It will also create an example script that you can run right away! Using the test runner To install the test runner for use in an existing web app, please run: npm i --save-dev magnitude-test && npx magnitude init This will create a basic tests directory tests/magnitude with: magnitude.config.ts : Magnitude test configuration file : Magnitud...
