ERROR:process_metrics.cc NOT IMPLEMENTED error

问题:

Recently, we've started to get these kind of warnings on the console when running Protractor tests:

[12252:14584:1207/223118.187:ERROR:process_metrics.cc(105)] NOT IMPLEMENTED
[12252:14584:1207/223118.187:ERROR:process_metrics.cc(105)] NOT IMPLEMENTED
[12252:14584:1207/223318.188:ERROR:process_metrics.cc(105)] NOT IMPLEMENTED

It feels like they happen randomly but doesn't affect the test execution.

The only problem is that they pollute the output console making it more difficult to keep track of tests being executed and test results reported by jasmine/protractor.

Is there a way to turn off this kind of chromedriver warnings?

Using Protractor 5.2.2, ChromeDriver 2.34.

We've found this --silent flag that can be passed to chromedriver executable, but could not find a way to configure protractor to pass this flag when launching chromedriver..

It seems to be an issue with chrome v63

回答2:

You should be able to pass the --silent flag to chromedriver in your conf file. Something like:

capabilities: {
    browserName' : 'chrome',
        'chromeOptions' : {
            args: ['--silent']
        }
    }
}

"This warning message was generated by a bug in Chrome v63.

Upgrading to v64 (64.0.3282.167 as of this morning) resolves it."
