radish-bdd
Behaviour-Driven-Development tool for Python
Decision gist · record as of 2026-08-14
Yes, if you need a Python-native BDD framework. radish is actively maintained, has no known vulnerabilities, low install friction, and works across major platforms and recent Python versions. It's mature (since 2013) and suitable for teams wanting to write acceptance tests in Gherkin. Choose it if you prefer a Python-focused alternative to tools like Behave or Cucumber.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3 or later (supports 3.7 through 3.14); feature files and step definitions must follow Gherkin conventions.
- Low friction install with five runtime dependencies (docopt, colorful, tag-expressions, parse_type, humanize).
- Actively maintained with recent commits and no known vulnerabilities.

What it is and what it does
radish is a Python-based BDD framework that reads and executes Gherkin feature files—the human-readable test specifications used across the BDD ecosystem. It parses Given-When-Then scenarios and maps them to Python step definitions you write, then runs them and reports results. Beyond standard Gherkin, radish adds preconditions, scenario loops, constants, and expression support, giving you more flexibility in how you structure tests.
You install it via pip, write feature files in plain Gherkin syntax, define step implementations as decorated Python functions, and invoke the radish command-line tool to run your test suite. It works on Windows, Mac, and Linux, supports Python versions from 3.7 onward, and depends on a small set of utilities for command parsing, colored output, tag filtering, type parsing, and human-readable formatting.
Use it for
- Write acceptance tests in plain English (Gherkin) that non-technical stakeholders can read and understand.
- Automate API or web application testing by mapping feature scenarios to Python step definitions.
- Build test suites with reusable steps and data-driven scenarios using scenario loops and constants.
- Integrate BDD tests into CI/CD pipelines to verify behavior before deployment.
- Document system behavior through executable feature files that stay in sync with actual code.
