在使用Java在Selenium网络驱动程序中运行我的一个测试用例时，我面临着“无法实例化类”错误。
下面是测试功能的类别
public class LoginPageTest extends TestBase{
LoginPage loginPage;
HomePage homepage;
public LoginPageTest(){
super();
}
@BeforeMethod
public void setUp(){
initialization();
loginPage = new LoginPage();
}
@Test(priority=1)
public void loginPageTitleTest(){
String title = loginPage.validateLoginPageTitle();
Assert.assertEquals(title,"#1 Free CRM software in the cloud for sales and service");
}
@Test(priority=2)
public void crmLogoImageTest(){
boolean flag = loginPage.validateCRMImage();
Assert.assertTrue(flag,"Image not found");
}
@Test(priority=3)
public void loginTest(){
homepage = loginPage.login(prop.getProperty("username"), prop.getProperty("password"));
}
@AfterMethod
public void tearDown(){
driver.quit();
}
}
