errors) to adapt.

Learners

See how to test a piece of code

Example tests in your framework, explained.

Refactorers

Add a safety net before changing code

Tests that capture current behavior so refactors stay safe.

03·How it works

How test generation works here

01Paste the function

Open @vustbot, paste the code, and name your framework (Jest, pytest, JUnit…).

02Get test cases

Happy path, edge cases, and error paths as runnable tests in your framework.

03Refine coverage

Ask for more edge cases, mocks, or a different style — in the same chat.

05·Quality & trust

Test generation, honestly

A scaffold, not a guarantee

@vustbot writes plausible tests from the code you paste — review them and run them. It doesn't execute your suite or measure real coverage.

Name your framework

Say which test framework and style you use so the output drops in cleanly.
