Creating Feature Tests

Create behavior-driven, fail-first feature tests for user-facing behaviors.

What you should do

1. Collect behavior scenario from user – Extract the core user-facing behavior to validate. If unspecified, analyze the codebase for primary user flows (e.g., authentication, form submission, navigation) and select a behavior that lacks clear test coverage.

2. Analyze feature dependencies and requirements – Examine the target feature's implementation to identify:

   • External services, APIs, or databases required for the feature
   • Authentication or authorization dependencies
   • UI components, forms, or user interaction elements
   • Configuration, environment variables, or feature flags
   • Third-party integrations or external systems

3. Check for existing test coverage – Search the tests/features/ directory or equivalent for files or test cases related to the behavior. If the behavior is already tested, skip to Step 10 to optionally refactor, expand, or annotate the test.
