selenium 启动chromedriver时出现NoSuchSessionException异常

我正在尝试创建一个简单的测试，只需打开页面并验证其标题。我认为这不能再简单了，但是...我的测试在当前打开的Chrome浏览器中打开了一个新标签，并且在driver.get(myUrl);上失败，因为org.openqa.selenium.NoSuchSessionException
我试过升级和降级chromedriver和升级降级selenium，但到目前为止没有成功。目前我正在使用selenium-java 3.3.1，chromedriver 2.28和chrome 57.0.2987.98。任何帮助都很感谢。
额外的问题，上次我使用chromedriver它打开了一个新的浏览器窗口，有什么办法回到那个吗？我更喜欢我的测试在一个新的窗口，而不是一个新的标签。

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());
    }
}

堆栈跟踪：

这是因为不匹配的chromedriver版本和兼容的webdriver版本。要么改变它的任何一个或采取两个最新的。这对我工作！

您需要检查chrome驱动程序下载页面https://chromedriver.chromium.org/downloads
上面写着兼容性......另外，看看这里有一个兼容的驱动程序n浏览器https://stackoverflow.com/a/55266105/6305768的列表

你可能搞砸了imports。试试下面的代码，对我来说很好。

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());
        }
    }
}

这将打开一个new window每次不是一个新的标签在已经打开的chrome浏览器。
