Java Selenium:错误:无法访问MutableCapabilities

Question

试图将我们的代码更新到Selenium 3.x，当我试图运行我们的测试时，我总是遇到一个抛出的错误：

error: cannot access MutableCapabilities

同样的代码过去在运行测试时也是有效的，我真的不确定它会在哪里或者为什么会出现这样一个奇怪的错误。我似乎找不到任何人之前写过的东西，所以我希望stackoverflow社区能帮助我解决这个问题。

以下是生成此错误的代码：

package com.iacapps.ste.ta.helpers;

import com.google.common.base.Strings;
import com.paypal.selion.platform.grid.browsercapabilities.DefaultCapabilitiesBuilder;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.util.Collections;

public class CustomCapabilities extends DefaultCapabilitiesBuilder
{
  private static final Logger logger = LoggerFactory.getLogger(DefaultCapabilitiesBuilder.class);

  private static final String SAUCE_TUNNEL_PROPERTY = "sauceTunnel";
  private static final String SAUCE_ENABLED_PROPERTY = "enableSauceConnect";
  private static final String TUNNEL_CAPABILITY = "tunnelIdentifier";
  private static final String ACCEPT_ALL_SSL_CAPABILITY = "acceptSslCerts";
  private static final String CHROME_SWITCHES = "chrome.switches";
  private static final String CHROME_IGNORE_SSL = "--ignore-certificate-errors";
  private static final String FIREFOX_ACCEPT_BAD_CERTS_CAPABILITY = "acceptInsecureCerts";

  @Override
  public DesiredCapabilities getCapabilities(DesiredCapabilities capabilities)
  {
    String sauceEnabledValue = System.getProperty(SAUCE_ENABLED_PROPERTY);
    String tunnelIdValue = System.getProperty(SAUCE_TUNNEL_PROPERTY);
    //This will just prevent the warning being printed when sauceconnect isn't enabled.
    if (!Strings.isNullOrEmpty(sauceEnabledValue) && Boolean.valueOf(sauceEnabledValue))
    {
      if (Strings.isNullOrEmpty(tunnelIdValue))
      {
        logger.warn("{} not set", SAUCE_TUNNEL_PROPERTY);
      }
      else
      {
        capabilities.setCapability(TUNNEL_CAPABILITY, tunnelIdValue);
      }
    }
    //There's a reason for this charlie foxtrot.  I don't always get to know what browser driver I'm
    //talking to.
    //Per selenium docs: "Whether the session should accept all SSL certs by default."
    //The DOWNSIDE: this seems to work with newer browser drivers, but it may not work with old ones.
    capabilities.setCapability(ACCEPT_ALL_SSL_CAPABILITY, true);
    //This *supposedly* works with some versions of IE.
    capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
    //This *supposedly* works with some chrome versions.

    capabilities.setCapability(CHROME_SWITCHES, Collections.singletonList(CHROME_IGNORE_SSL));
    //Oh my god please work you STUPID FIREFOX
    //http://stackoverflow.com/a/40788935
    //https://bugzilla.mozilla.org/show_bug.cgi?id=1103196
    //Should work with firefox > v51
    capabilities.setCapability(FIREFOX_ACCEPT_BAD_CERTS_CAPABILITY,true);
    //When in doubt SET EVERYTHING!
    FirefoxProfile profile = new FirefoxProfile();
    profile.setAcceptUntrustedCertificates(true);
    profile.setAssumeUntrustedCertificateIssuer(false);
    capabilities.setCapability(FirefoxDriver.PROFILE,profile);
    capabilities.setCapability(FirefoxDriver.MARIONETTE,false);
    return capabilities;
  }
}

Answer 1

好吧，事实证明，我的问题是因为maven中的一些依赖项让我完全被轴缠住了。我发帖是希望如果其他人遇到这个问题，他们可以看看这里，弄清楚是怎么回事。

因此，对我来说，以下工件不是在正确的、匹配的selenium版本上：

• selenium-support
• selenium-java
• selenium-api

一旦我将它们更正为与我正在运行的selenium版本(3.5.3)相同的版本，我就能够成功地打开firefox，而不会出现之前得到的异常。

我一直有这个问题，我的解决方案是添加/更新pom.xml
