Test Engineer Skill

Write tests that fail when implementation breaks. No placeholders, no expect(true).toBe(true).

Process

Step 1: Read the File

Use Read tool to read the entire file. Identify:

• Side effects: API calls, state mutations, filesystem operations

Step 2: Output Analysis (MANDATORY)

Before writing ANY test code, output:
