This is probably not a problem with npm. There is likely additional logging output above. Test-run the npm module in-the-making while it is being developed using two techniques both, local test run* and parallel test run**. npm … code ELIFECYCLE npm ERR!

I've been using create-react-app in conjunction with lerna repos and for the most part its been an awesome experience.

syscall spawn npm ERR! If necessary, classnames and function names can be enabled for profiling purposes. file sh npm ERR! Since create-react-app defaults to entering watch mode on test… The one issue I've been seeing is when trying to issue lerna run test commands to test all packages that have a "test" script.

Failed at the roffice@0.1.0 build script. When I first started learning to test my apps back in the day, I would get very frustrated with the different types, styles and technologies used for testing, along with the disbanded array of blog posts, tutorials and articles.

errno 1 npm ERR! It correctly bundles React in production mode and optimizes the build for the best performance. Register and publishing the npm module to nmp js. I am trying to add a unit test using Jest and Enzyme. errno ENOENT npm ERR! code ELIFECYCLE npm ERR!

roffice@0.1.0 build: `react-scripts build` npm ERR! npm ERR! npm ERR! Darwin 16.0.0 npm ERR! 3. The most inefficient way to go about this is to publish your package to npm and test it manually by installing it into a sample project.

What you need is a way to test it locally to ensure that everything works correctly before publishing to npm. 3. npm v3.10.3 npm ERR! spawn ENOENT npm ERR! node v6.7.0 npm ERR! Failed at the UpScore@0.6.0 start script 'react-scripts start'. The build is minified and the filenames include the hashes. This is not advised, as you may end up publishing buggy code to the registry for other developers to consume. I have a Create React App, Single Page Application application. I created a new project with create-react-library. npm ERR! Test-run the npm module in-the-making while it is being developed using two techniques both, local test run* and parallel test run**. argv "/usr/local/bin/node" "/usr/local/bin/npm" "start" npm ERR! I found this to be true as well for React testing. Exit status 1 npm ERR! When I fire npm run build command, I get following error : npm ERR! UpScore@0.6.0 start: `react-scripts start` npm ERR! Register and publishing the npm module to nmp js. So I decided to just write a complete React testing guide in one article.
