Overview

Comprehensive integration tests specifically for v2.3.0 features:

  • Form body support (application/x-www-form-urlencoded)
  • File upload support (multipart/form-data)
  • Arbitrary path lengths

These tests verify the complete HTTP workflow including content type handling, request parsing, and response generation.

  • Form fields: action, userId
  • Files: new-avatar.jpg (image/jpeg), updated-resume.pdf (application/pdf)

Test Methodology

Integration Testing Approach

  • Uses WebApplicationFactory<Program> for full HTTP testing
  • Replaces real LLM client with FakeLlmClient for predictable results
  • Tests actual HTTP request/response cycle

Validation Strategy

Tests validate:

  1. HTTP Status Code: All requests return 200 OK
  2. Content Type: Responses are application/json
  3. Valid JSON: Response is parseable JSON
  4. Response Structure: Contains expected fields (id, name, etc.)

Test Data Coverage

  • Special Characters: Quotes, backslashes, newlines, tabs, carriage returns
  • Unicode: UTF-8, emoji, CJK characters
  • File Sizes: Empty (0 bytes) to large (5MB)
  • Path Depths: 2 segments to 21 segments
  • Query Complexity: Simple to 10+ parameters

Key Features Validated

✅ Form Body Support

  • Single and multiple field values
  • Array conversion for duplicate field names
  • Special character escaping
  • Unicode and emoji support
  • Empty value handling

✅ File Upload Support

  • Single and multiple file uploads
  • Memory-safe streaming (5MB+ files)
  • Mixed form fields and files
  • Various content types (text, PDF, JPEG, binary)
  • Empty file handling
  • Special characters in filenames

✅ Arbitrary Path Lengths

  • Up to 21 segments tested
  • RESTful resource structures
  • Complex query strings
  • POST requests to deep paths
  • File uploads to deep paths

✅ Combined Scenarios

  • Deep paths + form data
  • Deep paths + file uploads
  • Special characters + multiple features
