Run Net Tests With Preview Native Libs

Run .NET tests with preview native libs

Use this skill when you need to run Whisper.net managed tests and the change does not require rebuilding native runtimes or changing the whisper.cpp submodule.

When to use this

• The task changes managed C# code, tests, docs, samples, or project files only.
• You need native libraries available locally for dotnet test.
• You do not need to validate a new whisper.cpp revision or native build-system change.

Do not use this shortcut for changes under whisper.cpp, native build scripts, runtime package targets, or native binary outputs. In those cases, build the relevant native runtimes instead.

How the preview package is produced

The .github/workflows/upload-build-artifacts.yml workflow:

1. Reads the pinned whisper.cpp short commit SHA.
2. Creates a prerelease tag named preview-nativelibs-<sha>.
3. Uploads one release asset named native-runtimes.zip.
4. Stores the merged native build outputs inside the archive under runtime-artifacts/.

Example release:

https://github.com/sandrohanea/whisper.net/releases/tag/preview-nativelibs-f24588a

PowerShell workflow

Run from the repository root:

$commit = git rev-parse --short=7 HEAD:whisper.cpp
$tag = "preview-nativelibs-$commit"
gh release download $tag --repo sandrohanea/whisper.net --pattern native-runtimes.zip --clobber
Expand-Archive .\native-runtimes.zip -DestinationPath . -Force
Copy-Item .\runtime-artifacts\* .\runtimes\ -Recurse -Force
Remove-Item .\runtime-artifacts -Recurse -Force
Remove-Item .\native-runtimes.zip
dotnet restore .\Whisper.net.slnx
dotnet build .\Whisper.net.slnx --no-restore -warnaserror
dotnet test .\Whisper.net.slnx --no-build --logger "trx"

Bash workflow

Run from the repository root:

commit="$(git rev-parse --short=7 HEAD:whisper.cpp)"
tag="preview-nativelibs-$commit"
gh release download "$tag" --repo sandrohanea/whisper.net --pattern native-runtimes.zip --clobber
unzip -o native-runtimes.zip
cp -R runtime-artifacts/* runtimes/
rm -rf runtime-artifacts native-runtimes.zip
dotnet restore ./Whisper.net.slnx
dotnet build ./Whisper.net.slnx --no-restore -warnaserror
dotnet test ./Whisper.net.slnx --no-build --logger "trx"

Test model handling

The preview native libs release contains native runtime artifacts, not necessarily test model files. Do not set WHISPER_TEST_MODEL_PATH to runtimes/ unless the required ggml-*.bin model files are present there. Without that variable, the tests download models through the normal test fixture path.

Repository hygiene

• Treat downloaded native runtimes as local test inputs, not source changes.
• Do not commit copied binaries from native-runtimes.zip unless the task explicitly asks to update runtime artifacts.
• Remove temporary native-runtimes.zip and runtime-artifacts/ files after unpacking.
