GitHub Actions中dotnet test未执行测试的问题求助

问题场景 #

我正在创建GitHub Actions工作流构建并测试.NET项目，工作流文件如下：

name: build and test

on:
  push:
  pull_request:
    branches: [ main ]
    paths:
    - '**.cs'
    - '**.csproj'

env:
  DOTNET_VERSION: '7.0' # The .NET SDK version to use

jobs:
  build-and-test:
    
    name: build-and-test-${{matrix.os}}
    runs-on: ${{ matrix.os }}
    strategy:
      matrix:
        os: [ubuntu-latest]

    steps:
    - uses: actions/checkout@v3
    - name: Setup .NET Core
      uses: actions/setup-dotnet@v3
      with:
        dotnet-version: ${{ env.DOTNET_VERSION }}
      
    - name: Install dependencies
      run: dotnet restore Starmap/Starmap.sln
      
    - name: Build
      run: dotnet build Starmap/Starmap.sln --configuration Release --no-restore
      
    - uses: actions/checkout@v3
    - uses: isbang/compose-action@v1.4.1
      with:
        compose-file: "infra.yaml"
    
    - name: Test
      run: dotnet test Starmap/Starmap.sln --no-restore --verbosity normal

所有步骤显示成功，但测试并未实际运行（我特意修改测试用例使其失败，却未触发工作流失败），且dotnet test步骤输出仅包含构建成功信息，无测试执行记录：

Run dotnet test Starmap/Starmap.sln --no-restore --verbosity normal
  dotnet test Starmap/Starmap.sln --no-restore --verbosity normal
  shell: /usr/bin/bash -e {0}
  env:
    DOTNET_VERSION: 7.0
    DOTNET_ROOT: /usr/share/dotnet
  
Build started 02/18/2023 11:41:46.

Build succeeded.

问题原因 #

1. 重复执行actions/checkout@v3：第一次checkout已经拉取代码并完成依赖安装、构建，第二次checkout会将工作目录重置为仓库原始状态，覆盖了特意修改的测试用例，同时丢失之前的构建产物。
2. 测试与构建配置不一致：dotnet build使用Release配置，但dotnet test默认用Debug配置，加上--no-restore参数后，测试步骤会重新构建Debug版本，却未正确触发测试执行。
3. 基础设施服务未就绪：使用compose-action启动服务后直接执行测试，可能因依赖服务未启动导致测试静默跳过。

修复方案 #

1. 移除重复的checkout步骤 #

删除第二次的- uses: actions/checkout@v3，保留第一次即可，避免代码和构建产物被重置。

2. 统一测试与构建配置 #

在dotnet test命令中添加--configuration Release参数，与构建阶段保持一致，避免重复构建：

dotnet test Starmap/Starmap.sln --configuration Release --no-restore --verbosity normal

3. 等待基础设施服务就绪 #

在测试前添加步骤，等待服务启动完成（示例以数据库端口5432为例，需根据实际服务调整）：

- name: Wait for services to be ready
  run: |
    until nc -z localhost 5432; do
      sleep 1
    done

修复后的完整工作流 #

name: build and test

on:
  push:
  pull_request:
    branches: [ main ]
    paths:
    - '**.cs'
    - '**.csproj'

env:
  DOTNET_VERSION: '7.0' # The .NET SDK version to use

jobs:
  build-and-test:
    
    name: build-and-test-${{matrix.os}}
    runs-on: ${{ matrix.os }}
    strategy:
      matrix:
        os: [ubuntu-latest]

    steps:
    - uses: actions/checkout@v3
    - name: Setup .NET Core
      uses: actions/setup-dotnet@v3
      with:
        dotnet-version: ${{ env.DOTNET_VERSION }}
      
    - name: Install dependencies
      run: dotnet restore Starmap/Starmap.sln
      
    - name: Build
      run: dotnet build Starmap/Starmap.sln --configuration Release --no-restore
      
    - uses: isbang/compose-action@v1.4.1
      with:
        compose-file: "infra.yaml"
    
    - name: Wait for services to be ready
      run: |
        # 根据你的基础设施服务调整端口和等待逻辑
        until nc -z localhost 5432; do
          sleep 1
        done
    
    - name: Test
      run: dotnet test Starmap/Starmap.sln --configuration Release --no-restore --verbosity normal

额外检查点 #

• 确认解决方案文件Starmap.sln已正确包含所有测试项目，且测试项目的TargetFramework与.NET版本匹配。
• 若测试需要特定环境变量，可在env字段或测试步骤中添加。
