使用mock对conn()进行单元测试:

app.py

import mysql.connector
import os,urlparse

def conn():
  if 'DATABASE_URL' in os.environ:
     url=urlparse(os.environ['DATABASE_URL'])
     g.db = mysql.connector.connect(user=url.username,password=url.password, host=url.hostname,database=url.path[1:])
  else mysql.connector.error.Errors as err:
     return "Error

test.py

def test_conn(self):
 with patch(app.mysql.connector) as mock_mysql:
   with patch(app.os.environ) as mock_environ
   con()
   mock_mysql.connect.assert_callled_with("credentials")

错误:未调用断言 mock_mysql.connect.assert_called_with.

我认为这是因为'Database_url'不在我修补的os.environ中,因为没有对mysql_mock.connect进行测试调用.

问题:

1我需要做些什么改变才能使这个测试代码工作？

我还要修补'urlparse'吗？

考虑这个正则表达式.

a*b

这将失败的情况下 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaac

这会使67调试器中的步骤失败.

现在考虑这个正则表达式.

(?>a*)b

这将失败的情况下 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaac

这会使133调试器中的步骤失败.

最后这个正则表达式:

a*+b  (a variant of atomic group)

这将失败的情况下 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaac

这会使67调试器中的步骤失败.

当我检查基准测试atomic group (?>a*)b执行179%得更快.

现在原子组禁用回溯.所以比赛中的表现很好.

1. 但为什么步数更多呢？有人可以解释一下吗？

2. 为什么会有差异.在两个原子团(?>a*)b和之间的步骤a*+b.

他们的工作方式不同吗

我发送的配置单元查询是:

有没有人知道如何通过appium python客户端缩放android中的元素？

我目前正在使用

self.driver.zoom(self.element, percent) 但这会给出错误

self.driver.zoom(self.element, percent)
File "/usr/local/lib/python2.7/site-packages/appium/webdriver/webdriver.py", line 308, in zoom
self.execute_script('mobile: pinchOpen', opts)

我也试过了MultiAction.

loc = self.element.location
print loc
xx, yy = loc["x"], loc["y"]
xx=700
action1 = TouchAction(self.driver)
action1.long_press(x=xx, y=yy).move_to(x=0, y=1000).release()
action2 = TouchAction(self.driver)
action2.long_press(x=xx, y=yy).move_to(x=0, y=-1000).release()
m_action = MultiAction(self.driver)
m_action.add(action1, action2) …

我正在创建一个dataframe来自csv.我已经通过文档,多个SO帖子,链接,因为我刚刚开始Pandas但没有得到它.csv有多个具有相同名称的列说a.

所以在形成之后dataframe,当我做df['a']哪个值时它会返回？它不会返回所有值.

也只有一个值会有一个字符串休息.None我怎么能得到那个列？

当我们这样做时table.batch_writer(),boto3 API,它是插入还是更新？

通过更新我的意思是partition key,sort key are same但其他attributes不一样.我在任何文档中都找不到这个.

所以我有一个图像让我们说small.png和一个更大的图像big.png.小图像在较大的图像中出现2次,我希望找到它的位置.

我尝试使用numpy和Image但是出错了

'JpegImageFile' object has no attribute '__getitem__'我之前有png格式,它给出了同样的错误.

是否有任何其他模块或方法来完成这一点.我对任何人开放.

现在抛出错误的代码是

import numpy
from PIL import Image
here = Image.open(r"/Users/vks/Desktop/heren.jpg")
big = Image.open(r"/Users/vks/Desktop/Settingsn.jpg")
print here,big
herear = numpy.asarray(here)
bigar = numpy.asarray(big)
herearx = herear.shape[0]
hereary = herear.shape[1]

bigarx = bigar.shape[0]
bigary = bigar.shape[1]

print herearx , hereary , bigarx, bigary

stopx = bigarx - herearx + 1
stopy = bigary - hereary + 1

for x in range(0, stopx):
    for y in range(0, stopy): …

使用Eclipse Mars.我已经通过安装软件从help.Iow添加了aws java sdk 1.11.123.当我运行Tomcat Server 7时,我收到此错误:

May 02, 2017 11:57:32 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet [PdsServlet] in context with path [/PdsAWS] threw exception [java.lang.NoClassDefFoundError: Could not initialize class com.amazonaws.partitions.PartitionsLoader] with root cause java.lang.NoClassDefFoundError: Could not initialize class com.amazonaws.partitions.PartitionsLoader

我也明白了

java.lang.NoSuchFieldError: ALLOW_FINAL_FIELDS_AS_MUTATORS

但是,当我检查库时,我可以看到PartitionsLoader.How可以解决这个问题吗？
