[笨方法学python]习题51自动化测试笔记

习题51

本节自动化测试部分看不大懂，自己每步都打印出来，帮助理解。( 代码标红部分为自己加入调试为打印变量值所用 ）

tests/tools.py

from nose.tools import *

import re

def pt(resp,contains=None,matches=None,headers=None,status=None):

print 'resp:'.resp

print ' resp.data:',resp.data #个人加入调试，为打印出每次调用变量值

print 'contains:',contains

print 'matches:',matches

print 'headers:',headers

print 'status:',status

print '******************************************************************'

def assert_response(resp, contains=None, matches=None, headers=None, status="200"):

assert status in resp.status, "Expected response %r not in %r" % (status, resp.status)

if status == "200":

assert resp.data, "Response data is empty."

if contains:

assert contains in resp.data, "Response does not contain %r" % contains

if matches:

reg = re.compile(matches)

assert reg.matches(resp.data), "Response does not match %r" % matches

if headers:

assert_equal(resp.headers, headers)

tests/app_tests.py

from nose.tools import *

from bin.app import app

from tests.tools import assert_response

from tests.tools import pt                                              #个人加入调试，为打印出每次调用变量值

def test_index():

# check that we get a 404 on the / URL

resp = app.request("/")

assert_response(resp, status="404")

pt(resp) #个人加入调试，为打印出每次调用变量值

# test our first GET request to /hello

resp = app.request("/hello")

assert_response(resp)

pt(resp) #个人加入调试，为打印出每次调用变量值

# make sure default values work for the form

resp = app.request("/hello", method="POST")

assert_response(resp, contains="Nobody")

pt(resp) #个人加入调试，为打印出每次调用变量值

# test that we get expected values

data = {'name': 'Zed', 'greet': 'Hola'}

resp = app.request("/hello", method="POST", data=data)

assert_response(resp, contains="Zed")

pt(resp) #个人加入调试，为打印出每次调用变量值

test_index() #个人加入调试，为打印出每次调用变量值

我将每一次调用assert_response()，各个变量的值打印出来：（**********表示第一次调用结束）

resp: <Storage {'status': '404 Not Found', 'headers': {'Content-Type': 'text/html'}, 'header_items': [('Content-Type', 'text/html')], 'data': 'not found'}>

resp.data: not found

matches: None

headers: None

assert断言语句

assert  1==2，‘不等于！’

若表达式为真则无回显，若不为真，则抛出异常。

app.request("/")：为发送一个url请求后，值为服务器返回的响应。
