/red-usecase - Write Use-Case Test (Red Phase)

Orchestrates red-agent for usecase layer.

Usage

/red-usecase "Story name" "Scenario name"
/red-usecase 1 "Successful login"
/red-usecase                          # Interactive selection

Workflow

1. •Parse user input (story, scenario)
2. •Load agent instructions from .claude/agents/red-agent.md
3. •Load layer template from .claude/templates/usecase/test-class.md
4. •Execute the following steps:
   • •Read story spec from ProductSpecification/stories/{story}/
   • •Analyze existing tests in backend/usecase/src/test/
   • •Predict expected failure
   • •Write ONE test WITHOUT @Disabled initially
   • •Run test using Skill tool: skill="test-usecase", args="{TestClassName}"
   • •Act when failure doesn't match prediction
   • •Add @Disabled annotation with actual failure reason
   • •Verify test is now SKIPPED
5. •Return result summary

Key Rules

• •ONE test per invocation
• •ALWAYS predict failure BEFORE running
• •Verify RED state before disabling
• •Follow 3-tier architecture (Test -> Statements -> Scope)
• •Use Skill tool for test execution (not gradle directly)
