使用IE运行Selenium

Question

有人能帮忙吗

 package IEProjects;

    import java.io.File;

    import org.junit.BeforeClass;
    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.chrome.ChromeDriver;
    import org.openqa.selenium.ie.InternetExplorerDriver;
    import org.testng.Assert;
    import org.testng.annotations.AfterClass;
    import org.testng.annotations.Test;

    public class TestIEBrowser {


              static String driverPath = "IE driver path";
              public WebDriver driver;             


                @BeforeClass
                public void setUp() {
                    System.out.println("my IE");
                    System.out.println("launching IE browser");
                    System.setProperty("webdriver.ie.driver","C:\\IEDriverServer_Win32_3.3.0\\IEDriverServer.exe");

                    driver = new InternetExplorerDriver();
                    driver.manage().window().maximize();
                }

                @Test
                public void testGooglePageTitleInIEBrowser() {
                    driver.navigate().to("http://www.google.com");
                    String strPageTitle = driver.getTitle();
                    System.out.println("Page title: - "+strPageTitle);
                    Assert.assertTrue(strPageTitle.equalsIgnoreCase("Google"), "Page title doesn't match");
                }

                @AfterClass
                public void tearDown() {
                    if(driver!=null) {
                        System.out.println("Closing IE browser");
                        driver.quit();
        }

    }
    }

下面是错误，谢谢你的及时回复。

根本原因是驱动程序没有正确初始化。

我认为您不正确地从Junit而不是testNG导入beforeClass注释，从而导致setUp方法未被调用，结果驱动程序未被初始化

请将import更改为import org.testng.annotations.BeforeClass；
