helium's Issues

Element click does not take effect

Hi，
Sorry for interrupting you.
I click the login button on a page, most of the time it does not work,But when I add sleep or debug before clicking, it can take effect,as follows:

Do not hover dot

Good day!

Your project is amazing.
I liked the ability to hover over an element by coordinates.
But the problem is that for some reason do not hover on the coordinates that are below the browser window that I would not do.
What might be the problem?

I apologize for my poor English.

Error launching Chrome (latest version) and it's possible solution.

Hello sir,

Hope you're doing well in this pandemic. Though helium comes with it's own version of chrome driver and gecko driver, helium can't open the latest version of chrome 89.0.4389.____ . I think helium is using the old version chrome driver.

I hope you know that this can be resolved by downloading the latest chrome driver and replacing them in the necessary folder (\python__\Lib\site-packages\helium_impl\webdrivers\ _____ ).

It would be good if you can update them on your side so that, new folks like me don't get confused and don't need to spend hours searching how to resolve that issue. 😁

Thanks & Regards,
Shaik Fharook.

Sometimes click doesn't work

Hello,

I tried to use below code to click the second Courses on web page but some times it works fine, most of the time just throws me an error saying LookUpError.
click(find_all(Text("Courses"))[1])
I also tried to use click(S(selector="//li[@data-report='courses']/a")) but i got the same problem, the first time it works fine, but the rest times don't work. Anyone has any idea?

No function to open a window

Hi, really great work!
The only thing I miss is a function to open a new window in the browser.
You can identify windows and change them, but isn`t it be possible to create a new one? And in additional it would be also nice to can simply close one (not the browser)

Support dropdown list

Would it be possible to select or change dropdown list?

Helium find all

Is it possible please to use find all to find , say, the first 10 items from the list generated and then stop. The list of elements may be a very long one that requires a considerable time for the code to run. If so, would this be configurable to find the nth series of n items?

Required java libraries

Please i need helium java libraries/ maven dependencies for making standalone web automation project

Check current URL

Hey,

Again great package.
Is there any way to get the current URL? I have a login page and if the user login successfully he is redirected and I want to test that is redirected to the right URL.

Thanks.

how to use lambda in he.S(...)

code e.g.

import helium as he

class Scaffold(object):
    @classmethod
    def exists(cls, s, below=None, to_right_of=None, above=None, to_left_of=None):        
        if isinstance(s, str) and s:
            if s.startswith(('@', '#', '.', '//')):                
                if below and to_right_of and above and to_left_of:
                    pass
                elif below and to_right_of and above:
                    pass
                elif below and to_right_of:
                    pass
                elif below:
                    ret = he.S(s, below=lambda below: he.S(below) if isinstance(below, str) else below).exists()
                ......

The expected function of the last line of code:
if below type is he.S
ret = he.S(s, below=below).exists()
if below type is str
ret = he.S(s, below=he.S(below)).exists()

But I got the following error:

Ask, how to traverse the li node and get its text value or attribute value via helium?

My attempt:

import helium as he

li_data_list = he.find_all('.list-wrapper')
for i in range(len(li_data_list)):
    # I want to get the time text
    # try method 1, but nok
    driver = he.get_driver()
    time_text = driver.find_element_by_xpath("//div[@class='course-info']")
    print(i, time_text)    # but two output is the same value : "Time: 2021-6-2 20:30\nCourse: Unit 5-Lesson 7-ABC Music\nTeacher: Tom T\nStatus: Normal End"

    # how can I traverse the <p> <li> node and get its text value or attribute value via helium?

Expected output:

Is it possible to dynamically traverse the element in the dom tree and set the focus for specific element ?

I have the requirement to automatically traverse the html elements through the python scripts, then set the focus of the elements in turn, and trigger the key press event to access the corresponding URL of the element. The Demo is here. So i want to ensure this project whether satify my requirement , and look forward to your replay.

How to start a Firefox instance with a specific user profile?

Hi,
I am trying to figure out how to start a Firefox instance with a specific user profile. From command line it is possible by running
firefox -P default-relase

Similarly from selenium it is possible by running

profile = FirefoxProfile(<path\to\profile\>)
driver = Firefox(firefox_profile=profile)

Any idea on how to do the same with helium?

Chrome - Link('<link_text>') works in non-headless mode, but doesn't work in headless mode

I'm using start_chrome() on macOS, Google Chrome, chromedriver and helium are upgraded to the latest (stable) versions.

I have a script with a line

helium.click(helium.Link('<link_text>'))

to click on a hyperlink on a web page, which works perfectly except when headless=True is passed to start_chrome().

I'm not very familiar with the underlying selenium-python framework, so I'm not sure if I ask this question in the right issue tracker. :(

Is this a known problem of helium? Is there any way to make helium work with headless Chrome? Thanks!

Versions:

• Google Chrome: 87.0.4280.88
• chromedriver: 87.0.4280.20
• selenium: 3.141.0
• helium: 3.0.5
• python: 3.8.5

Is it possible to get the pixel color at coordinates (x;y)?

Hi,

I need to know the color of a given pixel within a canvas with Helium.

