Java Selenium：错误：无法访问 MutableCapabilities

Question

尝试将我们的代码更新到 Selenium 3.x，但在尝试运行我们的测试时不断遇到错误：

error: cannot access MutableCapabilities

就运行测试而言，同样的代码过去一直有效，但我不确定它在哪里或为什么会出现如此奇怪的错误。我似乎找不到任何人以前写过的东西，所以我希望 stackoverflow 社区可以帮助我。

这是产生此错误的代码：

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，原来我的问题是因为 maven 中的一些依赖项让我全都缠绕在轴上。我发帖希望如果其他人遇到这个问题，他们可以查看这里并弄清楚发生了什么。

所以对我来说，以下工件不在正确、匹配的 selenium 版本上：

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

一旦我将这些更正为我正在运行的相同版本的 selenium (3.5.3)，我就能够成功打开 Firefox，而没有出现我之前遇到的异常。

我一直有这个问题， 我的解决方案是添加/更新 pom.xml
