GitHub操作的输出为空

Question

我正在创建我的第一个GitHub操作，但我无法弄清楚为什么输出为空。

action.yml

name: "Run Endtest functional tests"
description: "Register a deployment event with Endtest and run the functional tests"
branding:
  icon: play-circle
  color: white
inputs:
  app_id:

    required: true
  number_of_loops:

    required: true

outputs:

runs:
  using: "composite"
  steps:
    - run: sudo apt-get install jq
      shell: bash 
    - run: sudo chmod +x ${{ github.action_path }}/test.sh
      shell: bash 
    - run: echo "${{ inputs.api_request }}"

    - run: ${{ github.action_path }}/test.sh ${{ inputs.app_id }} ${{ inputs.app_code }} "${{ inputs.api_request }}" ${{ inputs.number_of_loops }}

  if [ "$result" == "Test is still running." ]
  then
    status=$result
    # Don't print anything
  elif [ "$result" == "Processing video recording." ]
  then
    status=$result
    # Don't print anything
  elif [ "$result" == "Stopping." ]
  then
    status=$result
  elif [ "$result" == "Erred." ]
  then
    status=$result
    echo $status
  elif [ "$result" == "" ]
  then
    status=$result
    # Don't print anything
  else
     testsuitename=$( echo "$result" | jq '.test_suite_name' )

     endtime=$( echo "$result" | jq '.end_time' )   
     
     echo $testsuitename
     echo $configuration
     echo $testcases
     echo $passed
     echo $failed
     echo $errors
     echo $starttime
     echo $endtime
     
     echo "::set-output name=test_suite_name::$testsuitename"
     echo "::set-output name=configuration::$configuration"
     echo "::set-output name=test_cases::$testcases"
     echo "::set-output name=passed::$passed"
     echo "::set-output name=failed::$failed"
     echo "::set-output name=errors::$errors"
     echo "::set-output name=start_time::$starttime"
     echo "::set-output name=end_time::$endtime"
     #echo "::set-output name=detailed_logs::$detailedlogs"
     #echo "::set-output name=screenshots_and_video::$screenshotsandvideo"
     exit 0
  fi
done
exit

我已经在 GitHub Marketplace 上发布了这个操作，现在我正在试图从另一个仓库中使用/测试它，方法如下：

main.yml

name: CI

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Run a one-line script
        run: echo Hello, world!
        
      - name: Run Endtest functional tests
        id: endtest_functional_tests
        uses: endtest-technologies/github-run-tests-action@v1.3.0.0.3
        with:
          app_id: "85205402"
          app_code: "79973826"
          api_request: "https://endtest.io/api.php?action=runTestSuite&appId=85205402&appCode=79973826&testSuite=106877&selectedPlatform=windows&selectedOs=a&selectedBrowser=chrome&selectedResolution=d&selectedLocation=sanfrancisco&selectedCases=491130&writtenAdditionalNotes="
          number_of_loops: 6
          
      - name: Get the test suite name output
        run: echo "${{ steps.endtest_functional_tests.outputs.test_suite_name }}"
        
      - name: Get the configuration output
        run: echo "${{ steps.endtest_functional_tests.outputs.configuration }}"

      
      - name: Get multiple outputs
        run: |
          echo "${{ steps.endtest_functional_tests.outputs.test_suite_name }}"
          echo "${{ steps.endtest_functional_tests.outputs.configuration }}"

从构建日志中看，我可以看到我的操作成功调用，API请求开始，我可以看到输出，直到::set-output的部分被打印出来。

而我GitHub操作生成的输出是空的。

我真的很感激在这件事上得到一些帮助，因为我已经试图让它工作了两天了。

从我所读的内容来看，应该可以像这个人在这篇文章中所做的那样，从一个.sh文件中使用::set-output。

那个庞大的 if ... elif ... else 在长大后想成为一个 case 语句。反复调用 jq 处理小字符串的方式看起来也需要重构，但我无法迅速确定具体的方法。 - tripleee

@tripleee 说得对。那段代码需要进行重构。你有关于为什么 ::set-output 在我的情况下似乎不起作用的任何想法吗？ - John Winchester

您只是在设置操作的最后一步的输出，但没有设置操作的输出。

您需要使用步骤的输出（根据https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions#outputs-for-composite-actions中所述）设置操作输出的value。

name: "Run Endtest functional tests"
description: "Register a deployment event with Endtest and run the functional tests"

inputs:
  [...]
outputs:
  test_suite_name:
    description: "The name of the test suite"
    value: ${{ steps.run-script.outputs.test_suite_name }}
  [...]

runs:
  using: "composite"
  steps:
    - run: sudo apt-get install jq
      shell: bash 
    - run: sudo chmod +x ${{ github.action_path }}/test.sh
      shell: bash 
    - run: echo "${{ inputs.api_request }}"
      shell: bash 
    - run: ${{ github.action_path }}/test.sh ${{ inputs.app_id }} ${{ inputs.app_code }} "${{ inputs.api_request }}" ${{ inputs.number_of_loops }}
