I have started from scratch several times and cannot seem to get e2e test coverage using Angular 18, cypress, @cypress/code-coverage, @cypress/schematic, nyc (aka: Istanbul), etc.
It does seem to be instrumenting the code because I get data in .nyc_output/ as a dynamically generated file…
…but the data never moves to .nyc_output/out.json…
I’m guessing this is what @cypress/code-coverage is using because the reports are empty…
Cypress also throws an error saying Did you forget to instrument your application?…
I have read all the documentation I can find and followed all the guides trying various techniques. I have yet to find a working example for Cypress e2e testing code coverage with Angular 18. Are they even compatible?
