Question

Selenium是否支持数据库测试？如果是的话，该怎么做？

Answer 1

浏览器测试工具不适合进行数据库测试。为此，您使用常规单元测试框架，因为所有数据库访问都在您的服务器端代码中。

除非您的数据库访问权限基于浏览器，否则您遇到的问题比选择测试框架要大。

Answer 2

如果要连接到数据库，请使用数据库连接API，例如JDBC for Java。

Answer 3

考虑使用TestPlan，它允许您将Web UI测试与自定义Java测试单元结合使用。然后，这些测试单元可以访问您的数据库并在UI脚本中使用它。

Answer 4

For database testing youcan make a connection to the database using JDBC driver and then can fetch data or execute sql queries to perform content testing.

For example-
import java.sql.*;

public class FirstExample {
   // JDBC driver name and database URL
   static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";  
   static final String DB_URL = "jdbc:mysql://localhost/EMP";

   //  Database credentials
   static final String USER = "username";
   static final String PASS = "password";

   public static void main(String[] args) {
   Connection conn = null;
   Statement stmt = null;
   try{
      //STEP 2: Register JDBC driver
      Class.forName("com.mysql.jdbc.Driver");

      //STEP 3: Open a connection
      System.out.println("Connecting to database...");
      conn = DriverManager.getConnection(DB_URL,USER,PASS);

      //STEP 4: Execute a query
      System.out.println("Creating statement...");
      stmt = conn.createStatement();
      String sql;
      sql = "SELECT id, first, last, age FROM Employees";
      ResultSet rs = stmt.executeQuery(sql);

      //STEP 5: Extract data from result set
      while(rs.next()){
         //Retrieve by column name
         int id  = rs.getInt("id");
         int age = rs.getInt("age");
         String first = rs.getString("first");
         String last = rs.getString("last");

         //Display values
         System.out.print("ID: " + id);
         System.out.print(", Age: " + age);
         System.out.print(", First: " + first);
         System.out.println(", Last: " + last);

//Now here you can test wheather the data you have entered through User Interface gets entered into the database
--Write the code for comparision 


      }
      //STEP 6: Clean-up environment
      rs.close();
      stmt.close();
      conn.close();
   }catch(SQLException se){
      //Handle errors for JDBC
      se.printStackTrace();
   }catch(Exception e){
      //Handle errors for Class.forName
      e.printStackTrace();
   }finally{
      //finally block used to close resources
      try{
         if(stmt!=null)
            stmt.close();
      }catch(SQLException se2){
      }
// nothing we can do
      try{
         if(conn!=null)
            conn.close();
      }catch(SQLException se){
         se.printStackTrace();
      }
//end finally try
   }
//end try

}
//end main
}
//end
