How to write a script in Javascript for getting a browser performance data with using jp@gc webdriver plugin

[ino...@gmail.com]

Hi, All

I write a script for getting a browser performance data with using jp@gc webdriver plugin/javascript

but some exceptions occur and I couldn't get performance log.

It (performance log) means Chrome developer tools' network tab and timeline tab data.  

In addition, I found out some web page knowledge resource but I couldn't find out javascript sample code.

Anybody help?

My  jp@gc Webdriver Sampler code:================

//import

var pkg = JavaImporter(

    org.openqa.selenium

    ,org.openqa.selenium.support.ui

    ,org.openqa.selenium.remote

    ,java.util.Arrays

    ,java.util.logging

    ,java.util.Map

    ,org.openqa.selenium.chrome

    ,org.openqa.selenium.logging)

var capabilities = pkg.DesiredCapabilities.chrome()

var logPrefs = {'browser':'ALL','driver':'ALL','performance': 'ALL'}

var options = {perfLoggingPrefs:{traceCategories: 'v8,blink.console,disabled-by-default-devtools.timeline'}}

capabilities.setCapability(pkg.CapabilityType.LOGGING_PREFS, logPrefs)

capabilities.setCapability(pkg.ChromeOptions.CAPABILITY, options)

WDS.sampleResult.sampleStart()

WDS.browser.capabilities = capabilities

WDS.browser.get("http://www.sample.com/")

var logEntries = new pkg.LogEntries(WDS.browser.manage().logs().get(pkg.LogType.PERFORMANCE))

logEntries.forEach(

    function(entry){

        WDS.log.info(entry.getTimestamp() + " " + entry.getLevel() + " " + entry.getMessage())

    }

)

WDS.sampleResult.sampleEnd()

My environment:================

OS:windows 7

Java : 8

JMeter ver : 3.2 --<<use>>--> plugin manager--<<use>>-->Selenium/Webdriver support

Borwser : Chrome latest

JMeter setting:

 ThreadGroup 1user 1iteration + jp@gc Chrome Driver (is set chromedriver.exe)

Thanks

even i am trying to get the same. Do you have any luck?

DesiredCapabilities are used for browser instance creation and they are immutable (cannot be changed in the runtime). So consider the following alternatives:

1. Execute JavaScript in order to access window.performance object and query i.e. Performance.timeOrigin / Performance.navigation data
2. Switch to JSR223 Sampler and Groovy language so you will be able to instantiate your own WebDriver implementation with whatever capabilities you want so you will not have to rely on the defaults hard-coded into the WebDriver Sampler plugin

any luck on this code ? i have a similar requirement in my project . let me know if you have leads with this issue

If you upgrade your WebDriver Sampler to the latest version using JMeter Plugins Manager you should see Capabilities Management tab, you can set whatever Capabilities you want there
