we're testing a web application, with components in java as well as flex, and we want a good way to measure page load times. anyone have a good suggestion? we're struggling a bit because flex removes quite a few options out of the mix. ideally we would want this solution in qa environments as well as in production post-release.
maybe an automation tool providing commands like "waitForElementPresent" (target should be the content sent by the ajax things) can help you. So when the this wait-cmd triggers true you could end the testcase or record the time in some other way.
i'm just a trainee right now using XLT, which is an automation tool for load-/regression-test. it's based on selenium i think (which i haven't used) so maybe one of them could help you.
maybe you already have such a tool and could use such a waitFor-command for your purpose. i use them often, let's say you want to wait for the new value of a span (e.g. different price when changing a dropbox-selection, say old price is 5, new one is 10), so my cmd would look like:
waitForElementPresent(xpath=//span[@name="price" and contains(.,"10")])
waitForElementPresent(xpath=//span[@name="price" and @value="10"])
i hope i could help. maybe your application is too complex for this, then i have no idea (as i am just a trainee [img]/images/graemlins/wink.gif[/img] ).
