That programmer's high...

I've spent hours, spread over days, on some #$&#$!*@!^#!* issue with Selenium and Protractor. I had a test that sometimes worked fine (mostly the first two or three times) and most of the times didn't. Searching, rewriting, waiting, logging, nothing seemed to help... I already found the server looped infinitely trying to get an element on my page. And just now, I noticed the server always started looping at the same spot (which was pretty hard to see and remember sometimes it didn't loop at all and everything just worked). So I fetch an element, click a button which removes the element from the DOM and then wait for the element to be removed from the DOM. I guess sometimes the element removing would be a bit slower and the waiting occurred before the removal (it's all JavaScript multithreading/callbacks/promises, yuk...). However, when the element would be gone before the waiting commenced the waiting would try to fetch the element to get it's status, couldn't find it, tried to find it again, couldn't find it, tried to find it again... Fixed by just waiting a second. So glad I've FINALLY found that issue! Time to celebrate :D

With a glass of DOM perignon, no doubt.

What do you get when you cross a joke with a rhetorical question? The metaphorical solid rear-end expulsions have impacted the metaphorical motorized bladed rotating air movement mechanism. Do questions with multiple question marks annoy you???

Shouldn't that be "Definition of Madness"? :)

If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack. --Winston Churchill

Coincidentally, "Dom" is also the Dutch word for "Dumb" :D

Hold still Mark. We're going to have to hurt you now. :rolleyes:

So your "wait to see if the element is removed" would loop forever because it couldn't find the element if the element was already removed? That is just too weird. But congrats on finding the problem! Marc

Exactly.

That's why it took me so long to find :laugh:

Do I understand this right -- you "fixed" the bug by waiting a second instead of polling the element's status?

We can program with only 1's, but if all you've got are zeros, you've got nothing.

Had similar problem reading paper tape input where the next read executed before the last read's physical movement had ceased. Wait of 1/10th second fixed it. In 1965 I think.

Glad to hear it. So everyone's invited to the bar Friday night? Sander's buying! :laugh:

Sander Rossel

Yeah, because polling the element's status wasn't going to work. Mind you, this is third-party software behavior. If it were my own I'd fix the infinite loop instead. Anyway, if this task takes longer than a second that's probably a bug too.

Or its running on someone else's machine :) Poorly written third party software is the worst. Glad you found a way around them.

Selenium is an open source automated testing suite for web applications across different browsers and platforms. Selenium is one of the widely used automation testing tools because of its various advantages. Testers prefer Selenium over any other tool due to its ease of use, availability and simplicity. Testers lives have been made easier with the Learning of selenium for automated testing. It has attracted many eyeballs and become a favorite tool among automation testers.
