.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，当我做docker构建和运行时，我得到以下错误。

它在。net 5 VS +的docker中工作得很好。它在。net 6 VS中工作得很好，但在docker中不能工作。

我做过的事情:

1. 更新框架到。net 6
2. 更新docker以使用。net 6
3. 更新包到6.*

我使用的图片:

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

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

得到的错误如下:

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

Answer 1

由于WebApplicationFactory在。net 6中的"缺乏"，集成测试发生了一些变化。的创业公司。按照这里的新说明:https://learn.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/
