What do you mean with display? Browser window?

in order for chrome to run on a headless server jimboslice-sl

you need to h ave xvfb running so it simulates a display.

You can look at the docker-selenium containers

afaik they use the same display

i'll look, thanks.

Is it possible to get selenium / webdriver.io visual regression testing fast? Like during a live-reload? Or I guess I just run the visual regression testing sometimes or "slow" on the build server, to make sure nothing is broken

I was hoping to run some visual regression testing fast whilst coding, to ensure browser compatibility (currently live reloading many browsers on a 4k screen with just browsersync, getting < 1sec browsersync. And just looking at it with my eyes."

I need to run multiple tests (10) on a headless server.

I am debating between phantomjs and dealing with the memory leaks, or xvfb and chromedriver.

any suggestions?

I have tried both approaches, they are both cpu hogs.

I've been using https://hub.docker.com/r/elgalu/selenium/ for about a year for Chrome testing, and I've been really happy with it

But yes, it's a CPU hog :)

I just am not sure if I can optimize anymore..

I think headless chrome is very close

I just saw someone mention a few days ago that they actually have it running (maybe in Chromium instead of Chrome)

I have headless chrome running, bu t it won't sendkey unless I have xvfb running.

ah

Can you think of another way to enter something into a field without send_key()?

I

that is literally the only issue I have with it.

billagee-sl, was that a typo?

the bit about setting an element's value attribute? Trying to find an example in case I'm not remembering correctly

maybe this?

I also had to mimic send_keys() via a JS call at one point on some OS/browser combo that had an issue

not sure if I still have that code around anymore, though

ah, this looks familiar

billagee-sl, it is within a textarea that I need to "send" the key to.

I often read the value of an input or textarea with `get_attribute('value')` ... I think it's pretty easy to set a value too

billagee-sl, do you have any example of entering something into a textarea?

hm, I found one example that was for an input element, but would probably work with a textarea - only issue is it depends on jquery :(

thanks

i'll give it a try

But every web app I've worked with at my last two jobs had jquery available, so maybe it's not a big deal

no prob!

billagee-sl,

I think it might very well work.

However, how can I within an execute_script parametize it?

so the "value" is something provided by the script and not hard coded.

I think you can prepare your JS expression a bit like that example above, before you execute it

and then pass it to execute_script ... as in this Python snippet: `"$('textarea[name=foo]').val('%s')" % some_variable`

Although I guess these days Python people use the style `"$('textarea[name=foo]').val('{0}')".format(some_variable)` :)

help

jyothi: :clarify

Please clarify: Are you using WebDriver, RC or IDE? What version of Selenium? What programming language? What browser and browser version? What operating system?

IDE

selenium-server-standalone-3.0.1.jar

wat

jyothi: the standalone jar is for webdriver

not IDE

and you didnt answer all the questions

Hi, I am new to selenium, My project is in IE and facing this issue Unable to find element on closed window (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 40 milliseconds

Please provide me some solution, i am blocked due to this error message

Gachi: it literally says whats wrong, you tried to find an element on a window that you previously closed

i tried to find element but with IE element is not getting identified

Gachi: please read what i said

do you know what an element is?

yes im trying to identify using different way like id,class,xpath

Gachi: do you know what a window is?

same code is working fine in firefox

im not getting you

Is it possible to run automated seleniumHQ with screen locked windows?

jumper: yes

Gachi: your error says what’s wrong. It says you tried to find an element on an IE window that was closed.

A window is just a browser window

So for some reason you’re either closing the window you’re working on, or IE crashes and closes it, or you’re trying to operate on a window you switched to earlier that doesnt exist anymore

Do you know how to do please?

jumper: you mean using webdriver?

or using IDE

yes

webdriver

jumper: set it running and lock?

ive done it before

i dont think there’s any guarantee that it will work, on all browsers, but ive definitely done it before

maybe i should have been more clear there

jumper: if you rather want to run tests on no screen, u can try to run on a linux machine using xvfb

I've tried by this way but it doesn't work..

or using chrome headless mode

ok so on windows, it's not possible to launch test with lock screen?

I can able to see the browser and my browser is active, any suggestion?

what is chrome headless mode?

Gachi: wild guess: you have two driver instances and you mixed them
