.NET 6.0 + XUnit环境下Allure报告无法生成问题求助

问题背景 #

原本基于.NET Framework 4.7.2 + NUnit的项目可正常生成Allure报告，升级为.NET 6.0 + XUnit项目后，测试执行正常，但执行dotnet test project.proj命令后未生成allure-results文件夹。使用的Allure.XUnit包在其他XUnit项目中可正常工作。

  "allure": {
    "directory": "allure-results",
    "links": [
      "{link}",
      "https://xx.jira.com/browse/{issue}"
    ]
  },
  "specflow": {
    "stepArguments": {

      },

核心排查与解决步骤 #

1. 移除冲突的测试框架依赖 #

项目中同时引用了MSTest和XUnit两套测试框架，会导致测试适配器冲突，Allure.XUnit无法正常拦截XUnit测试执行事件。删除以下MSTest相关引用：

<PackageReference Include="MSTest.TestAdapter" Version="1.3.2" />
<PackageReference Include="MSTest.TestFramework" Version="1.3.2" />

2. 简化Allure配置（非必须但更可靠） #

若项目未使用SpecFlow，可删除配置文件中的specflow节点，避免潜在的配置解析问题：

{
  "allure": {
    "directory": "allure-results",
    "links": [
      "{link}",
      "https://xx.jira.com/browse/{issue}"
    ]
  }
}

3. 重新执行测试命令 #

清理项目后重新构建并执行测试：

dotnet clean
dotnet build
dotnet test project.proj --no-build

4. 验证测试类标记 #

确保测试类使用XUnit的标准特性（如[Fact]、[Theory]），若需更丰富的报告内容，可添加Allure.XUnit的特性（如[AllureSuite]）。

5. 排查详细日志 #

若问题仍存在，添加详细日志参数查看Allure相关报错：

dotnet test project.proj -v detailed
