Test Generation Skill

Description: Generates deterministic unit and edge case tests for a given target code file.

Execution Contract

• Guarantees: Outputs structured, compilable test code verifying happy paths, edge cases, and failure modes using mock isolated dependencies.
• Does NOT Guarantee: 100% test coverage or that tests will logically succeed without human verification of the mocked states.

I/O Paths (Standardized)

• Input Artifact: artifacts/input/test-generation/target_code.txt
• Output Artifact: artifacts/output/test-generation/report.json

Instructions

1. Analyze the input code structure and identify required test bounds.
2. Generate minimum 5 tests spanning happy_path, edge_case, and failure_mode.
3. Provide the full code block for each test.
4. If testing relies on mocked dependencies, explicitly list them.
5. Output MUST match the exact schema detailed in schema.json.

Hard Rejection Criteria (Validation Triggers)

Your output will be REJECTED via the deterministic validator if:

• You output fewer than 5 tests.
• You fail to include edge case coverage.
• The tests are pseudocode or do not contain valid assertions.

If you cannot fulfill these constraints, fallback to the failure output:

{
  "status": "failed",
  "reason": "<reason>",
  "retryable": true
}
