Tests

Unit

yarn test

Code coverage is saved in coverage folder. Open HTML report for example with

open coverage/lcov-report/index.html

End-to-end

Using Cypress test runner. Start dev server and open Cypress using

yarn dev

All tests are in the cypress/integration folder. These tests also collect code coverage and save in several formats in the coverage folder. Open HTML report

open coverage/lcov-report/index.html

Read Cypress code coverage guide

Note: to avoid inserting babel-plugin-istanbul twice during Jest tests, E2E tests run with NODE_ENV=cypress environment variable. The babel-plugin-istanbul plugin is included in .babelrc file only in the cypress Node environment, leaving the default Jest configuration during NODE_ENV=test the same.
