selenium - WebDriver异常: Error: Permission denied to access property "navigator"

Question

下面是遇到的“魔法”的处理:代码在 Ubuntu 16.04 上运行良好，在 Ubuntu 15.10 上运行有错误:

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:

LoginSpec > #0 go to login FB FAILED

我明白，环境有问题，但我不知道我哪里出错了？请给我建议，我该如何解决这个问题。谢谢。

总的来说，原因是 Ubuntu 和 Firefox 的版本不同。如果看到有人出现这样的错误，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

     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

这些问题必须得到解决。而回滚版本的selenium等依赖数据库也无能为力，因为在前端可能会有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，你是对的，似乎(查看错误)该页面是空的 - 对于 ajax不成功。一方面，您可能会发现一个错误(并非每个客户都使用最新版本的浏览器)，但就我而言 - 这是一个额外的痛苦。并更新整个系统 - 为粉丝提供娱乐，尽管您的团队中可能有一个人表现出拖延症，在这种情况下，您很幸运。
