1. Create an app with CRA 2. Add the coverage threshold in the package.json file "coverageThreshold": { "global": { "branches": 90, "functions": 90, "lines": 90, "statements": 90 } } 3. run the command - npm test -- --watchAll=false --coverage 4. We can see "index.tsx" is not covered and the "threshold not met" messages in the console. But the script is not failing.
