即使 sql 查询应该 return 没有记录,JUnit 测试仍然通过

JUnit test is still passing even though sql query should return no records

我正在编写查询 SQL 服务器数据库的黄瓜测试。

下面的查询应该会失败,因为 table 中不存在该记录。但是,测试通过了。

try { 
        Class.forName(JDBC_DRIVER); 
        System.out.println("Connecting to database..."); 
        conn = DriverManager.getConnection(DB_URL,USER,PASS);  

        System.out.println("Connected database successfully..."); 
        stmt = conn.createStatement(); 
        String sql = "SELECT id FROM tclientlink WHERE id = '0000060115123'"; 
        ResultSet rs = stmt.executeQuery(sql);

        while(rs.next()) { 
            int id  = rs.getInt("goald_client_id"); 
            System.out.print("ID IS HERE: " + id); 
            assertEquals(60115, id);
        } 
        rs.close(); 
    } catch(SQLException se) { 
        se.printStackTrace(); 
    } catch(Exception e) { 
        e.printStackTrace(); 
    } finally { 
        try { 
            if(stmt!=null) stmt.close();  
        } catch(SQLException se2) { 
        }
        try { 
            if(conn!=null) conn.close(); 
        } catch(SQLException se) { 
            se.printStackTrace(); 
        }
    }
    System.out.println("Goodbye!"); 
} 

您在以下行中有 NullPointerException :

int id  = rs.getInt("goald_client_id"); 

然后进入异常块,只需要在所有异常块中添加如下语句

assertEquals(true, false);

您的 while 循环没有执行,因为结果集中没有记录,默认情况下测试用例已通过, 请进行以下更改

while(rs.next()) { 
    int id  = rs.getInt("goald_client_id"); 
    System.out.print("ID IS HERE: " + id); 
    assertEquals(60115, id);
} 

将上面的代码更改为

int noOfRecords = 0;

while(rs.next()) { 
    int id  = rs.getInt("goald_client_id"); 
    System.out.print("ID IS HERE: " + id); 
    assertEquals(60115, id);
    noOfRecords ++;
} 

if( noOfRecords == 0 ) {
    assertEquals(true, false);
}
