Debug Selenium Tests: logLevel
Part 1
Environments
This tip works if you're targeting:
- a local MediaWiki
- a remote wiki
- continuous integration
logLevel
Change logLevel in tests/selenium/wdio.conf.js from the default error to info.
tests/selenium/wdio.conf.js
exports.config = { // Level of logging verbosity: trace | debug | info | warn | error | silent logLevel: 'info' };
Run Selenium tests
npm run selenium-test
Output will contain a lot of useful debugging information.
