引言

做接口測試的時(shí)候，避免不了操作數(shù)據(jù)庫。因?yàn)閿?shù)據(jù)校驗(yàn)需要，測試數(shù)據(jù)初始化需要、一些參數(shù)化場景需要等。

數(shù)據(jù)庫操作框架設(shè)計(jì)

這里主要操作mysql數(shù)據(jù)庫，整體思路：

封裝實(shí)現(xiàn)

具體代碼實(shí)現(xiàn)：

import pymysqlimport json class OperateMysql(object): def __init__(self): # 數(shù)據(jù)庫初始化連接 self.connect_interface_testing = pymysql.connect( 'localhost', 'root', '123456', 'test', charset=’utf8mb4’, cursorclass=pymysql.cursors.DictCursor ) # 創(chuàng)建游標(biāo)操作數(shù)據(jù)庫 self.cursor_interface_testing = self.connect_interface_testing.cursor() def select_first_data(self, sql): ''' 查詢第一條數(shù)據(jù) ''' try: # 執(zhí)行 sql 語句 self.cursor_interface_testing.execute(sql) except Exception as e: print('執(zhí)行sql異常:%s'%e) else: # 獲取查詢到的第一條數(shù)據(jù) first_data = self.cursor_interface_testing.fetchone() # print(first_data) # 將返回結(jié)果轉(zhuǎn)換成 str 數(shù)據(jù)格式，禁用acsii編碼 first_data = json.dumps(first_data,ensure_ascii=False) # self.connect_interface_testing.close() return first_data def select_all_data(self,sql): ''' 查詢結(jié)果集 ''' try: self.cursor_interface_testing.execute(sql) except Exception as e: print('執(zhí)行sql異常:%s'%e) else: first_data = self.cursor_interface_testing.fetchall() first_data = json.dumps(first_data,ensure_ascii=False) # self.connect_interface_testing.close() return first_data def del_data(self,sql): ''' 刪除數(shù)據(jù) ''' res = {} try: # 執(zhí)行SQL語句 result = self.cursor_interface_testing.execute(sql) # print(result) if result != 0:# 提交修改self.connect_interface_testing.commit()res = {’刪除成功’} else:res = {’沒有要?jiǎng)h除的數(shù)據(jù)’} except: # 發(fā)生錯(cuò)誤時(shí)回滾 self.connect_interface_testing.rollback() res = {’刪除失敗’} return res def update_data(self,sql): ''' 修改數(shù)據(jù) ''' try: self.cursor_interface_testing.execute(sql) self.connect_interface_testing.commit() res = {’更新成功’} except Exception as e: self.connect_interface_testing.rollback() res = {’更新刪除’} return res def insert_data(self,sql,data): ''' 新增數(shù)據(jù) ''' try: self.cursor_interface_testing.execute(sql,data) self.connect_interface_testing.commit() res = {data,’新增成功’} except Exception as e: res = {’新增失敗’,e} return res def conn_close(self): # 關(guān)閉數(shù)據(jù)庫 self.cursor_interface_testing.close() if __name__ == '__main__': # ()類的實(shí)例化 om = OperateMysql() # 新增 data = [{’id’: 1, ’name’: ’測試’, ’age’: 15}, {’id’: 2, ’name’: ’老王’, ’age’: 10}, {’id’: 3, ’name’: ’李四’, ’age’: 20}] for i in data: i_data = (i[’id’],i[’name’],i[’age’]) insert_res = om.insert_data( ''' INSERT INTO test_student (id,name,age) VALUES (%s,%s,%s) ''',i_data ) print(insert_res) # 查詢 one_data = om.select_first_data( ''' SELECT * FROM test_student; ''' ) all_data = om.select_all_data( ''' SELECT * FROM test_student; ''' ) print(one_data) # all_data字符串類型的list轉(zhuǎn)list print('查詢總數(shù)據(jù):%s',len(json.loads(all_data)),'分別是:%s',all_data) # 修改 update_data = om.update_data( ''' UPDATE test_student SET name = ’王五’ WHERE id = 1; ''' ) print(update_data) # 刪除 del_data = om.del_data( ''' DELETE FROM test_student WHERE id in (1,2,3); ''' ) print(del_data) # 關(guān)閉游標(biāo) om.conn_close()

運(yùn)行結(jié)果：

為了方便演示，先注釋刪除數(shù)據(jù)的sql，再執(zhí)行程序：
