Define path to package.json

[daribock]

Is your feature request related to a problem? Please describe. The project I am working on uses kotlin for the backend and therefore the ui is in a seperate folder and the package.json is therefore not in the root of the project. This is why I am getting errors when running the tests.

Describe the solution you'd like My suggestion for this solution would be either one of these two options:

1. Auto detect package.json
2. Option to manually define the path to package.json
