Question

我正在运行以下代码并收到错误消息“无法解析搜索框。我该如何解决此问题？请帮助。我无法找出收到此错误的原因。提前致谢:)

import java.io.File;
import java.io.FileInputStream;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class DataDriven_Ex {

     public static void main(String[] args) { 

    FirefoxDriver driver = new FirefoxDriver();
     driver.get("http://www.amazon.in");

    WebElement searchbox = driver.findElement(By.xpath("//*[@id='twotabsearchtextbox']"));
     }

     @Test
    public void test() throws Exception {

        File file = new File("F://Selenium excel//DataDriven.xlsx");
        FileInputStream fs = new FileInputStream(file);
        XSSFWorkbook wb = new XSSFWorkbook(fs);
        XSSFSheet sh = wb.getSheet("Sheet1");


        int rowcount = sh.getLastRowNum();

        for (int i = 0; i<=rowcount;i++)
        {

            String keyword = sh.getRow(i).getCell(0).getStringCellValue();


            searchbox.sendKeys(keyword);

            searchbox.submit();      

        }

    }       

    }

Answer 1

您的搜索框变量在本地声明到静态方法main()。搜索框在 test() 方法中不可见。这是代码中的问题。

解决方案:将搜索框声明从方法移动到类。并在变量声明中添加 static 修饰符。请参阅下面的代码。

static WebElement searchbox;

public static void main(String[] args)
{ 

    FirefoxDriver driver = new FirefoxDriver();
    driver.get("http://www.amazon.in");

    searchbox = driver.findElement(By.xpath("//*[@id='twotabsearchtextbox']"));
}
