使用OperaDriver实现Selenium WebDriver

Question

我不能用OperaDriver启动测试。我在这里使用了operadriver-1.5.jar；operadriver-v0.18.zip；operadriver-v1.1.zip和许多其他文件：https://github.com/operasoftware/operadriver/downloads

我使用Selenium Webdriver selenium-server-standalone-2.33.0.jar。

代码示例：

import org.junit.*; 
import org.openqa.selenium.*;
import com.opera.core.systems.OperaDriver;
import com.opera.core.systems.*;

public class Opera_test {
private WebDriver operadriver;
private String baseUrl;

 @Before
 public void setUp() throws Exception {
 operadriver = new OperaDriver();
  baseUrl = "http://www.google.com";
  operadriver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
  }
@Test
public void testCaseGoogle() throws Exception {
  operadriver.get(baseUrl + "/");

 }

 @After
 public void tearDown() throws Exception {
 operadriver.quit();
 }

在那之后我得到了一个错误：

怎么可能修复它呢？

Answer 1

好的，当驱动版本和浏览器不兼容时，我已经看到了这种错误。因此，尝试升级您的Selenium，当前版本是2.35 (我认为您应该保持您的浏览器是最新的，因此这可能会有所帮助)。

Answer 2

下面的java代码应该可以工作。我使用的是Selenium WebDriver 2.53.0

System.setProperty("webdriver.opera.driver", "D:/SeleniumCode_Ripon/operadriver_win64/operadriver.exe");
driver = new OperaDriver();

Answer 3

如果您使用最新版本opera，则应使用operachromiumdriver

如果你想要老版本的opera，那就使用老版本的opera驱动程序。所以这完全取决于你的歌剧版本。
