Question

我正在尝试使用带有Java的Automation Selenium WebDriver将MySQL数据库中的值传递给UI？代码只返回第一行。

以下是数据库值：

我已经多次使用int循环更改了代码，并收到了不同类型的错误，例如：

在结果集开始之前
结果集结束后

我无法弄明白。我不确定我做错了什么。

基本上，在这种情况下，我有firstName和lastName通过数据库传递给UI。我想将这些值传递给我的测试用例。我不想硬编码。目前，我有一个包含2列的表，一列是firstName，第二列是lastName。

我希望遍历数据库并在任何我想要的地方选择这些值。的SendKeys。

这是我的测试用例代码文件。

下面的FacebookTest文件代码。

import static org.testng.Assert.assertThrows;
import java.sql.Array;
import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.Test;
import selenium.ReadExcel;


public class FacebookTest 
{
    @SuppressWarnings({ "static-access", "unchecked" }) 
    public static void main(String[] args) throws Exception 
    //public static void facebookTest()
    {       
        // pointing to the file, now FF must have pointer as well in Selenium 3.0
        // WebDriver

        System.setProperty("webdriver.gecko.driver","geckodriver.exe");
        // OPEN FF
        FirefoxDriver driver = new FirefoxDriver();

        DBTestData db = new DBTestData();


        // ENTER URL
        driver.get("http://www.facebook.com/");             

        try
        {   
            ResultSet testData = db.data("","");

            for(int i = 0; i < 10; i++) 
            {               
                String firstName = testData.getString("firstName");
                String lastName = testData.getString("lastName");           

                System.out.println(firstName);
                System.out.println(lastName);
                driver.findElement(By.id("u_0_e")).clear();
                driver.findElement(By.id("u_0_e")).sendKeys(firstName);
                driver.findElement(By.id("u_0_g")).clear();
                driver.findElement(By.id("u_0_g")).sendKeys(lastName);
            }
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
        finally
        {           
            driver.quit();          
        }
    }
}

这是我的数据库文件，我从数据库中获取值并将其返回到测试用例101 - 请参阅下面的代码。

下面的DBTestData代码文件。

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.util.ArrayList;

public class DBTestData {
    // public static void main(String[] args) throws Exception
    @SuppressWarnings({ "unused" })
    // public static String data() throws Exception

    public static ResultSet data(String firstName, String lastName) throws ClassNotFoundException, SQLException 
    {       
            // Accessing driver from the JAR file
            Class.forName("com.mysql.jdbc.Driver");

            // Creating a variable for the connection called "con"
            Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "username", "password");
            // after localhost:3306 is where you will put the name of the database
            // jdbc:mysql://localhost:3606/testdb ---> this is a database
            // root is a database user and password too

            // our query below
            PreparedStatement statement = con.prepareStatement("SELECT firstName, lastName FROM test_data");

            // creating variable to execute query
            ResultSet result = statement.executeQuery();

            // List sqlData = new ArrayList();
            ArrayList<String> sqlData = new ArrayList<String>();

                while (result.next()) 
                {               
                    sqlData.add(firstName = result.getString(firstName));
                    sqlData.add(lastName = result.getString(lastName));

                }
                    return result;              
    }
}

让我知道如何实现这一概念。一旦我掌握了基础知识，我将使用相同的文件来测试其他测试用例。为什么我们不能使用相同的概念2D数组将值从数据库传递到UI？

Answer 1

以下是我解决问题的方法。我在我的测试用例中使用了do while循环，它能够从所有行获取所有数据并在我的网页中迭代它。

以下是代码。

FacebookTest代码文件：

import static org.testng.Assert.assertThrows;
import java.sql.Array;
import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.Test;
import selenium.ReadExcel;


public class FacebookTest 
{
 @SuppressWarnings({ "static-access", "unchecked" }) 
 public static void main(String[] args) throws Exception 
 { 
 // pointing to the file, now FF must have pointer as well in Selenium 3.0 WebDriver
 System.setProperty("webdriver.gecko.driver","geckodriver.exe");

 // OPEN FF
 FirefoxDriver driver = new FirefoxDriver();

 DBTestData db = new DBTestData(); 

 // ENTER URL
 driver.get("http://www.facebook.com/");

 try
 {

 ResultSet testData = db.data("","");

 do 
 {
   String firstName = testData.getString(1);
   String lastName = testData.getString(2);

   driver.findElement(By.id("u_0_e")).clear();
   driver.findElement(By.id("u_0_e")).sendKeys(firstName);
   driver.findElement(By.id("u_0_g")).clear();
   driver.findElement(By.id("u_0_g")).sendKeys(lastName); 

 }
 while(testData.next()); 



 }
 catch (Exception e)
 {
 e.printStackTrace();
 }
 finally 
 { 
 driver.quit(); 
 }
 }
}

这是我的DBTestData文件：

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.util.ArrayList;


public class DBTestData 
{
 public static ResultSet data(String firstName, String lastName) throws ClassNotFoundException, SQLException 
 { 

 // Accessing driver from the JAR file
 Class.forName("com.mysql.jdbc.Driver"); 

 // Creating a variable for the connection called "con"
 Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "username", "password");

 // after localhost:3306 is where you will put the name of the database
 // jdbc:mysql://localhost:3606/testdb ---> this is a database
 // root is a database user and password too

 // our query below
 PreparedStatement statement = con.prepareStatement("SELECT firstName, lastName FROM test_data");

 // creating variable to execute query
 ResultSet result = statement.executeQuery(); 

 // store all the rows data into one variable
 ArrayList<String> sqlData = new ArrayList<String>(); 

 while(result.next())
 {
   sqlData.add(firstName= result.getString("firstName"));
   sqlData.add(lastName = result.getString("lastName")); 
   break;
 } 
 return result;
 } 
}

那么，如何正确关闭数据库连接？

如何迭代n行？

由于

Answer 2

con.close();是关闭数据库的命令

使用Automation Selenium WebDriver with Java将值从数据库传递到UI？
