Question

以下是遇到的“魔法”处理：代码在Ubuntu 16.04，Ubuntu 15.10上运行正常，有错误：

org.openqa.selenium.WebDriverException: Error: Permission denied to access property "navigator"
org.openqa.selenium.WebDriverException: Error: Permission denied to access property "document"

我有以下代码：

import geb.spock.GebReportingSpec
import geb.waiting.WaitTimeoutException

class LoginSpec extends GebReportingSpec {
    def "#0 go to login FB"() {
    when:
        browser.go("https://www.facebook.com/")
    then:
        delay(9)
        if (browser.title != "Facebook") {
            browser.title == "Facebook - Log In or Sign Up"
            browser.currentUrl == "https://www.facebook.com/"
            waitFor(30){
                $("#loginbutton").size() == 1
            }
            $("#email").value(Config.FB_USERNAME)
            $("#pass").value(Config.FB_PASSWORD)
            println("entered credentials")
            $("#loginbutton").click()
        }
        delay(9)
    }

    void delay(Long seconds){
        try {
            waitFor(seconds){ }
        } catch (WaitTimeoutException ignored){ }
    }
}

GebConfig.groovy：

import org.openqa.selenium.firefox.FirefoxDriver

waiting {
    timeout = 2
}
environments {
    firefox {
        driver = { new FirefoxDriver() }
    }
}
baseUrl = "https://google.com"
testReportDir = new File("$buildDir/test-reports/UT")
testResultsDir = new File("$buildDir/test-results/UT")

在build.gradle行

firefoxTest {
    systemProperty "webdriver.gecko.driver", "/usr/bin/geckodriver"
}

错误：

我明白，环境有问题，但我不知道我犯了哪些错误？请给我建议，我该如何解决这个问题。谢谢。

Answer 1

一般来说，原因是不同版本的Ubuntu和Firefox免费。如果有人看到这样的错误，我建议从终端执行“apt-cache policy firefox”。现在在Ubuntu 16.04上，您可以看到：

  Installed: 49.0+build4-0ubuntu0.16.04.1
  Candidate: 49.0+build4-0ubuntu0.16.04.1
  Version table:
 *** 49.0+build4-0ubuntu0.16.04.1 500
        500 http://ua.archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages

        100 /var/lib/dpkg/status
     45.0.2+build1-0ubuntu1 500
        500 http://ua.archive.ubuntu.com/ubuntu xenial/main amd64 Packages

在Ubuntu 15.10上：

 Candidate: 47.0+build3-0ubuntu0.15.10.1
 Version table:
    47.0+build3-0ubuntu0.15.10.1 0

    41.0.2+build2-0ubuntu1 0
       500 http://azure.archive.ubuntu.com/ubuntu/ wily/main amd64 Packages

他们必须得到解决。而selenium和其他依赖数据库的回滚版本也无济于事，因为前端可能是浏览器不支持的东西（更不用说FB了），例如：var result = window.Notification.requestPermission(callback)它是https://developer.mozilla.org/ru/docs/Web/API/Notification/requestPermission :)是的，你似乎（查看错误）页面为空是正确的 - 因为ajax无法解决问题。一方面你可能会发现一个错误（不是每个客户都使用最新版本的浏览器），但在我的情况下 - 这是一个加分的痛苦。并且要更新整个系统 - 为粉丝提供娱乐，尽管可能在你的团队中有一个人表现为拖延，在这种情况下，你很幸运。

Answer 2

我收到了错误：

org.openqa.selenium.JavascriptException: Error: Permission denied to access property "navigator"

当我使用Firefox 45.7和gecko驱动程序

时

我将Firefox升级到52.2，错误消失了。
