when using xunit test(SUT),there is an exception throwed!

[codelovercc]

Here is the code in my xunit test project

App = new WebApplicationFactory<TProgram>().WithWebHostBuilder(builder => {});
Client = App.CreateClient();

when I run a unit test,the web application throw exception of DirectoryNotFoundException.the console output is under below.
I noticed that JsonStringLocalizerFactory.Create Method called PathHelpers.GetApplicationRoot(),the PathHelpers.GetApplicationRoot() Method simply call Assembly.GetExecutingAssembly().Location. that's the problem. Assembly.GetExecutingAssembly().Location Gets the current executing assembly which is my test project assembly. it returned a path of my test project build directory. normally, I want JsonStringLocalizer to locate the resources file in the Resource directory under my web project, but a unit test can't do that.the Microsoft's StringLocalization is working well in my unit test project.I also noticed that they are using WebApplicationFactoryContentRootAttribute to resolve the localization resources directory. check this document How the test infrastructure infers the app content root path
.Please solve this issue.If something I've missed or went wrong,Please tell me.Thank you.

Thanks for reporting, I will try to run the tests again and check if there's an exception

Thanks for replying, When I run my WebApplication in my Unit Test project. JsonStringLocalizerFactory create a JsonStringLocalizer with wrong Resources Path, the path should be in my WebApplication project,turns out the JsonStringLocalizer used my Unit Test project's path. But my Unit Test project doesn't have a directory named Resource, and I want my WebApplication project in unit test still using my Resources path under my WebApplication project, just like I'm using Microsoft's StringLocalization.I don't want to copy my Resources files from my WebApplication project to my Unit Test project.
Is that clear enough? Sorry, English is not my forte.
In my WebApplication project's Main method:

        builder.Services.AddJsonLocalization(options => options.ResourcesPath = "Resources");

In my XUnit test project to create a Test for WebApplication project

        App = new WebApplicationFactory<Program>().WithWebHostBuilder(builder => {});
        Client = App.CreateClient();//Client is an instance of HttpClient

and then I used

Client.Get("route/to/controller/action")

After this, the WebApplication project throws an exception System.IO.DirectoryNotFoundException.

Please create a PR showing your unit test which thrown the exception, then I can try to figure out why it's happening

[codelovercc]

Sorry,I don't get it. What is PR? Pull Request? Demo? Or something others?I gonna Google it.Wait me back.Thks.

Hi, hishamco. IWebHostEnvironment.Environment.ContentRootPath this is what i want.
Is there a way to use IWebHostEnvironment.Environment.ContentRootPath in class PathHelpers.GetApplicationRoot()

using System.IO;
using System.Reflection;

namespace My.Extensions.Localization.Json.Internal
{
  public static class PathHelpers
  {
    public static string GetApplicationRoot() => Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
  }
}

Never mind!
After all this, I've made a mistake. I have a typo about my Resource directory name. I typed Recourse as my Resource directory name. so this exception was thrown.Sorry to bother you.
Now I just correct the resource directory name and modify my code in the Program.cs

builder.Services.AddJsonLocalization(options =>
        {
            options.ResourcesPath =
                Path.Combine(GlobalServiceProvider.App!.Environment.ContentRootPath, "Resources");
//GlobalServiceProvider.App.Environment is type of IWebHostEnvironment
        });

Thanks for reply.Thank you very much. By the way,PR => Pull request. got it!.
Please close this issue.

No problem at all, the important thing is everything works as expected ;)
