硒测试对无头铬的测试失败 [英] selenium tests fail against headless chrome
问题描述
我正在尝试使硒测试自动化系统针对无头铬运行，以便将其移至TeamCity.我还没有运气.当我运行它时，Chrome确实可以无脑地运行(没有浏览器弹出)，但是我得到了NoSuchElementException.当无头运行时，自动化将按预期工作.拍摄的快照仅显示一个白色矩形.
I am trying to get my selenium test automation to run against headless chrome so that I can move it to TeamCity. I have not had any luck. When I run it, Chrome does appear to run headlessly (no browser pops up), but I get a NoSuchElementException. The automation works as expected when run non-headlessly. A snapshot taken just shows a white rectangle.
我已经对该问题进行了广泛的研究，但是找不到适合我的解决方案.看来该问题是在 https://bugs.chromium.org中报告的. /p/chromedriver/issues/detail?id = 476 ，但已标记为固定.我认为问题可能出在错误的chromedriver，或者错误的chromedriver/Selenium组合，但是我尝试了各种各样的组合，但是没有爱.
I have researched this issue extensively, but I have not been able to find a solution that works for me. It appears that the issue was reported in https://bugs.chromium.org/p/chromedriver/issues/detail?id=476, but it's marked fixed. I think the problem might be the wrong chromedriver, or maybe the wrong chromedriver/selenium combination, but I've tried all sorts of combinations and no love.
我正在使用:
- selenium-java 3.6.0
- chromedriver 2.33.506120
- Windows 7 Enterprise Service Pack1，64位
我的代码是:
...
ChromeOptions headlessOptions = new ChromeOptions();
headlessOptions.addArguments("--start-maximized");
headlessOptions.addArguments("--headless");
driver = new ChromeDriver(headlessOptions);
driver.get(url);
WebElement usernameTextfield = driver.findElement(By.cssSelector(".input.username"));
...
输出为:
Starting ChromeDriver 2.33.506120 (e3e53437346286c0bc2d2dc9aa4915ba81d9023f) on port 41402

这使我无法将我的测试自动化作为CI的一部分，因此，我们将不胜感激.
This is preventing me from being able to include my test automation as part of our CI, so any help would be very much appreciated.
推荐答案
这对我有用:
var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments("--headless");
chromeOptions.AddArguments("--disable-gpu");
chromeOptions.AddArguments("--window-size=1280,800");
chromeOptions.AddArguments("--allow-insecure-localhost");
//specifically this line here :)
chromeOptions.AddAdditionalCapability("acceptInsecureCerts", true, true);
