Failed XUnit tests (ASP.NET Core 7 MVC)-CodePudding

I tried to make unit tests for my project, but I ran into the problem of missing testhost.deps.json, although it should have been installed with Microsoft.AspNetCore.Mvc.Testing. As I was told the error may be related to shadow copy, but no matter what I tried to do the error is still displayed just during the creation of the client.

How do I fix this error? Thank you in advance for your answer.

System.InvalidOperationException : Can't find 'C:\Users\flybe\OneDrive\Desktop\HomeworkProject\HomeworkTest\bin\Debug\net7.0\testhost.deps.json'.

using Microsoft.AspNetCore.Mvc.Testing;
using Microsoft.VisualStudio.TestPlatform.TestHost;

namespace HomeworkTest
{
    public class UnitTest1 :IClassFixture<WebApplicationFactory<Program>>
    {
        private readonly WebApplicationFactory<Program> _factory;

        public UnitTest1(WebApplicationFactory<Program> factory)
        {
            _factory = factory;
        }

        [Fact]
        public void Test1()
        {
            var client = _factory.CreateClient();
        }
    }
}

I tried to repeat what was in the training video. I also tried doing a test according to the documentation and the JetBrains article, where this problem was solved with ReSharper, but nothing helped.

CodePudding user response：

Make sure testhost.deps.json file exists in the bin folder. if it's missing make sure you have

<PreserveCompilationContext>true</PreserveCompilationContext>

in your .csproj file.

and if that's not work try to remove the below line from your code.

<GenerateAssemblyInfo>false</GenerateAssemblyInfo>
