Add comprehensive tests for includeModels and excludeModels configuration options

[Copilot]

The includeModels and excludeModels configuration options were already implemented in the codebase but lacked comprehensive test coverage to verify their functionality. This PR adds a complete test suite to ensure these model filtering features work correctly.

What was added

Comprehensive Test Suite (tests/model-filtering.test.ts)

includeModels Configuration Tests:

• Include only specified models (includeModels: "User,Post")
• Include single model (includeModels: "User")
• Handle whitespace in model names (includeModels: " User , Post ")
• Handle non-existent models gracefully
• Include all models when empty string or undefined

excludeModels Configuration Tests:

• Exclude specified models (excludeModels: "Profile")
• Exclude multiple models (excludeModels: "Profile,Post")
• Handle whitespace in model names
• Handle non-existent models gracefully
• Include all models when empty string

Combined Configuration Tests:

• Apply includeModels first, then excludeModels
• Handle complex filtering scenarios

Example Usage

The includeModels option can be used in schema.prisma to generate OpenAPI specs for only specific models:

generator openapi {
  provider = "prisma-openapi"
  output   = "./openapi"
  includeModels = "User,Post"  // Only generate OpenAPI for these models
}

Test Results

All 27 tests pass (14 existing + 13 new model filtering tests), confirming that:

• The implementation correctly filters models based on configuration
• Enum references are properly handled in filtered models
• Edge cases like non-existent models and whitespace are handled gracefully
• Combined includeModels and excludeModels work as expected

Fixes #24.

Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• binaries.prisma.sh
  • Triggering command: node /home/REDACTED/work/prisma-openapi/prisma-openapi/node_modules/.bin/../prisma/build/index.js generate (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
