Glossary

VibeTester is an AI-powered test case generator for Jira Cloud. It automatically creates test cases in BDD (Cucumber) or step/expected result formats, based on Jira issue fields, additional context, and attachments.

The name VibeTester is inspired by the concept of VibeCoder:

  • VibeCoder represents using AI to generate and accelerate code.

  • VibeTester extends the same idea into the testing domain, enabling teams to automatically generate test cases from requirements.

Together, they reflect the Vibe product family philosophy: applying AI to streamline both development (coding) and quality assurance (testing).
