[💡 Feature]: Support configuring NODE_OPTIONS for ChromeDriver separately from NODE_OPTIONS for WDIO itself about webdriverio

[tanin47]

Sounds good. I'm happy to make the change!

Today NODE_OPTIONS for WDIO is carried over to ChromeDriver; in turn, it is carried over to Electron (dev mode), and Electron crashes because of it.

Can you be more specific on this section? I don't quite get why certain environment variables available when starting Chromedriver cause Electron to crash.

I would also consider adding shell: true, so it closely resembles when the Electron is started directly from command line.

How is starting Electron related to starting Chromedriver?

Thank you.

How is starting Electron related to starting Chromedriver?

ChromeDriver starts Electron, and I think the shell env is likely carried over to Electron when ChromeDriver starts Electron, but I don't have a way to confirm this.

I also added in the below to the post:

Specifically, WDIO sets NODE_OPTIONS=' --loader ts-node/esm/transpile-only --no-warnings' (ref), which is carried over to ChromeDriver and, thus, Electron.

To verify the impact of this env, we can run: NODE_OPTIONS=' --loader ts-node/esm/transpile-only --no-warnings' ./node_modules/.bin/electron in Terminal, and Electron will crash.

Thanks for clarifying! I think the best solution would be to just filter out NODE_OPTIONS as you mentioned in your alternative approach. Until we don't really have a reason why someone would need to control extra env vars for Chrome/Electron we shouldn't add any complexity.

Any contributions would be appreciated.
