runEventTimingFunction (Log Application Performance)
Compatible with:
- Purpose
- This command is used to get the performance timing metric for key events like DOMLoad, PageLoad, etc. using pre-built (Worksoft SaaS natively supported) javascript functions based on the Resource Timing API that many browsers support. If you want to use your own JavaScript functions instead use the command 'runScript' to execute your custom JavaScript function and then log the return value from those functions by using the 'setEventTiming' command.
