在天蓝色管道中分离构建和测试阶段的正确机制是什么？

Question

我有一个带有以下 azure-pipelines.yml 的玩具 C++ cmake 项目（请参阅 HelloAzure 了解来源）。

# Starter pipeline
# Start with a minimal pipeline that you can customize to build and deploy your code.
# Add steps that build, run tests, deploy, and more:
# https://aka.ms/yaml

trigger:
    - master 
variables:
  SOURCE_DIR: '$(System.DefaultWorkingDirectory)'
  BUILD_DIR: '$(SOURCE_DIR)/build'
  INSTALL_DIR: '$(SOURCE_DIR)/install'

stages:
  - stage: Build 
    displayName: Build 
    pool: 
      vmImage: ubuntu-latest    
    jobs:
      - job: BuildLinux 
        strategy:
          matrix:
            Release:
              BUILD_TYPE: 'Release'
            Debug:
              BUILD_TYPE: 'Debug'
        steps:
          - script: | 
              echo "mkdir BUILD_DIR $(BUILD_DIR)"
              mkdir $(BUILD_DIR)
              echo "cd build directory "
              cd $(BUILD_DIR)
              echo " Run configure command"
              cmake -DCMAKE_INSTALL_PREFIX=$(INSTALL_DIR)/$(BUILD_TYPE) $(SOURCE_DIR)
              echo "running cmake build command"
              cmake --build . --target install --config $(BUILD_TYPE) -j 12 
  - stage: BuildTests
    dependsOn: Build
    displayName: BuildTests 
    jobs: 
      - job: RunCTestLinux 
        steps: 
          - script: |
              cd $(BUILD_DIR)
              ctest

在本地我可以执行以下操作：

# download sources
git clone https://github.com/CiaranWelsh/HelloAzure.git

# build
cd HelloAzure
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=../install ..
cmake --build . --target install --config Release -j 12

# test
ctest

我正在尝试在 Azure 中重现此工作流程。只使用一个阶段是微不足道的，但是一旦我尝试运行在“测试”阶段进行测试，Azure simply re-downloads the sources and tried to run the tests without first having ran the build command.

所以我的问题是，在 azure-pipelines 中分离项目的构建和测试阶段的正确机制是什么？

Answer 1

针对您的场景，您可以尝试以下方法：

1 .在Build阶段，添加一个发布构建输出的任务。例如：

steps:
- publish: string # path to a file or folder
  artifact: string # artifact name
  displayName: string  # friendly name to display in the UI

2 .在BuildTests阶段，添加下载构建输出的任务：

steps:
- download: [ current | pipeline resource identifier | none ] # disable automatic download if "none"
  artifact: string ## artifact name, optional; downloads all the available artifacts if not specified
  patterns: string # patterns representing files to include; optional
  displayName: string  # friendly name to display in the UI

3 .非部署作业自动签出源代码。使用 checkout 关键字来配置或抑制此行为。在 BuildTests 阶段，添加以下步骤以自动抑制检出的源代码：

steps:
- checkout: none
