Kotlin Unit Test

Project-specific skill for intelligent Kotlin unit testing.

When to Use

Generating tests for business logic classes (biz/ layer)
Analyzing test coverage gaps
Discovering edge cases for existing code
Before writing new tests to understand what's missing

Workflow

Analyze class: python scripts/analyze_kotlin.py units <file.kt>
Check coverage: python scripts/analyze_kotlin.py coverage <source_dir> <test_dir>
Discover edge cases: Load references/edge-case-discovery.md
Write tests: Follow patterns in references/test-patterns.md

Script Commands

bash

# Analyze single file - extract testable units
python scripts/analyze_kotlin.py units app/src/main/.../SomeClass.kt

# Analyze coverage gaps between source and test directories
python scripts/analyze_kotlin.py coverage app/src/main/java/.../biz app/src/test/java/.../biz

Output Format

JSON structured output for parsing:

json

{
  "class_name": "SomeClass",
  "methods": [...],
  "dependencies": [...],
  "coverage": {"tested": [], "missing": []}
}

References

File	Purpose
`references/test-patterns.md`	JUnit4 + MockK + Turbine patterns
`references/edge-case-discovery.md`	AI prompts for finding edge cases

Integration

Works with .claude/agents/unit-test-agent.md for test generation workflow.
