MuPDF.NET.PDF4LLM.Test

Unit tests for the MuPDF.NET.PDF4LLM project.

Test Structure

The test project follows the same structure as MuPDF.NET.Test and uses NUnit as the testing framework.

Test Classes

• MuPDF4LLM: Tests for the main MuPDF4LLM static class (MuPDF.NET.PDF4LLM namespace)

  • LlamaIndex reader creation
  • Error handling

Running Tests

Tests can be run using:

• Visual Studio Test Explorer
• dotnet test command
• xUnit Test Adapter

Office/HWP integration tests (TestOffice.cs) use the MuPDF.NET.Office / MuPDF.NET.Office.NativeAssets NuGet packages. The test project references MuPDF.NET.PDF4LLM via a project reference (local build), not NuGet.

Test Resources

Test resources (PDF files) should be placed in the resources directory. The columns.pdf file is used as a sample test document.

Notes

• Tests that require OCR are disabled by default (useOcr: false) to avoid dependencies on OCR libraries
• Some tests may require specific PDF files in the resources directory
• Tests follow the Arrange-Act-Assert pattern