How to do it?

Thank you in advance!
Best regards,

Change Chromedriver Path

Hi,
So i have a Script that uses Chromedriver and i want it to run on Heroku, but the problem is that you need to change the Chromedriver path to something like that: options.binary_location = os.environ.get("GOOGLE_CHROME_BIN") and the Start needs to look like that: (executable_path=os.environ.get("CHROMEDRIVER_PATH"),options=options) (Thats code from Selenium).
Is there a way to do something like that?
Thanks.

suggested addition to Readme documentation, installation section

addition to installation instructions for helium

"helium" not available directly from the Anaconda/conda environment at present (oct 2021) - so users should follow this
advice on installing non conda packages

---

Additional info, though this can be obtained from the link above, so may be TMI

Installing helium via command-line conda

* activate the conda environment where you will be using helium (eg conda activate myscrapingarea)
* verify pip available in that conda environment (conda install pip)
* then within that conda environment issue regular pip command (pip install helium)

Note:- when using conda you use its environments, not the regular pip virtual environments

Ability to set download directory and disable download or open popup using Firefox

Helium really does a great job simplifying selenium interface and I like using it. However, I couln't manage to set a profile for Firefox in order to change download directory and disable download popup. I think these were essential features for me while using selenium. Are you planning to add this kind of settings to start_firefox and start_chrome just like headless=True option?

In vue, if the value of input is extracted, the value that is extracted is a null value. Is there any solution?

In Vue, the input tag usually does not have a value attribute,
If the value of input is extracted, the value is null. Is there any solution?

Link is matching partial text

I'm doing a simple click(Link("Algebra I", below="Biology")) to click dropdown links. There are two values in the dropdown that are similar.

Algebra I
Algebra I Elective

It keeps clicking the one with "Elective" in the text which is only a partial match. This is not the expected behavior is it?

How can I have it do a full text match and not partial? I've tried using xPath "//*/ul/li/a[text()='Algebra I']" but it seems to have difficulty finding this dropdown text for some reason.

UPDATE: I found the following workaround. Not ideal but it works.

links = find_all(S("//*/ul/li/a"))
    for link in links:
        if link.web_element.text == "Algebra I":
            # match found
            click(link.web_element)
            break

StaleElementReferenceException when matching elements exist in both iframe and main page

Hi, I have an SPA that I'm trying to do some automated testing with

helium works fine when the elements are in the main page, but the app uses AJAX to load some content into an iframe, so when I try to find those elements to click on, I get an exception

the following demonstrates the issue:

• I load the main page in the browser
• the main page of course has a body element
• the main page also contains an iframe element
• the iframe element contains another body element
• find_all looking for any body elements fails
• if I drop down into selenium, and manually switch between iframe and main body, I can resolve the body element correctly
• I think there is a bug when querying the element wrapper's web_element attributes when the selenium driver is switched to the wrong frame?

Hey man !

Nice job !
I was wondering if you support ARM devices like raspberry pi ?

Page TimeOut

How to configure Helium so that the page load takes, say, no more than 15 seconds, so that after that you can catch the exception and do what I need.
The setup method does not work, for several days I have not been able to work with the problem.

In addition, as I understand it, by default, the page load time is equal to the timeout time of the script, which makes it impossible to catch the exception and continue working.

Please tell me how to set the page load timeout?

                        </div>
        </div>
        </td>`

The "write("8", into=S("#effortforOwnWonSwon11"))" work, but it does not work when "start_chrome(url=url, headless=True, options=options)" and raise an error ‘raise LookupError()’

I am so upset for that, I have tried three methods to identifying HTML elements by id,class and xpath, but it all does not work when headless is set with “True”.

now I have no idea what I should do next

thanks in advance

Running Helium On Docker

Hi!
I Tried to run Helium on Docker but I just cannot get it done. I think that this is due to the fact that I cannot parse the chromedriver path. I have a docker container that runs selenium already. I though that by adding chromeOptions just the same would suffice.
This is the code I have:

options = ChromeOptions()
        options.add_argument('--disable-gpu')
        options.add_argument('--disable-impl-side-painting')
        options.add_argument('--disable-gpu-sandbox')
        options.add_argument('--disable-accelerated-2d-canvas')
        options.add_argument('--disable-accelerated-jpeg-decoding')
        dr = he.start_chrome(login_url, headless=True, options=options)

Do yo uhave any clue of my problem?

This is the error I get from Selenium:

DriverException('unknown error: Chrome failed to start: crashed\n  (Driver info: chromedriver=2.38.552522 (437e6fbedfa8762dec75e2c5b3ddb86763dc9dcb),platform=Linux 4.15.0-106-generic x86_64)', None, None)

Set chromedriver path in start_chrome

It would be nice if you could set the path to chromedriver in start_chrome, similar to the way you can pass options to it, for use in a container. (I spent most of the day yesterday trying to figure out why selenium can't find chromedriver even if it's in the path, and all I found was that it happens and people work around it, apparently.)

As far as I can tell, there's no way to pass the path in options, or am I missing something? One line is much better than seven lines to start chrome....

