我得到“无法实例化class packageName.pageName”将尝试在selenium中执行测试用例。我尝试了很多，但没有找到我犯这个错误的地方。无法实例化类packageName.pageName
下面是我的登录页面
package detailsPkg_user;
public class Login {
public static WebDriver driver;
String username = "userName";
String password = "passWord";
String baseurl = "http://mybusiness.com/login.aspx";
WebDriverWait wait = new WebDriverWait(driver, 10); // 10 seconds
public class Details {
@Test(priority = 0)
public void loginpage() {
System.setProperty("webdriver.chrome.driver","D:\\From H\\Selenium Package\\ChromeDriver\\chromedriver_win32\\chromedriver.exe");
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability("chrome.switches", Arrays.asList("--incognito"));
ChromeOptions options = new ChromeOptions();
options.addArguments("--test-type");
options.addArguments("--disable-extensions");
capabilities.setCapability("chrome.binary","D:\\From H\\Selenium Package\\ChromeDriver\\chromedriver_win32\\chromedriver.exe");
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
driver = new ChromeDriver(capabilities);
driver.manage().deleteAllCookies();
driver.manage().window().maximize();
driver.get(baseurl);
WebElement username = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("UserName")));
username.sendKeys(userName);
WebElement password = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("PassWord")));
password.sendKeys(passWord);
WebElement button = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("ButtonClick")));
button.click();
}
// Selecting a date from date picker
@Test(priority = 1)
public void RecordSearch() {
WebElement calendar = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("CalendarId")));
calendar.click();
WebElement month = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("XPath")));
month.click();
WebElement day = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("XPath")));
day.click();
WebElement submit = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("Submit")));
submit.click();
}
driver.close();
}
而且下面是detailSearch页面代码
package detailsPkg_user;
import org.testng.annotations.Test;
import java.util.Arrays;
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.JavascriptExecutor;
public class detailSearch extends Login {
@Test(priority = 2)
public void loginpageDetail() {
System.setProperty("webdriver.chrome.driver","D:\\From H\\Selenium Package\\ChromeDriver\\chromedriver_win32\\chromedriver.exe");
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability("chrome.switches", Arrays.asList("--incognito"));
ChromeOptions options = new ChromeOptions();
options.addArguments("--test-type");
options.addArguments("--disable-extensions");
capabilities.setCapability("chrome.binary","D:\\From H\\Selenium Package\\ChromeDriver\\chromedriver_win32\\chromedriver.exe");
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
driver = new ChromeDriver(capabilities);
driver.manage().deleteAllCookies();
driver.manage().window().maximize();
driver.get(baseurl);
WebElement username = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("UserName")));
username.sendKeys(userName);
WebElement password = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("Password")));
password.sendKeys(passWord);
WebElement button = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("ButtonClick")));
button.click();
}
// Selecting and clicking DetailSearch menu
@Test(priority = 3)
public void detailSelect() {
WebElement detailMenu = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("XPath")));
detailMenu.click();
// Datepicker of "From" calendar
WebElement datepickerFrom = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("calendarId01")));
datepickerFrom.click();
WebElement monthPreviousFrom = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("leftarrow_calendar_NP']/img")));
monthPreviousFrom.click();
WebElement dayFirst = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("XPath")));
dayFirst.click();
// Datepicker of "To" calendar
WebElement datepickerTo = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("calendarId02")));
datepickerTo.click();
WebElement monthPreviousTo = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("leftarrow_calendar_NP']/img")));
monthPreviousTo.click();
WebElement monthLast = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("XPath")));
monthLast.click();
}
// Click "Submit"
WebElement submit = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("ctl00_contentMiddle_btnSearch")));
submit.click();
WebElement logout = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("XPath")));
logout.click();
driver.close();
}
}
当我试图执行该项目。我在控制台中收到以下错误。

“Login.java”的第25行是什么？ –
@ chiastic-security ...这是一个空白的行。 “WebDriverWait等待=新的WebDriverWait（驱动程序，10）”; // 10秒“ – Arvind
”这是否意味着缺少一些代码，因为它看起来不像第25行？ – Josh
