Why the TestServer (AspNetCore) gives 404 error on static files?

Question

I have a sample server

var host = new WebHostBuilder()
                .UseKestrel()
                .UseContentRoot(Directory.GetCurrentDirectory())
               


        

Answer 1

Another approach is to copy those files into your unit test project

Then

As far as you maintain the same structure folder of the project that you are testing, it will find out the files and pass it to the dependency injection process.

Answer 2

XUnit starts the site from a different directory. We've had to work around it like this: https://github.com/aspnet/StaticFiles/blob/d692066b2bd711653150ad2cccc2268583355532/test/Microsoft.AspNetCore.StaticFiles.Tests/StaticFilesTestServer.cs#L20
