今天尝试最新的webDriver与fireFox搭配：
运行代码时出现如下的问题，但是浏览器却可以打开：
org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms at org.openqa.selenium.firefox.internal.NewProfileExtensionConnection.start(NewProfileExtensionConnection.java:96) at org.openqa.selenium.firefox.FirefoxDriver.startClient(FirefoxDriver.java:142) at org.openqa.selenium.remote.RemoteWebDriver.(RemoteWebDriver.java:80) at org.openqa.selenium.firefox.FirefoxDriver.(FirefoxDriver.java:121) at org.openqa.selenium.firefox.FirefoxDriver.(FirefoxDriver.java:77) at com.dci.dids.selenium.SwamiRoleCreationTestCase.setUp(SwamiRoleCreationTestCase.java:20) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.internal.runners.BeforeAndAfterRunner.invokeMethod(BeforeAndAfterRunner.java:74) at org.junit.internal.runners.BeforeAndAfterRunner.runBefores(BeforeAndAfterRunner.java:50) at org.junit.internal.runners.BeforeAndAfterRunner.runProtected(BeforeAndAfterRunner.java:33) at org.junit.internal.runners.TestMethodRunner.runMethod(TestMethodRunner.java:75) at org.junit.internal.runners.TestMethodRunner.run(TestMethodRunner.java:45) at org.junit.internal.runners.TestClassMethodsRunner.invokeTestMethod(TestClassMethodsRunner.java:66) at org.junit.internal.runners.TestClassMethodsRunner.run(TestClassMethodsRunner.java:35) at org.junit.internal.runners.TestClassRunner$1.runUnprotected(TestClassRunner.java:42) at org.junit.internal.runners.BeforeAndAfterRunner.runProtected(BeforeAndAfterRunner.java:34) at org.junit.internal.runners.TestClassRunner.run(TestClassRunner.java:52) 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:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)
org.openqa.selenium.firefox.NotConnectedException 一般这个错误，表示webDriver与fireFox不兼容，webDriver的版本太低，但是我的WebDriver的相关jar的版本是最高的，2.25.0 。
最后发现原来是在eclipse中的webDriver没有更换成最新的jar。
目前经过测试：
webDriver2.25.0 +fireFox36.0
webDriver 2.24+fireFox34.0
可以兼容。
