我尝试通过模拟数据库查询进行测试,但收到错误:
Asssertion error:AssertionError: Expected call: execute()
Not called
and create_table() not defined.
我想要调用 execute()
并使用 create_table()
返回针对预定义值进行断言的响应。
应用程序.py
from flask import Flask,g
@app.before_request
def before_request():
g.db = mysql.connector.connect(user='root', password='root', database='mysql')
def create_table():
try:
cur = g.db.cursor() #here g is imported form Flask module
cursor.execute ('CREATE TABLE IF NOT EXISTS Man (id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, name VARCHAR(40)')
data = dict(Table='Man is created')
resp = jsonify(data)
cursor.close()
return resp
测试.py
import unittest
from app import *
from mock import patch
class Test(unittest.TestCase):
def test_create(self):
with patch("app.g") as mock_g:
mock_g.db.cursor()
mock_g.execute.assert_called_with()
resp = create_table()
assertEqual(json, '{"Table":"Testmysql is created","Columns": ["id","name","email"]}')
我做错了什么?有人可以告诉我如何解决吗
最佳答案
我相信您需要在关闭光标之前添加更改,否则执行将不会发生。尝试在 cursor.close()
之前(或代替)添加 cursor.commit()
。
