New Test Suite: Theme Development

[jnealey88]

Summary

Add tests for WordPress theme development APIs - currently no theme-specific tests exist.

Current State

• Zero theme API tests
• No template hierarchy tests
• No theme customizer tests
• No theme hooks coverage

Proposed Tests

Knowledge Tests

• Template hierarchy order
• Theme support features
• Child theme mechanics
• Customizer API concepts

Execution Tests

• add_theme_support() for various features
• Theme hooks (wp_head, wp_footer, wp_body_open)
• Template hierarchy and get_template_part()
• Customizer settings with get_theme_mod()
• Enqueuing theme assets properly
• get_template_directory() vs get_stylesheet_directory()

Why This Matters

Theme development is a core WordPress skill. Models should understand theme architecture and best practices.
