},What happened?
I'm currently migrating my codebase to use @wdio/cli instead of using child_processes to execute the wdio command.
After migrating the code to use wdio/cli, I'm seeing that it works on linux and mac but fails on windows and the failure is around session not getting created.
What is your expected behavior?
Session is not getting created specifically in windows when I use the Launcher method i.e. @wdio/cli
Expected behaviour is for the session to get created and test to run.
How to reproduce the bug.
create a minimal wdio.conf file with the capability attached above run tests via the following script in windows:
import { Launcher } from '@wdio/cli';
async function runTests() {
runnerOptions.spec = ['test.spec.js'];
const wdio = new Launcher('wdio.conf.js', runnerOptions);
wdio.run().then(
async (code) => {
process.exit(code);
},
async (error) => {
logger.error('Launcher failed to start the test', error.stacktrace || error);
process.exit(1);
}
);
}
runTests()

I'm not sure why session creation is failing all the time specifically in windows while it's passing for mac and linux.Code of Conduct
