NoSuchSessionException當啓動chromedriver

我想創建一個簡單的測試，只需打開頁面並驗證其標題。我認爲它不能再簡單，但是...我的測試中打開在當前打開Chrome瀏覽器的新選項卡上卻失敗driver.get(myUrl);與org.openqa.selenium.NoSuchSessionExceptionNoSuchSessionException當啓動chromedriver

我試圖升級和降級chromedriver和升級降級硒，但沒有運氣遠。目前我在selenium-java 3.3.1，chromedriver 2.28和chrome 57.0.2987.98上。任何幫助讚賞。

獎金問題，上次我用chromedriver打開了一個新的瀏覽器窗口，有什麼辦法可以回到那個上？我更喜歡我的測試在新窗口而不是新標籤。

public class MyExampleTest { 
    private String baseUrl; 
    private WebDriver driver; 

    @Before 
    public void openBrowser() { 
     baseUrl = "http://myurl/"; 
     System.setProperty("webdriver.chrome.driver", "C:\\Projects\\chromedriver.exe"); 
     driver = new ChromeDriver(); 
     driver.get(baseUrl); 
    } 

    @Test 
    public void pageTitleAfterSearchShouldBeThere() throws IOException { 
     assertEquals("The page title should be this at the start of the test.", "my title", driver.getTitle()); 
    } 
}

堆棧跟蹤：

在這裏發佈您的完整代碼。 – kushal

你能不能也粘貼堆棧跟蹤？ – Mikhail

你可能已經搞砸了imports。試試下面的代碼，對我來說工作得很好。

import static org.junit.Assert.assertEquals; 

import java.io.IOException; 

import org.junit.After; 
import org.junit.Before; 
import org.junit.Test; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.chrome.ChromeDriver; 

public class MyExampleTest { 
    private String baseUrl; 
    private WebDriver driver; 

    @Before 
    public void openBrowser() { 
     baseUrl = "http://facebook.com/"; 
     System.setProperty("webdriver.chrome.driver", System.getProperty("user.dir")+"\\chromedriver.exe"); 
     driver = new ChromeDriver(); 
     driver.get(baseUrl); 
     driver.manage().window().maximize(); 
    } 

    @Test 
    public void pageTitleAfterSearchShouldBeThere() throws IOException { 
     System.out.println(driver.getTitle()); 
     assertEquals("The page title should be this at the start of the test.", "Facebook - Log In or Sign Up", driver.getTitle()); 
    } 

    @After 
    public void closeBrowser(){ 
     try{ 
     driver.quit(); 
     }catch(Exception e){ 
      System.out.println(e.getMessage()); 
     } 
    } 
}

這將打開一個new window每次不是已經打開的瀏覽器中的新標籤。

你在同一個版本的硒/鉻/鉻金屬？對我來說，你的代碼會拋出NoSuchSession異常，也會打開一個新的標籤，而不是一個新的瀏覽器窗口。和我上面一樣。 – tom

是的我已經在你提到的問題中試過這個版本。 –
