[themattwilliams]

What/Why/How?

What

• Added a new API Testing learning center card with streamlined index page
• Created /learn/testing section with hub-style navigation to existing resources
• Updated content structure to point to relevant Arazzo and contract testing articles

Why

• Fill content gap: API testing is a core competency but lacked a dedicated learning hub
• Support product adoption: Helps users discover and navigate to Redocly's testing-related content
• Improved discoverability: Creates a central entry point for API testing resources
• Better user experience: Simplified navigation with FAQ-style structure

How

• Hub-and-spoke approach: Created index page that points to existing high-quality content
• Content consolidation: Removed placeholder articles, kept proven educational content
• Integration: Updated learning center cards.ts to surface testing content prominently
• User-friendly design: FAQ format with annotated links and multiple CTAs

Reference

Files Created/Modified:

• pages/learning-center/cards.ts - Added API Testing card (id: 5)
• learn/testing/index.md - Hub page with FAQ-style navigation
• learn/testing/sidebars.yaml - Updated sidebar structure
• Removed placeholder articles (best-practices.md, getting-started.md, etc.)

Content Structure:

• Index page with FAQ-style navigation
• Links to Contract Testing 101 (comprehensive foundational guide)
• Links to Testing API Workflows with Respect (hands-on Arazzo/Respect tutorial)

Testing

Manual Testing Performed:

• ✅ Local preview: Verified content renders correctly
• ✅ Navigation: Confirmed links work to both internal and cross-section articles
• ✅ Card integration: API Testing card appears in learning center with correct navigation
• ✅ Content flow: Verified logical progression and clear CTAs

Additional Notes:
Please note, the current implementation focuses on creating a navigation hub that points to existing high-quality resources. The Contract Testing 101 article provides comprehensive foundational content, while the Arazzo testing article offers hands-on workflow testing guidance. This approach leverages existing proven content while creating better discoverability. Future targeted articles can be added to expand the section as needed.
