ChromeDriver does not exit at the end of tests

[troppoli]

I'm on windows 10, node 14.9.3.

You cannot run

npm run test

twice because the chomedriver process does not exit. You have to manually kill the process. I was experiencing this in the project I'm migrating to wdio and wdio-electron-servic. I'm not sure if it's a configuration problem or a wdio-electron-service issue.

PS C:\gitlab\wdio-electron-service-example> npm run test

> wdio-electron-service-example@1.0.0 test C:\gitlab\wdio-electron-service-example
> wdio run ./wdio.conf.js || (cat ./wdio-logs/wdio-0-0.log && cat ./wdio-logs/wdio-chromedriver.log && exit 1)

I ended up hacking in a onComplete in my wdio config

onComplete: function(exitCode, config, capabilities, results) {
    // we should not have to do this, and the ts types don't jive with the doc above about promises.
    simpleExec('START /wait taskkill /f /im chromedriver.exe')
}
