selenium使用中遇到的问题

1、Exception in thread "main" org.openqa.selenium.WebDriverException: Cannot find firefox binary in PATH. Make sure firefox is installed. OS appears to be: XP
Build info: version: '2.16.1', revision: '15405', time: '2012-01-05 12:30:12'
解决办法：

我们只要在WebDriver driver = new FirefoxDriver(); 前面指定我们浏览器的具体信息即可：

System.setProperty ( "webdriver.firefox.bin" , "E:/Program Files/Mozilla Firefox/firefox.exe" );

WebDriver driver = new FirefoxDriver();

2、Exception in thread "main" Java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, seehttp://code.google.com/p/selenium/wiki/ChromeDriver. The latest version can be downloaded fromhttp://code.google.com/p/chromedriver/downloads/list
 at com.google.common.base.Preconditions.checkState(Preconditions.java:176)
 at org.openqa.selenium.remote.service.DriverService.findExecutable(DriverService.java:105)
 at org.openqa.selenium.chrome.ChromeDriverService.createDefaultService(ChromeDriverService.java:75)
 at org.openqa.selenium.chrome.ChromeDriver.<init>(ChromeDriver.java:107)
 at com.example.tests.Selenium2ForChrome.main(Selenium2ForChrome.java:18)
出现这个错误的原因是因为谷歌浏览器和selenium不是原生的，需要在谷哥里面装插件，插件下载地址是http://code.google.com/p/chromedriver/downloads/list。

暂时还没解决好。

3、The path to the driver executable must be set by the webdriver.ie.driver system property; for more information, see http://code.google.com/p/selenium/wiki/InternetExplorerDriver. The latest version can be downloaded from http://code.google.com/p/selenium/downloads/list 

该问题的错误原因和上面的一样，用IEdriver的时候也需要装插件，去http://code.google.com/p/selenium/downloads/list 下载对应的插件版本，然后修改代码如下：

[java] view plain copy
File file = new File("C:/Selenium/iexploredriver.exe");
System.setProperty("webdriver.ie.driver", file.getAbsolutePath());
WebDriver driver = new InternetExplorerDriver();

4、Exception in thread "main" org.openqa.selenium.remote.SessionNotFoundException: Unexpected error launching Internet Explorer. Browser zoom level was set to 119%. It should be set to 100% (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 5.98 seconds

错误原因：IE浏览器的比例调大了，按ctrl+0，可以恢复原来的大小，即可。PS：这种错误真是。。。让人无语。

5、My97DatePicker控件输入日期问题

之前用的是seleniumIDE自己录制的代码，结果回放的时候总是说元素找不到，整的我很头疼，后来发现一个简单的办法，就是直接把值输入日期控件的输入框当中来，

[java] view plain copy
driver.findElement(By.id("bookDay")).clear();
        driver.findElement(By.id("bookDay")).sendKeys("2013-06-17");  

不过我觉得这个方法不好，还在寻找其他办法。
在网上找了下，有下面这个方法，问题是我看不懂。。。

[java] view plain copy
selenium.selectFrame("relative=up");
  //点击日期文本框
  selenium.click("days");
  //必须增加Thread.sleep()，不增加会报错，提示找不到下一条命令中的元素
  //另，尝试使用waitForPageToLoad代替，会超时出错；
  Thread.sleep(5000);
  //当前为4月，向前移两个月
  selenium.click("//div[@id='dpTitle']/div[2]");
  selenium.click("//div[@id='dpTitle']/div[2]");
  //点击2009-02-02
  selenium.click("//td[@onclick='day_Click(2009,2,2);']");
