Question

我正在编写查询SQL Server数据库的黄瓜测试。

下面的查询应该失败，因为表中不存在该记录。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!"); 
}

Answer 1

您在下一行有NullPointerException：

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

并转到异常块，只需在所有异常块中添加以下语句

assertEquals(true, false);

Answer 2

您的while循环未执行，因为结果集中没有记录，并且默认情况下通过了测试用例，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);
}

使用

更改以上代码

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);
}

即使sql查询不返回任何记录，JUnit测试仍在通过
