When I'm setting up integration tests in AspNetCore, the content root is all messed up because Directory.GetCurrentDirectory() resolves to something like ./test/MySolution.Web.Tests/bin/Debug/netcoreapp2.1/, and the most reliable way to get it back to the expected ./src/MySolution.Web/ is to traverse directories up until you find a .sln file, and then find some known path relative to the folder in which the .sln file lives.

The code is simple, but I got tired of the copy pasta whenever I set up an integration test project. Bingo bango, the SolutionResolution was born.

Installation

Add the NuGet package

PM> Install-Package jaytwo.SolutionResolution

Normal Usage

AspNetCore 2.1 Integration Tests

public class WebApplicationFactory
    : WebApplicationFactory<Startup>
{
    protected override void ConfigureWebHost(IWebHostBuilder builder)
    {
        builder.UseEnvironment("Development");

        var contentRoot = SlnFileResolver.Default.ResolvePathRelativeToSln("examples/AspNetCore2_1");
        builder.UseContentRoot(contentRoot);
    }
}

AspNetCore 1.1 Integration Tests

public class TestServerFixture
{
    private readonly TestServer _server;
    
    public HttpClient CreateClient() => _server.CreateClient();

    public TestServerFixture()
    {
        var contentRoot = SlnFileResolver.Default.ResolvePathRelativeToSln("examples/AspNetCore1_1");

        _server = new TestServer(new WebHostBuilder()
            .UseEnvironment("Development")
            .UseContentRoot(contentRoot)
            .UseStartup<Startup>());
    }

    public void Dispose()
    {
        _server?.Dispose();
    }
}
