This project shows how to collect code coverage from Storybook (e.g. when using Chromatic for Visual Regresion tests) and how to create a combined report for 3 types of test:

• visual regression tests (storybook/chromatic)
• unit tests (jest)
• integration tests (cypress)

You can view a report for each type of test, or view the coverage of all tests together.

yarn yarn coverage open coverage/merged/lcov-report/index.html

You can also merge reports with codecov.

• Integration test report doesn't include full statistics for files with no coverage
• Can't configure cypress-specific nyc settings outside of generic files (package.json/nycrc)
• Can't currently use create-react-app 3.4.1 - facebook/create-react-app#8689
