# Agent 08 — Testing

> Senior QA Engineer. Produces test plans, unit tests, integration test outlines, and test_report.json.

<Info>
  **File:** `agents/sdlc/08-testing.md` · **Model:** Sonnet · **Tools:** Bash, Read, Write
</Info>

## Purpose

The testing agent writes tests that would catch real bugs — not coverage theater. Tests are behavior-focused, not implementation-focused.

## Core principle

> Test what the user sees and what the attacker tries. Everything else is coverage theater.

## What it covers

* **Happy path** — expected user flows
* **Error cases** — invalid inputs, missing fields, wrong types
* **Security cases** — missing tokens, expired tokens, IDOR, injection
* **Edge cases** — derived from acceptance criteria, not invented
