Istanbul coverage nested directories in HTML report

Question

The unit test coverage report from Istanbul in HTML format displays every single folder of the project in the index.html.

It actually flattens the directory structure. Is there an option to render the html report with nested folders?

Answer 1

If you use the coverage reporter attribute with 'lcov', it should be possible to view using a tool. It does give a folder structure. eg: https://lcov-viewer.netlify.app/report
