Using Angular CLI to Add WebdriverIO Results in Error and Can't Run Tests

[mylifeandcode]

Under Angular 14.1, I ran ng e2e and went through the prompts to install the schematics for WebdriverIO. But at the end, I had an error:

Configuration file was created successfully!
To run your tests, execute:
$ npx wdio run test/wdio.conf.ts

ENOENT: no such file or directory, open 'C:\DevPOC\Angular14App\wdio.conf.ts'

This was on an Angular 14 app without any real implementation (basically, just what the CLI creates for a new app). I created another new app and tried again, with the same result.

When I actually try to run the app using npx wdio run test/wdio.conf.ts, I get the following:

C:\DevPOC\Angular14App\test\wdio.conf.ts:1
export const config = {
^^^^^^

SyntaxError: Unexpected token 'export'

Steps to reproduce:

1. Use ng new to create a new app with Angular 14.1.
2. Run ng e2e to add the WebdriverIO schematics.
3. Check output for error message at the end.

Fwiw, I was able to solve "Unexpected token 'export'" issue by installing @wdio/cli . However, I was hoping the @wdio/schematics would have done that.

The above issue exists on Angular 15 too.

Even when I manually update angular.json and attempt to run ng e2e, I encounter an error that the wdio/cli cannot be found (even though it's there).

If it helps, I'm using Typescript and I have my project type set to "module" (ESM). I don't want to deviate from this because I like the typings I get in the wdio config file.

Same here, out of the box, accepting all defaults on ng e2e fails to run with the above problem, also on NG 15

Also exists on Angular 16.

I had to do a few things.

• run npm install @wdio/cli --save-dev as suggested by @richardeschloss
• After the first run, the wdio.conf.ts is dropped into the test/ directory regardless of where you tell it your files are. Move this to the root of the project.
• run again selecting the same options, and things will work all the way through and the build config is added to angular.json with the name wdio-run - rename this to e2e to fall in line with Angular and to prevent subsequent runs of ng e2e from clobbering your config.
• Open up wdio.conf.ts - running twice creates two copies of the tsconfig for the e2e tests. The first run will create test/tsconfig.json which will be incomplete, and the second creates test/tsconfig.e2e.json which is complete. It also adds the autoCompileOpts to the wdio.conf.ts twice. I removed the first one and kept the second which pointed to the more complete tsconfig.e2e.json

Now it runs. I get a Launcher is not a constructor error, but that's likely just more post config needed.

According to webdriverio/create-wdio#306 you can set type: module in your package.json.
