Development · overview

Test

Write tests for existing code or validate test coverage.

/development-test <feature>

Purpose

The Test skill analyzes existing code, identifies untested paths, writes tests for edge cases and critical functionality, and reports coverage gaps.

Usage

Example:

/development-test auth-system

What It Does

  1. Reads source code and identifies all public interfaces
  2. Assesses current test coverage
  3. Writes tests for untested paths — critical paths first, then edge cases
  4. Runs the full test suite
  5. Reports coverage gaps and test health

Output

Creates .singularskills/development/<feature>/03-test.md containing:

  • Coverage assessment (what was and wasn't tested)
  • Tests added with descriptions
  • Remaining gaps
  • Test health notes (flaky or slow tests)

Build

Execute a plan task-by-task with TDD discipline and progress tracking.
