public class XltChromeDriver
extends ChromeDriver

An extended ChromeDriver which allows to record data about requests and browser events or to run Chrome with a virtual display.

Collected Data

To collect data about requests and browser events, a special extension will be installed into the browser. This extension provides access to the following information:

• for requests:
  • start and total processing time
  • URL, status code, response content type
  • sent and received bytes
  • network timings (DNS time, connect time, send time, server busy time, receive time, time to first byte, time to last byte)
• for browser events:
  • the time after which the event occurred when loading a new page

The following browser events will be reported:

• DomLoading
• DomInteractive
• DomComplete
• DomContentLoadedEventStart
• DomContentLoadedEventEnd
• LoadEventStart
• LoadEventEnd
• FirstPaint
• FirstContentfulPaint

All this data will be available in the XLT load test report. Request data is shown in the Requests section and browser events can be found in the Page Load Timings section.

Headless Mode

On Unix machines, it is possible to run the browser in "headless" mode, i.e. with a virtual display. To put the browser in headless mode, simply set the following property in the configuration of your test project:

 xlt.webDriver.chrome_clientperformance.screenless = true
 

Note that for the headless mode to work, the xvfb binary must be installed on the target machine and must be findable via the PATH variable. If this is not the case, the browser will be run with the default display.
