What this image is about?

This image is designed to run Service Fabric oriented unit-tests (.NET Core) on Linux.

The latest version can be found on DockerHub.

Why is that needed?

Consider the following simple test:

public class MyStatefulService : Microsoft.ServiceFabric.Services.Runtime.StatefulService
{
    public MyStatefulService(
        StatefulServiceContext serviceContext)
        : base(serviceContext)
    {
    }

    protected override Task RunAsync(
        CancellationToken cancellationToken)
    {
        if (cancellationToken.IsCancellationRequested)
        {
            throw new InvalidOperationException();
        }
        return Task.CompletedTask;
    }
}

public class MyStatefulServiceTests
{
    [Fact]
    public async Task RunAsync_Should_raise_InvalidOperationException_When_CancellationToken_is_cancelled()
    {
        // Arrange
        var instance = new MyStatefulService(MockStatefulServiceContextFactory.Default);
        var cancellationTokenSource = new CancellationTokenSource();
        
        // Act, Assert
        cancellationTokenSource.Cancel();

        await Assert.ThrowsAsync<InvalidOperationException>(() => instance.InvokeRunAsync(cancellationTokenSource.Token));
    }
}

Despite it's simplicity this unit-test requires installed servicefabric runtime and servicefabricsdkcommon package installed to run. These packages cannot be installed as part of container build see issue.

The image solves the exactly this problem by performing manual copy of the required files from the packages.
