Testing Infrastructure

Testing frameworks for analyzers, code fixes, and source generators

ANcpLua.Roslyn.Utilities.Testing provides two testing paradigms:

1. Roslyn Testing - In-memory compilation testing for analyzers, code fixes, and generators
2. MSBuild Testing - Integration testing with real dotnet build commands

Installation

<PackageReference Include="ANcpLua.Roslyn.Utilities.Testing" Version="1.8.0" />

Roslyn Testing

For unit testing analyzers, code fixes, and source generators without invoking MSBuild.

using ANcpLua.Roslyn.Utilities.Testing;

[Fact]
public async Task Analyzer_ReportsWarning()
{
    var test = new AnalyzerTest<MyAnalyzer>()
        .WithSource("""
            class Sample
            {
                void Method() { [|BadApi()|]; }
            }
            """);

    await test.RunAsync();
}

MSBuild Testing

For integration testing with real builds - testing SDK features, package behavior, or build-time behavior.

See MSBuild Testing for details.
