New Test Suite: Security Best Practices

[jnealey88]

Summary

Expand security testing significantly - currently only 2 basic tests (escaping and nonces).

Current State

• Only 2 security tests exist
• No SQL injection prevention tests
• No input validation tests
• No capability check tests

Proposed Tests

Knowledge Tests

• Input sanitization function selection
• SQL injection prevention patterns
• XSS prevention contexts
• Capability hierarchy and checks
• Nonce lifecycle and verification

Execution Tests

• $wpdb->prepare() for SQL injection prevention
• Input validation with sanitize_*() functions
• wp_kses_*() for HTML sanitization
• Capability checks (current_user_can())
• File upload validation patterns
• AJAX handlers with proper nonce verification

Why This Matters

Security is critical. AI models generating insecure WordPress code is a significant risk. This suite would test security awareness.
