test cases coverge `coverage.Icov` is empty

See original GitHub issue

I tried cloning and running test coverage but coverge.Icov is empty.

Steps to reproduce:

  1. clone and npm install

  2. npm run test:cov

    All test cases succeed but coverage looks like this in the terminal

File      |  % Stmts | % Branch |  % Funcs |  % Lines |Uncovered Lines |
All files |  Unknown |  Unknown |  Unknown |  Unknown |                |

and the coverage.Icov file is empty

Absolutely. It’s a race to the PR! 😄

This days I’ve been working on the issue and for now I am stuck and perhaps need some help or advise. For now I have managed to change config of the nyc (istanbul cli) as shown on the picture below: screen shot 2017-12-12 at 11 21 18 am and all the src folder files appear to be in the report but with some kind of strange coverage results screen shot 2017-12-12 at 11 21 36 am

Current investigaton and nyc/babel/istanbul issues checking didn’t point at the idea of what could have happened here. Any ideas from anyone where to point the attention to? Original changes can be found in the fork
