.Net 5 到 .Net 6 的迁移破坏了 docker 中的集成测试，在本地工作正常

Question

在尝试从 .Net 5 迁移到 .Net 6 时，我在 docker build 和运行.

时遇到错误

它在 .Net 5 VS + docker 中工作得很好。它在 .Net 6 VS 中工作得很好，但在 docker.

中不起作用

我做过的事情：

将框架更新为 .Net 6
已更新 docker 以使用 .Net 6
更新包到 6.*

我正在使用的图像：

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS 基础

FROM mcr.microsoft.com/dotnet/sdk:6.0-alpine AS 测试

我得到的错误如下：

 [xUnit.net 00:00:01.87]     XXXApi.IntegrationTests.Tests.AssetTests.GivenNoData_WhenGetAllAssets_ReturnEmptyList [FAIL]
      Failed XXXApi.IntegrationTests.Tests.AssetTests.GivenNoData_WhenGetAllAssets_ReturnEmptyList [1 ms]

Answer 1

由于“缺少”Startup，.NET 6 中的 WebApplicationFactory 的集成测试发生了一些变化。按照此处的新说明进行操作：https://docs.microsoft.com/en-us/aspnet/core/test/integration-tests?view=aspnetcore-6.0#basic-tests-with-the-default-webapplicationfactory

此外，尝试将丢失的项目输出复制到测试层 COPY --from=build /out ./XXXApi/
