How does this integrate with TDD?

The skill provides a structured approach for the Red phase of TDD, helping you write behavioral scenarios and identify test requirements before any implementation code is written.

When should I use the Gherkin Scenario Architect?

Use it whenever you are writing new features, defining acceptance criteria for stories, or planning test strategies where you need to ensure observable results are verified.

What makes a 'behavioral' Gherkin scenario?

A behavioral scenario tests the actual execution and outcome of a feature—such as verifying a file was created with correct data—rather than just checking if a function name exists in the source code using tools like grep.

Does this skill help determine when integration tests are needed?

Yes, it specifically identifies when features like process spawning, file system changes, or state persistence require integration tests instead of just isolated unit tests.

Security & Testing

Generates behavioral Gherkin scenarios and acceptance criteria focused on observable outcomes to ensure robust, bug-resistant test coverage.

About

This skill empowers developers to write high-quality Gherkin scenarios that prioritize behavioral verification over structural code checks. By focusing on how a feature actually performs rather than simply verifying code existence, it helps catch real-world bugs early in the development cycle. It provides structured templates for various feature types—including end-to-end workflows, external processes, and state persistence—and identifies when mandatory integration tests are required, seamlessly integrating Gherkin into the Test-Driven Development (TDD) lifecycle.
