Boundary Value Analysis and Equivalence Class Partitioning for Gemini Integration

I'll analyze the key components of your Gemini integration code and provide a structured testing approach using boundary value analysis and equivalence class partitioning.

1. Prompt Input Analysis

Equivalence Classes:

• Valid Prompts: Non-empty strings with meaningful content
• Invalid Prompts: Empty strings, extremely long strings, or strings with special characters

Boundary Values:

• Empty string ("")
• Single character string ("a")
• String at maximum allowed length (if any API limits)
• String just below maximum length

2. Document Content Analysis

Equivalence Classes:

• Empty Document: No content to provide context
• Small Document: Minimal content (few paragraphs)
• Medium Document: Typical usage (multiple paragraphs, some formatting)
• Large Document: Very large content that might affect performance

Boundary Values:

• Empty document
• Document with minimal content (e.g., single paragraph)
• Document at maximum practical size

3. API Response Handling

Equivalence Classes:

• Successful Response: API returns valid content
• Empty Response: API returns empty content
• Error Response: API returns an error
• Timeout: API request times out

Boundary Values:

• Response just at the edge of timeout
• Response with minimum valid content
• Response with maximum allowed content

4. Test Cases

Here's a comprehensive set of test cases based on the analysis:

6. Edge Cases to Consider

1. Race Conditions: Multiple simultaneous requests to the Gemini API
2. Content Sanitization: Handling of HTML/markdown in generated content
3. Error Recovery: How the editor recovers after a failed API call
4. Performance Degradation: How the system behaves under high load
5. Content Limits: Maximum size of content that can be processed

This comprehensive testing approach covers the key boundaries and equivalence classes for your Gemini integration, helping ensure robust functionality across various input conditions and edge cases.
