AssertJ断言系列-----------<数据库断言二>

那么，在实际的接口测试中，我们除了要断言响应的数据正确之外，可能有的还需要断言数据层是否数据真的有入库。

assertj db是可以直接对数据库进行断言和操作的。

一、创建一个students表

CREATE TABLE `students` (      `id` VARCHAR(32) DEFAULT NULL,      `Name` VARCHAR(32) DEFAULT NULL,      `Sex` VARCHAR(32) DEFAULT NULL,      `Age` VARCHAR(32) DEFAULT NULL      ) ENGINE=INNODB DEFAULT CHARSET=utf8

二、插入三条数据

insert into `students` (`id`, `Name`, `Sex`, `Age`) values(‘1‘,‘hello‘,‘1‘,‘11‘);insert into `students` (`id`, `Name`, `Sex`, `Age`) values(‘2‘,‘world‘,‘2‘,‘22‘);insert into `students` (`id`, `Name`, `Sex`, `Age`) values(‘3‘,‘java‘,‘3‘,‘33‘);

三、编辑代码

package org.assertj.examples.db;

import org.assertj.db.type.Request;import org.assertj.db.type.Source;import org.junit.BeforeClass;import org.junit.Test;

import java.sql.Connection;import java.sql.DriverManager;import java.sql.SQLException;import java.util.List;import static org.assertj.db.api.Assertions.assertThat;

/** * @ClassName DataAssertionExample * @Description TODO * @Author 12457 * @Date 2019/1/27 10:43 * @Version 1.0 **/

public class DataAssertionExample {

   private static String driver = "com.mysql.jdbc.Driver";   private static String url = "jdbc:mysql://localhost:3306/course";   private static String username = "****"; //实际用户名   private static String password = "****"; //实际密码   private static Connection conn = null;

   /*    *数据库配置连接    **/   @BeforeClass   public static void beforeClass(){      try {         Class.forName(driver);         conn = (Connection) DriverManager.getConnection(url,username,password);      } catch (ClassNotFoundException e) {         e.printStackTrace();      } catch (SQLException e) {         e.printStackTrace();      }

   }

   @Test   public void basic_request_assertion_examples(){      Source source = new Source(url,username,password);      Request request = new Request(source,"SELECT * FROM students");      //获取该表的字段名      List<String> list = request.getColumnsNameList();      for (String s : list) {         System.out.print(s + "\t");      }      //断言name这一列数据      assertThat(request).column("name")      .value().isEqualTo("hello")      .value().isEqualTo("world")      .value().isEqualTo("java");

      //断言数据库表中的数据条数      assertThat(request).hasNumberOfRows(3);

      //断言第一行的数据的值,row(0)代表第一行数据      assertThat(request).row(0)            .value().isEqualTo("1")            .value().isEqualTo("hello")            .value().isEqualTo("1")            .value().isEqualTo("11");   }

   @Test   public void basic_column_request_assertion_examples(){      Source source = new Source(url,username,password);      Request request = new Request(source,"SELECT * FROM students");

      //断言sex列中数据      assertThat(request).column("sex")            .hasValues("1","2","3");   }

   @Test   public void basic_row_request_assertion_examples(){      Source source = new Source(url,username,password);      Request request = new Request(source,"SELECT * FROM students");      assertThat(request).row(1)            .hasValues("2","world","2","22");   }

   @Test   public void size_request_assertion_examples(){      Source source = new Source(url,username,password);      Request request = new Request(source,"SELECT * FROM students");

      //表有4列3行数据      assertThat(request).hasNumberOfColumns(4);      assertThat(request).hasNumberOfRows(3);

      //另外相等的一种写法      assertThat(request).column().hasNumberOfRows(3);      assertThat(request).row().hasNumberOfColumns(4);   }

   @Test   public void request_parameters_examples(){      Source source = new Source(url,username,password);      Request request = new Request(source,"SELECT name,sex FROM students where name like ?","%o%");

      //查询出来有2条数据符号，然后对values值进行判断      assertThat(request).hasNumberOfColumns(2).hasNumberOfRows(2);      assertThat(request)            .row().hasNumberOfColumns(2).hasValues("hello","1")            .row().hasValues("world","2");   }}
