webdriver.chrome.driver in headless mode can't find element #4477

plaidshirtakos · 2017-08-16T12:55:25Z

Meta -

OS:
Windows 10
Selenium Version:
2.53.1
Browser:
ChromeDriver 2.31.488763

Expected Behavior -

I initialized driver as shown below:

ChromeOptions chromeOptions = new ChromeOptions();
System.setProperty("webdriver.chrome.driver", "C:\\chromedriver.exe");
chromeOptions.addArguments("--headless");
driver = new ChromeDriver(chromeOptions);
driver.manage().window().maximize();

Given xpath belongs to an input field, which opens a file selector when clicked. It is working perfectly in a normal Firefox. I use WebDriverWait to wait until necessary elements appear.

wait.until(ExpectedConditions.presenceOfElementLocated(mainPage.InputFileField));

Actual Behavior -

I get following message, when I execute test:

Starting ChromeDriver 2.31.488763 (092de99f48a300323ecf8c2a4e2e7cab51de5ba8) on port 44655 Only local connections are allowed.

org.openqa.selenium.TimeoutException: Timed out after 30 seconds waiting for presence of element located by: By.xpath:

Steps to reproduce -

Please see code snippet.

Could you please share the xpath and the web page(or it's DOM) ?

barancev · 2017-08-16T19:50:40Z

Yes, please provide a concise reproducible test case

driver.manage().window().maximize(); doesn't work in headless mode. Try setting the window size directly.

For more info, see https://bugs.chromium.org/p/chromedriver/issues/detail?id=1901

@kumar-nitish : Xpath for this element look like this: //*[@id="form"]/p[1]/label
@jleyba : I tried to set it with --window-size=1024,768 too.

kumar-nitish · 2017-08-20T10:43:51Z

I created a dummy page and tested similar xpath with below config and it worked fine.

Win10 x64
Chrome driver v2.31.488763
Selenium 2.53.1
Chrome : v59 & 60 ( latest )
Xpath : //*[@id='form']/p[1]/input
HTML

<html>
<body>
    <form id="form">
        <p>
            <input type="file" name="inputFile1" />
        </p>
    </form>
</body>
</html>

@plaidshirtakos Could you please share your html DOM, chrome version and exact XPATH ?

plaidshirtakos · 2017-08-22T08:34:43Z

@kumar-nitish : //*[@id="formA"]/p[1]/label
Browser:
ChromeDriver 2.31.488763
<label class="forFileInput" for="fileUpA" multiple="">Choose file!</label>

kumar-nitish · 2017-08-22T18:20:59Z

Could you please follow below instructions and share the outcome

Create a html file with below code

<html>
<body>
    <div>
    <form id="form">
        <p>
            <label class="forFileInput" for="fileUpA" multiple="">Choose File!</label>
            <input type="file" id="fileUpA" />
        </p>
    </form>
    </div>
</body>
</html>

Download TestNg test case from https://gist.github.com/kumar-nitish/9d213cfcaac5c160b08a3816ebb7325f
Update the chrome driver and html page path in above code and execute it

plaidshirtakos · 2017-08-24T08:08:55Z

@kumar-nitish : I use the exact same code to cretae driver and get the following:

java.lang.NullPointerException

System.setProperty("webdriver.chrome.driver", Thread.currentThread().getContextClassLoader().getResource("C:\\chromedriver.exe").getFile());

kumar-nitish · 2017-08-24T15:45:10Z

My bad, that was because I was referring to chrome from resource folder. Use this instead

System.setProperty("webdriver.chrome.driver", "C:\\chromedriver.exe");

codebryo · 2017-09-13T16:14:20Z

@kumar-nitish I can at least verify that I run into the same kind of issue.
Headless chrome is not correctly picking up have_selector or has_selector or any other approach through Selenium to verify an element exists. I found a workaround though.
Not sure why, because it works on some elements and on some not.

Anyway, I ended up doing something like this (Note I am doing it in ruby)

# defined the method
def selector_exists(selector)
    page.execute_script "return document.querySelector('#{selector}').length > 0"  
end

# assert in the spec
expect(selector_exists('#form')).to be true

That at least solves it for now as the running js can verify it's there.

not able to find below element while running test automation in chrome headless using nightwatch framework.
element is a video stream.
div[class$='src-routes-room-content-streams-___streams__streams src-routes-room-content-streams-___streams__size1']

vasipower · 2019-05-01T05:11:13Z

Add below lines of code in ur main class

ChromeOptions options = new ChromeOptions();
options.setHeadless(true);
options.addArguments("--window-size=1920,1080");
options.addArguments("--disable-gpu");
options.addArguments("--disable-extensions");
options.setExperimentalOption("useAutomationExtension", false);
options.addArguments("--proxy-server='direct://'");
options.addArguments("--proxy-bypass-list=*");
options.addArguments("--start-maximized");
options.addArguments("--headless");

WebDriver driver = new ChromeDriver(options);

@vasipower This issue has been closed for over a year

Also.. don't just arbitrarily recommend Chrome options without explanation... it's harmful to any users that might mistake this as a solution.

mushroomlb · 2019-05-10T09:15:55Z

I met the same situation. After studying, the following is correct：

self.chrome_options = webdriver.ChromeOptions()
self.chrome_options.add_argument("--window-size=1920,1080")
self.chrome_options.add_argument("--disable-extensions")
self.chrome_options.add_argument("--proxy-server='direct://'")
self.chrome_options.add_argument("--proxy-bypass-list=*")
self.chrome_options.add_argument("--start-maximized")
self.chrome_options.add_argument('--headless')
self.chrome_options.add_argument('--disable-gpu')
self.chrome_options.add_argument('--disable-dev-shm-usage')
self.chrome_options.add_argument('--no-sandbox')
self.chrome_options.add_argument('--ignore-certificate-errors')
self.browser = webdriver.Chrome(options=self.chrome_options)
