I'm trying to write automation for memory leak testing of a website. I can see a memory leak by going between two pages so I have selenium automate going back and forth between them. Before the process, after each iteration of going between those pages, and after ~150 repetitions I want to know how much the memory usage of each browser changes.
Using chrome as an example I tried using
tasklist | find "chrome.exe" and totaling up the memory usage output for all those processes. I'm not sure if I'm doing something wrong or if it's giving me different data than I'm thinking it's supposed to, but
tasklist is giving me different numbers than Task Manager for memory usage.
Just trying it now the total memory usage between all the chrome.exe entries in
tasklist showed 1259MB, but task manager shows ~530MB. Additionally after doing 150 iterations
tasklist yesterday was showing ~1800MB (and memory usage had plateaued and didn't go any higher) but Task Manager was showing ~3300MB used and still going up. Closing that tab dropped chrome's memory usage in Task Manager to ~700MB. If left to run longer the browser would eventually crash, so the signs of a memory leak can't be seen using
tasklist as I am, but can be seen in Task Manager.
tasklist and Task Manager giving different measurements? Is there a way I can get the numbers Task Manager is providing from the command line so I can automate it? I was experimenting with
