POSelenium FluentWait wait before starting to poll
text
Body
copied!<p>I'm using Selenium WebDriver to get some content from a site that dynamically loads it using Ajax. I created a custom Wait class to check for a condition on the page to make sure that the page has loaded before continuing. I used FluentWait to set the polling interval to 2 and timeout to 10. However, I noticed that it checks for the first time at time increment 0, then waits 2 seconds if the condition was false, then checks again, etc. </p> <p>Since the page takes <em>some</em> time to load, it always is false at the first check, but usually is true at the second. Is there any way to make Wait wait the 2 seconds <em>before</em> checking for the first time? I.e. check at times 2,4,and 6, if necessary, rather than at 0,2,4,and 6?</p> <p>Thanks, bsg</p> <p><strong>EDIT</strong> I've been asked to mention <em>why</em> I want this behavior - after all, I'm using the Wait the way it's meant to be used. The benefit I get from it returning true the first time is the following: WebDriver apparently opens a new socket every time it issues a command to the browser. For whatever reason, these sockets don't always get closed after the call executes. When executing a large number of calls in a short time (for instance, when repeatedly checking for a condition, which is what Wait does), it is possible to run out of virtual sockets, and the driver crashes. (The lack of enough virtual sockets seems to be a known issue on Windows 7, but I can't modify my system.)</p> <p>The fewer calls to the driver I issue in a short period of time, the less likely it is to overrun the number of available sockets. I have observed that the first check <em>never</em> returns true, and therefore it's just opening a socket for no reason, making the program more likely to crash. That's why I want to wait. I hope this explanation is helpful for someone searching for information as to why they keep getting SocketExceptions in WebDriver. </p>
