在写selenium的时候，发现很简单的case也报错
package com.lv.test; import org.junit.Test; import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; public class Orders { private WebDriver driver = new ChromeDriver(); String orderUrl="http://www.baidu.com"; @Test public void OrdersPage(){ driver.get(orderUrl); System.out.println(driver.getTitle()); driver.quit(); }}org.openqa.selenium.WebDriverException: unknown error: Runtime.executionContextCreated has invalid 'context': {"auxData":{"frameId":"15372.1","isDefault":true},"id":1,"name":"","origin":"://"} (Session info: chrome=57.0.2987.110) (Driver info: chromedriver=2.7.236900,platform=Windows NT 6.1 SP1 x86_64) (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 184 milliseconds Build info: version: '2.26.0', revision: '18041', time: '2012-11-01 19:33:38' System info: os.name: 'Windows 7', os.arch: 'amd64', os.version: '6.1', java.version: '1.8.0_20' Driver info: driver.version: RemoteWebDriver Session ID: 0db0541b1e8337218da90c01bd25804b at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at org.openqa.selenium.remote.ErrorHandler.createThrowable(ErrorHandler.java:188) at org.openqa.selenium.remote.ErrorHandler.throwIfResponseFailed(ErrorHandler.java:145) at org.openqa.selenium.remote.RemoteWebDriver.execute(RemoteWebDriver.java:531) at org.openqa.selenium.remote.RemoteWebDriver.get(RemoteWebDriver.java:275) at com.lvmama.test.Orders.OrdersPage(Orders.java:20) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:45) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:42) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:263) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:68) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:47) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:231) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:60) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:229) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:50) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:222) at org.junit.runners.ParentRunner.run(ParentRunner.java:300) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:459) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:675) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:382) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192) 百度后知道这是由于Chrome和chromeDriver的不匹配造成的 然后就查Chrome和chromeDriver的对应关系： 可以在这里http://chromedriver.storage.googleapis.com/index.html，点击其中某个Chrome版本进入到下载页面（我选择的是2.30） 在下载页面有个notes.txt文件，点击这个文件就能看到这个ChromeDriver支持的Chrome版本了
然后下载下来的是一个压缩包，解压其中的.exe文件后，放到Chrome的安装目录下 我的安装目录是：C:\Program Files (x86)\Google\Chrome\Application 如果你是直接复制替换文件，可能会提醒文件被占用的什么东西，可能是刚才你跑selenium的时候没有写diriver.quit() （哎，这坑我都能踩，也是醉了，所以说不管写多简单的case都要最后quit一下，别图省事），只需要打开任务管理器，结束chromedriver.exe就好
