在我完成我的 e2e 测试并测试它们是否有效之后。我想更改 Azure Devops CI 以运行 e2e 测试。所以我将这些设置添加到 YAML 文件中：
pool:
vmImage: 'ubuntu-latest'
steps:
- task: DeleteFiles@1
displayName: 'Delete JUnit files'
inputs:
SourceFolder: /junit
Contents: 'TESTS*.xml'
- task: NodeTool@0
inputs:
versionSpec: '10.x'
displayName: 'Install Node.js'
- script:
npm install -g @angular/cli
npm install
ng build --prod
displayName: 'npm install and build'
- task: Npm@1
displayName: 'npm install node_modules'
- task: Npm@1
displayName: 'Build Angular'
inputs:
command: custom
customCommand: run build
- task: Npm@1
displayName: 'Test Angular'
inputs:
command: custom
customCommand: run test -- --watch=false --code-coverage
- task: Npm@1
displayName: 'Test e2e Angular'
inputs:
command: custom
customCommand: run e2e
- task: PublishCodeCoverageResults@1
displayName: 'Publish code coverage Angular results'
condition: succeededOrFailed()
inputs:
codeCoverageTool: Cobertura
summaryFileLocation: 'coverage/front-end/cobertura-coverage.xml'
reportDirectory: coverage/front-end
failIfCoverageEmpty: true
- task: PublishTestResults@2
displayName: 'Publish Angular test results'
condition: succeededOrFailed()
inputs:
searchFolder: $(System.DefaultWorkingDirectory)/junit
testRunTitle: Angular
testResultsFormat: JUnit
testResultsFiles: "**/TESTS*.xml"
运行此构建时，我收到下一个错误：

它表明它只支持 ChromeDriver 78，但在上面的日志中，它说它安装了 ChromeDriver 78。也许还有另一个 ChromeDriver 实例，但我找不到它。我还尝试在没有安装任何 Chrome 的情况下在本地运行测试，并且效果很好。
最后一段代码是量角器配置文件。也许它有什么问题。
