I added the schematics and tried run the e2e tests. However, there was an error where it said error parsing the config file.

I am using Node 14.17.5 and Angular 12.2.8. Any help is appreciated!

I have the same problem. Seems to me, it's caused by the command using the tsconfig from the root of the project, instead of the e2e one that is created.

The sandbox example project doesn't have any problems, because its tsconfig defines "module": "commonjs",. Your (and my) project probably have a different value here.

I am not sure if fixing this is something the schematics should do, or if it's the responsibility of the project that implements them, curious about opinions on this.

@jordydejong @HymanZHAN can you provide some WebdriverIO logs?

I'm facing the same issue. The exact error I'm getting is

ERROR @wdio/config:ConfigParser: Failed loading configuration file: /<path>/wdio.conf.ts: Unexpected token 'export'
Unexpected token 'export'

It seems like the configured module in tsconfig.json (es2020) isn't compatible. If I use with "commonjs", webdriver.io works but not the ng test target. Also, I don't want to change the whole project because of the testing framework being used. Additionally, It seems that using individual ts config files for angular targets is not possible at that stage.

I'm using angular 12.2.10 and webdriver 7.14.1

@christian-bromann please tell me what logs are you looking for

please tell me what logs are you looking for

This error above is all necessary to know. Am I assuming right, that your project is using pure ESM? This could be problematic because WebdriverIO doesn't support this yet. It is on the roadmap.

Recommend to have a separate tsconfig file that compiles to cjs. You can configure the location of that tsconfig file in autoCompileOpts.

The main issue here is that wdio is not able to parse wdio.conf.ts -> Unexpected token 'export'

Using autoCompileOpts in the configuration file won't work as we can't parsed the file... ^^'

So I was thinking about exposing a new option tsconfigFile in the schematics schema and use that option to pass down the autoCompileOpts.tsNodeOpts.project to the wdio launcher. That way the launcher would knows the tsconfig prior to load the wdio.config.ts and things would work.
