使用Selenium的Chrome驱动程序：“找不到适合RemoteWebDriver的构造函数”

我正在尝试在java绑定下使用带有Selenium的chrome驱动程序。 我按照以下说明操作： ChromeDriver说明

所以我运行ChromeDriver.exe，把它放在我的代码WebDriver driver = new RemoteWebDriver("http://localhost:9515", DesiredCapabilities.chrome()); 我收到此错误：

 Error:(33, 28) java: no suitable constructor found for RemoteWebDriver(java.lang.String,org.openqa.selenium.remote.DesiredCapabilities) constructor org.openqa.selenium.remote.RemoteWebDriver.RemoteWebDriver(org.openqa.selenium.remote.CommandExecutor,org.openqa.selenium.Capabilities) is not applicable (argument mismatch; java.lang.String cannot be converted to org.openqa.selenium.remote.CommandExecutor) constructor org.openqa.selenium.remote.RemoteWebDriver.RemoteWebDriver(java.net.URL,org.openqa.selenium.Capabilities) is not applicable (argument mismatch; java.lang.String cannot be converted to java.net.URL) 

如何让Chrome驱动程序工作？

编辑：使用其他方法：

 System.setProperty("webdriver.chrome.driver", "PATH\\chromedriver.exe"); WebDriver driver = new ChromeDriver(); 

我收到这些错误：

 java.lang.NullPointerException at com.example.tests.Scrapjv.testScrapjv(Scrapjv.java:54) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:47) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:44) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:27) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:271) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:70) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) ... ... ... 

Answer 1

我在编写代码时遇到了编译错误The constructor RemoteWebDriver(String, DesiredCapabilities) is undefined

对于Java，你可以试试这样的东西，

  System.setProperty("webdriver.chrome.driver","Drive:"+File.separator+"chromedriver.exe"); driver = new ChromeDriver(); driver.get(url); 

Answer 2

你可以尝试：

 WebDriver driver = new RemoteWebDriver(new java.net.URL("http://localhost:4444/wd/hub"), DesiredCapabilities.chrome());
