I'm using webdriverIO for some automation testing and have recently migrated from 'selenium-standalone' service to default wdio devtools protocol.
From that point I can't start testing with firefox browser:
INFO @wdio/cli:launcher: Run onPrepare hook
INFO @wdio/cli:launcher: Run onWorkerStart hook
INFO @wdio/local-runner: Start worker 0-0 with arg: run,wdio.conf.js
INFO @wdio/local-runner: Run worker command: run
...
INFO devtools:puppeteer: Initiate new session using the DevTools protocol
ERROR @wdio/runner: Error: Couldn't find executable for browser
...
INFO @wdio/cli:launcher: Run onComplete hook
I've tried different combinations of options with 'wdio:devtoolsOptions' and 'moz:firefoxOptions'.
Plus checked whether could help dumpio: true, and 'moz:debuggerAddress': true options.
Also I've tried substitution browserName with product and adding binary and executablePath to capabilities.
When passing binary: 'path.to.firefox' to 'moz:firefoxOptions' options, the error message changes to:
ERROR @wdio/runner: Error: Only Nightly release channel is supported in Devtools/Puppeteer for Firefox. Refer to the following issue:
...
Any ideas how it could be fixed in webdriverIO (without installing separately puppeteer or puppeteer-firefox)?
Thanks!
Seems that I took desired for real.
wdio + devtools:puppeteer still work with Firefox Nightly only – https://github.com/webdriverio/webdriverio/discussions/7916
