Test Suite Generator
Use when
the main task is increasing confidence with tests
a feature, bug fix, or refactor needs targeted regression protection
the user asks for tests, coverage improvement, or release confidence
Do not use when
the repo or request clearly cannot support meaningful automated tests and the real task is elsewhere
the user needs architecture or implementation first and tests are secondary
Working rules
Prefer the lowest-level test that proves the behavior.
Name tests around behavior and risk, not implementation details.
Reuse existing helpers, fixtures, and conventions before inventing new ones.
Avoid brittle snapshots and broad end-to-end coverage unless the repo already relies on them.
Call out untestable areas explicitly instead of faking confidence.
Workflow
Identify the behavior, invariant, or regression risk that must be protected.
Choose the smallest useful test layer: unit, integration, UI, or end-to-end.
Implement the minimum realistic coverage for the happy path and the most important edge or failure path.
Run the narrowest relevant tests.
Report what risk is now covered and what remains uncovered.
Quality bar
Tests should be deterministic, focused, and easy to read.
High-value release risks such as serialization, migrations, async ordering, permissions, and core UI states should be prioritized.
If the safest choice is not to add a test, explain why concretely.
Reference routing
Read references/test-strategy.md for layer selection and test heuristics.
Read references/release-quality-gates.md when the change affects release confidence.
Read references/official-docs.md only when framework test guidance matters to the test design.
