带有无头铬和硒的 NoSuchElementException

Question

I am trying to use headless chrome for our selenium tests and have made the below changes:

DesiredCapabilities desiredCapabilities = DesiredCapabilities.chrome();
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--disable-gpu");
options.addArguments("window-size=1800x1080");
desiredCapabilities.setCapability(ChromeOptions.CAPABILITY, options);

My test logs into an internal page and then waits for the element to be visible:

selenium.waitForElementVisible("xpath=//tr/td/div[@class[contains(., 'x-grid-cell-inner')] and text()='Global Test Merchant 14']");

This all works well when i do not have the headless option but i get :

org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element:  {"method":"xpath","selector":"//tr/td/div[@class[contains(., 'x-grid-cell-inner')] and text()='Global Test Merchant 14']"} 

when i run the test with --headless.

Chrome Version: 62.0.3202.89 chromeDriver: 2.33.506120 Selenium version: 2.53.0 Windows 7

Answer 1

我有同样的问题，我的错误是因为我正在制作 driver.get("localhost:...") 而不是 driver.get(" http://localhost :...")

Answer 2

I had a similar issue when I ran headless as well, my project while running headless continue to trigger the NoSuchElementException and the default-browser-check was getting in the way, try adding these arguments. Just a thought

chromeOptions.addArguments("--headless");
chromeOptions.addArguments("--test-type");
chromeOptions.addArguments("--disable-gpu");
chromeOptions.addArguments("--no-first-run");
chromeOptions.addArguments("--no-default-browser-check");
chromeOptions.addArguments("--ignore-certificate-errors");
chromeOptions.addArguments("--start-maximized");

Answer 3

当您看到NoSuchElementException 时，您可以考虑将xpath与服务员一起使用，以使元素可见，如下所示：

//tr/td/div[@class='x-grid-cell-inner' and contains(., 'Global Test Merchant')]

Answer 4

I had a similar issue.

I tried following options and it worked for me.

    options.addArguments("--window-size=1920,1080");
    options.addArguments("--disable-extensions");
    options.addArguments("--proxy-server='direct://'");
    options.addArguments("--proxy-bypass-list=*");
    options.addArguments("--start-maximized");
    options.addArguments("--headless");
    options.addArguments("--disable-gpu");
    options.addArguments("--disable-dev-shm-usage");
    options.addArguments("--no-sandbox");
    options.addArguments("--ignore-certificate-errors");

In my particular case I only had to use these 3 arguments to solve the same issue:

options.addArguments("--headless");
options.addArguments("--start-maximized");
options.addArguments("--window-size=1920,1080");
