@christian-bromann, to further improve this PR:

1. I think we won't need this anymore : L164-L174 ? (and it was not even conditioned to isUsingTypeScript)

2. We would need to add a default tsconfigFile value in angular.json L196:
   tsconfigFile: /test/tsconfig.e2e.json

   But I'm sure on how to get the /test here...

to further improve this PR:

seems reasonable, do you want to do this in a separate PR or in this one?

Any idea on how to elegantly get the parsedAnswers in here L188 ?

I need to do something like :

const relative = path.relative(process.cwd(), parsedAnswers.destSpecRootPath);
const tsconfigDir = relative.split(path.sep)[0];

const wdioConf = {
  builder: '@wdio/schematics:wdio',
  options: {
    devServerTarget: `${project}:serve`,
    tsconfigFile: `${tsconfigDir}/tsconfig.e2e.json`,
  },
  configurations: {
    production: {
      devServerTarget: `${project}:serve:production`
    }
  }
}

Shouldn't it be possible to store data in the SchematicContext object?

I don't think so...

And anyway runWizard and modifyAngularJson are running in a chain (L34) so we cannot make sure they both run in sequence. I will have to find a better way.

I won't be able to solve it without making many changes.

Running the wizard is optional so I cannot rely on the parsed answers that it returns.
The tsconfig file path has to be determined from within modifyAngularJson().
But this file could have been renamed or moved from a previous wizard installation, and so did the wdio configuration file.
So I'm kind of stuck here...

I guess the wizard shouldn't be optional (why would it be after all ?)
The schematics should decide itself whether wdio is already installed and install it if it's not or do nothing otherwise.
That way everything would be more predictable and easier to automate.

Unfortunately I'm acting blindely on this one because I was not able to mount this project locally to make the proper modifications.

I followed the development section in the README and it simply doesn't work.
