NUnit.Engine.NUnitEngineUnloadException:遇到多个异常。有关详细信息，请检索AggregatedExceptions属性

在build server TeamCity上运行测试时，我的日志中出现[subject]，步骤失败

这段代码是包含大量代码的结果，这使得很难精确地指出我做错了什么（我不希望回滚更改并在小步骤中再次执行）

我怎样才能解决这个问题？我怎样才能确定问题出在哪里

我在跑步 -nunit nuget 3.10.1（撰写本文时的最新官方） -使用x64/v4.0构建服务器上的nunit.console 3.8.0

在我的开发机器上本地运行（通过R#），我看不到任何问题

这些测试是基于数据库的测试，我为测试（案例）创建了一个新的数据库，然后在测试完成后将其删除

欢迎任何建议

如果它对任何人都有帮助的话——最终我让它发挥了作用

也可能是数据库集成测试，但我最终通过的更改如下所示

StructureMap的IContainer是IDisposable的，显然单元测试过程在完成测试后保留在二进制文件上，从而防止卸载

以前

[测试]
可创建控制器的公共无效项YiocContainer（）
{
//安排
var sut=WebIoC.Initialize（）；
//表演
var searchRequestController=sut.GetInstance（）；
var searchStatusController=sut.GetInstance（）；
//断言
Assert.IsNotNull（searchRequestController）；
Assert.IsNotNull（searchStatusController）；
}

之后

[测试]
可创建控制器的公共无效项YiocContainer（）
{
//安排
使用（var sut=WebIoC.Initialize（））
{
//表演
var searchRequestController=sut.GetInstance（）；
var searchStatusController=sut.GetInstance（）；
//断言
Assert.IsNotNull（searchRequestController）；
Assert.IsNotNull（searchStatusController）；
}
}

其中WebIOC.Initialize（）看起来像（标准的东西）：

公共静态类WebIoC
{
公共静态IContainer初始化（）
{
返回新容器（c=>
{
c、 AddRegistry（）；
c、 AddRegistry（）；
c、 扫描（扫描=>
{
扫描。卡入总成（）；
scan.WithDefaultConventions（）；
});
});
}
}
