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

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。
