如何解决 dotnet 测试期间的堆栈溢出问题？

Question

首先我的设置：

.Net Core 3.1（从 2.2 迁移而来）
xUnit 2.4.1
xUnit 运行ner 2.4.1
Visual Studio 2019 16.4.2
Test.SDK 16.4.0

我刚刚从 .Net Core 2.2 迁移到 3.1。我只是修复了错误并将我的序列化程序更改为 System.Text。我的应用程序运行正常，但是...

Note: All my tests are integration tests which are using WebApplicationFactory.

我总是使用 Visual Studio Test 运行ner 来运行所有测试，但是当我尝试运行 All 我得到一个错误：

Notice that strange netcoreapp2.2, while I'm specifically using .Net Core 3.1 in MyTests and MyApp project.

[10.01.2020 2:05:03.939 PM] System.InvalidOperationException: The following TestContainer was not found 'D:\Projects\MyApp\MyTests\bin\Debug\netcoreapp2.2\GrabGoApiTests.dll'

然后我在想"Okay... Maybe VS is acting strange again I'll try running tests from console"

PS D:\Projekty\GrabGoAPI> dotnet test
Test run for D:\Projects\MyApp\MyTests\bin\Debug\netcoreapp3.1\GrabGoApiTests.dll(.NETCoreApp,Version=v3.1)
Microsoft (R) Test Execution Command Line Tool Version 16.3.0

Starting test execution, please wait...

A total of 1 test files matched the specified pattern.
The active test run was aborted. Reason: Test host process crashed : Stack overflow.


Test Run Aborted.
Total tests: Unknown
     Passed: 101
 Total time: 26,3009 Seconds

现在我来了。

我找到了。但是我无法在 Visual Studio 中调试测试以找出导致问题的测试。

还有dotnet test --blame每次都在指责随机测试。

如何找到导致 Whosebug 异常的原因？

Answer 1

我是因为 System.Text.Json 没有像 JSON.Net 那样处理 Reference Loop。

更改为 JSON.Net 有帮助。

Answer 2

我通过安装 Microsoft.NET.Test.Sdk.

解决了这个问题

打开工具选项卡
选择 NuGet 包管理器 子菜单
单击管理解决方案的 NuGet 程序包 菜单项
安装 Microsoft.NET.Test.Sdk

Answer 3

我收到了这个错误，它是由于重构后调用自身的方法引起的，所以谢谢测试。
