How to use with Unit testing with Karma

[inggil2407]

I want to create unit testing but, always get "Uncaught Error: Cannot find module "@app/env""

When I try to start karma unit testing, console shows errors: Module not found: Error: Can't resolve '@ app/env' in...

P.S. Compiling and building works as it should (ionic serve, ionic build cordova, ionic cordova compile, ...).

Hi,

You need to tell webpack where to find (resolve) the app/env files... I guess you have a webpack.test.js somewhere, if so, update the resolve block to look like this.

resolve: {
    alias: {
      '@app/env': path.resolve(environmentPath('dev'))
    },
    extensions: ['.ts', '.js']
  },
... 

Define your environmentPath function to return the path to your env config as in the README of the project. You can even extract it into a env-helper.js file outside of the webpack configs to avoid code duplication, and require your helper.

Hope it helps ;)

I am going to close this as it seems to be resolved. Thanks!

@gshigeto This info should probably be added to the README as it's likely the majority of people will be using unit tests and this needs to be inplace in order to make them work.
