Test React Apps in Azure Pipelines
Azure Pipelines makes it easy to run tests in the cloud, but I found that a new React projects made with
create-react-app fail to properly test in the cloud using the simple
npm test command. Attempting this would display
No tests found related to files changed since last commit but hang forever.
I solved this problem and got my React app to test properly in the cloud by adding
-- --watchAll=false after
npm test. This is my final
trigger: - master pool: vmImage: "ubuntu-latest" steps: - task: NodeTool@0 inputs: versionSpec: "10.x" displayName: "Install Node.js" - script: npm install displayName: "Install NPM" - script: npm run build displayName: "Build" - script: npm test -- --watchAll=false displayName: "Test"
A working React app that tests properly with Azure Pipelines is GitHub.com/swharden/AliCalc
