WebDriver测试用例的问题

Question

I have written a test case using WebDriver, I closed the browser in one method and again I am opening the browser not able to invoke

driver.close(); i closed the browser through above command for again opening a browser i driver.get(url) but i am getting error 'Error communicating with the remote browser It may have died'

Answer 1

Well you killed the browser with your driver.close(); In order to use the driver you must create a new one using something like driver = new FirefoxDriver(capabilities);

Answer 2

If you really want to close the browser before navigating to the new URL, then do:

driver.quit();
driver = new FirefoxDriver();
driver.get(url);

However, why would you want to close the browser before navigating to the new URL in the first place?

I can think of either one of two reasons:

1. You want to go to the next URL with your browser's history cleaned.

   If this is indeed the case, then deleteAllCookies will do the job.

2. You cannot go to the next URL because some popup alert is preventing you doing it.

   If this is indeed the case, then neither close not quit will do the job.

Answer 3

Moving to answer from comment.

I think I got your issue. Though you have called the close() and it only should close the current window, you should use this if you want to shift between multiple windows.

For your case just don't close the driver it will use the same window to open the url.

Answer 4

You have to use following way if you want to close the current browser and open 
a new one:    

webDriver.Close();
//Goto the Target website
WebDriver.Navigate().GoToUrl("url");

And you can use following way if you want to close the browser and kill the
web driver:

webDriver.Close();
webDriver.Quit();
