首先我的设置：
- .Net Core 3.1（从 2.2 迁移而来）
- xUnit 2.4.1
- xUnit Runner 2.4.1
- 视觉工作室 2019 16.4.2
- 测试.SDK 16.4.0
我刚刚从 .Net Core 2.2 迁移到 3.1。我刚刚修复了错误并将我的序列化程序更改为 System.Text。我的应用程序运行良好，但...
注意：我所有的测试都是使用
WebApplicationFactory.
我一直在使用 Visual Studio Test Runner 来运行所有测试，但是当我尝试 Run All 时出现错误：
请注意，
netcoreapp2.2我在 MyTests 和 MyApp 项目中专门使用 .Net Core 3.1 时很奇怪。

然后我在想“好吧......也许 VS 再次表现得很奇怪我会尝试从控制台运行测试”
PS D:\Projekty\GrabGoAPI> dotnet test
Test run for D:\Projects\MyApp\MyTests\bin\Debug\netcoreapp3.1\GrabGoApiTests.dll(.NETCoreApp,Version=v3.1)

现在我在这里。
我发现了。但我无法在 Visual Studio 中调试测试以找出导致问题的测试。
每次dotnet test --blame都指责随机测试。
如何找到导致 StackOverflow 异常的原因？