Could I use IE browser with helium?

I have a project just can be visit with IE browser, so i want to know, could i use IE browser with helium？

Helium cannot launch chrome inside AWS lambda environment

Recently we moved our Selenium UI tests to AWS Lambda and for this we switched to a lighter version of headless chromium as the default chromium is not compatible with AWS lambda.
Now we wanted to use Helium for our existing tests. Though we wanted to run our tests in headless chromium, we are getting "cannot Import name FirefoxOptions" exception when we tried running our tests with Helium inside AWS Lambda environment.
Please find screenshot with logs for the same.

Chrome version error while running in Travis-CI

First of all, thanks for this great package, tried selenium in the past and found it too complex.

I managed to use this package locally, but when trying to run in. Travis-CI, I'm getting the following error:

selenium.common.exceptions.SessionNotCreatedException: Message: session not created exception: Chrome version must be >= 65.0.3325.0

This is the code that I added to my project.
In .travis.yml:

dist: trusty
before_install:
  - google-chrome-stable --headless --disable-gpu --no-sandbox --remote-debugging-port=9222 http://localhost &
addons:
  chrome: stable

new test file (test_client.py) with:

# A Helium function:
from helium import start_chrome, kill_browser


def test_home_page_load(client):
    driver = start_chrome(headless=True)
    kill_browser()

What I'm missing?
Thanks.

How to set the window size...I'm a novice

Impossible to detect non-ascii text

Hello! Thanks for the awesome project. I really appreciate your work.

I'm trying to test the site with cyrillic letters.
Such code doesn't work:
write("Hey!")
I've made some investigations. The thing is that the api couldn't locate elements with cyrillic letters. So such pieces of code also doesn't work:
click('Войти')

To confirm this statement, I've made some changes to test_write.py

def test_write(self):
       write("Hello World!")
       self.assertEqual("Hello World!", TextField("Автофокус").value)

and test_write.html

<tr>
      <td>Автофокус:</td>
      <td><input id="autofocus" type="text" autofocus /></td>
</tr>

As expected, this test failed with LookupError. So this awesome simple api become useless.

Is there a way to fix this?

Running multiple instances in parallel

I've been using Selenium to run multiple browser windows in parallel. To do this I would simply start a new Chrome instance and place all the driver references into a list. I then send each instance to a thread to run through its instructions. However, it doesn't seem like this is possible with Helium as, as far as I can tell, there is just one global Helium instance and I need to set the driver before executing the command. However, when I run this in multiple threads, the wrong commands get called.

Is there to have multiple instances of Helium at one time?

Doesn't support the new Chrome 91 stable version

Hi, Helium doesn't support the new chrome 91 only 89 and returns error saying that.

Can you please show me how to update the chromedriver inside helium so it can support Chrome browser version 91 (stable, not beta or unstable). Without specifying the chrome driver too.

Is there a way to change the chromedricer directly inside Helium's files, without adding anything to the code.

Thank you

ingognito and window size setting

Is it possible to set chrome to use incognito mode, and also set the size of the window?

I know selenium can do this, but didn't find how to 'map' those options to helium.

I would like to add docs

First off wonderful project and a great job!
Even though the project's source code is well documented, I feel like the fact that there isn't any actual official docs for it turns people away. New users don't want to dive into source code to know what functions do.

My proposal:
I would like to add documentation to the docs/ directory using Sphinx. First I plan on adding the already documented methods to the docs and then move on to less documented ones.
Once I complete that, the project maintainer(s) can integrate these docs to readthedocs or to github pages. I have experience with both and can help accordingly.

Let me know what you think!
Looking forward to hearing from you.

How to do multiple select?

Hi,

I am trying to select more than one option from a multi select element.
Right now, I've achieved this by writing a select command for each option like

select(ComboBox('multi select element'), 'option 1')
select(ComboBox('multi select element'), 'option 2')
select(ComboBox('multi select element'), 'option 4')

Is there any better or easy way to do this?

Will it works for Microsoft Edge?

press method is not working

First of all, thank you for such an amazing tool. I really appreciate your time and effort on this project. I wish I could support your work on this. I know you said you won't respond to issues but I just hit a dead end and praying for your help :)

I am not sure what I doing wrong but whenever I use the press method to enter a combination, nothing happens but the method completes execution. For example, I tried press(CONTROL + SHIFT + 'r') to hard refresh the page and nothing happens. I tried press(CONTROL + 't') for a new tab and nothing happens. I thought it was just my machine and tried it on my friend's machine and got the same thing.

Once again, thank you so much for your time.

Takes 30 sec to click the window

Hello Sir,

Helium is AMAZING!

I just have a problom with the waiting time and hope to consult with you. My process is as below and I attached the Html file:

1. open a web
2. web will show a inner html area and I need to click the box with MyID.
3. done

In the step 2, it always takes 34-36 sec. It is possible to speed up? I am not sure if I use the wrong code.
I had tried:

     1. wait_until(Text('MyID').exists())
     2. wait_until(S("#login").exists())
     3. Config.implicit_wait_secs = 0
