单元测试十：自动化测试示例一

一、编写测试用例

在python中string库的Template类可以将字符串的格式固定下来，重复利用。 同一套测试框架为了可以复用，所以我们可以将用例部分做参数化，然后运用到各个项目中。

1.态生成单个测试用例函数字符串:

from string import Template
"""
功能：自动生成pyunit框架下的接口测试用例
环境：python2.7.6
用法：将用户给的参数处理成对应格式,然后调用模块类生成函数，并将参数传入即可
"""
# 动态生成单个测试用例函数字符串
def singleMethodCreate(MethodList, interfaceNamePara):
    code = Template('''\n    def test_${testcase}(self):
        u"""${testcaseName}"""
        headers = $headers
        data = $data
        re = requests.$method(url='$url',headers=headers,data=data)
        status_code = re.status_code
        s = str(status_code)
        json = re.text
        logging.info('-'*5+'返回状态码是'+s+'-'*5)
        logging.info('-'*5+'返回结果集是'+json+'-'*5)
        assert status_code == 200
        assert json['status'] == 'ok'
''')

    string = code.substitute(testcase=MethodList["testcase"],
                             testcaseName=MethodList["TestcaseName"],
                             method=MethodList['method'],
                             url=MethodList['url'],
                             headers=MethodList['headers'],
                             data=MethodList['data'],
                             )
    return string

method_list = {
    "testcase": "a1",
    "TestcaseName": "a2",
    "method": "a3",
    "url": "a4",
    "headers": "a5",
    "data": "a6"
}
print(singleMethodCreate(method_list, "abc"))

 

2.拼接单个的测试用例函数字符串为完整字符串并传回主函数:

#MethodParaList获取测试用例部分list
def methodCreate(MethodParaList,interfaceNamePara):
    string = ""
    for MethodPara in MethodParaList:
        string2=singleMethodCreate(MethodPara,interfaceNamePara)
        string=string+string2
    return string

 

 3.构造单个测试集:

def singleTestsuitCreate(MethodList,parameters):
    code = Template('''suite.addTest(${className}("test_${testcase}"))''')
    string = code.substitute(testcase = MethodList["testcase"],className = parameters[0])
    return string

 

 4.添加测试集

def addtestsuit(MethodParaList, interfaceNamePara):
    string = ""
    for MethodPara in MethodParaList:
        string2 = singleTestsuitCreate(MethodPara, interfaceNamePara)
        string = string + string2
    return string

 

5.生成测试用例类函数字符串

# 生成测试用例类函数字符串
def modelClassCreate(parameters):
    modelCode = methodCreate(parameters[2], parameters[1])
    adtestsuit = addtestsuit(parameters[2], parameters)
    code = Template('''#coding: utf-8
"""
作者：xxx
功能：待执行的接口测试用例
环境：python2.7.6
用法：通过框架自动触发调用
"""
import unittest,requests,datetime,sys,logging,BSTestRunner,time,os
from Log import Log
class ${className}(unittest.TestCase):
    u"""待测试接口：${interfaceName}"""
    def setUp(self):
        logging.info('-'*5+"begin test"+"-"*5)
    def tearDown(self):
        logging.info('-'*5+"end test"+'-'*5)
    ${model}
if __name__ == "__main__":
    #解决UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 97: ordinal not in range(128)
    reload(sys)
    sys.setdefaultencoding('utf8')
    #构造测试集
    suite = unittest.TestSuite()
    ${testsuite}
    #定义date为日期，time为时间
    date=time.strftime("%Y%m%d")
    time1=time.strftime("%H%M%S")
    now=time.strftime("%Y-%m-%d-%H_%M_%S",time.localtime(time.time()))
    #创建路径
    path='F:/test/study/yaml/test_log/'+now+"/"
    #解决多次执行时报路径已存在的错误
    try:
        os.makedirs(path)
    except:
        if path!= None:
            logging.error(u'当前路径已经存在')
    filename=path+'Report.html'
    fp=file(filename,'wb')
    #日志记录
    Log.log()
    #执行测试
    runner =BSTestRunner.BSTestRunner(stream=fp,title=u'下单平台接口测试用例',description=u'接口用例列表：')
    runner.run(suite)
    fp.close()
''')
    fileStr = code.substitute(className=parameters[0], interfaceName=parameters[1], testsuite=adtestsuit,
                              model=modelCode)
    f = open(parameters[0] + ".py", 'w')
    f.write(fileStr)
    f.close()

 

二、然后测试用例部分如下：

    parameters=["Testcase_Orders",
                "/login",
               [
                    {"TestcaseName":"测试登录","method":"post","url":"http://www.senbaba.cn/login","headers":{'content-type': 'application/json',
                   'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko',
                   'Accept':'application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, */*',
                   'Accept-Language':'zh-CN'},"data":{"uname":"187071484771","pwd":"123456"},
                        "testcase":"login"},
 
                   {"TestcaseName":"测试登录","method":"post","url":"http://www.senbaba.cn/login1","headers":{'content-type': 'application/json',
                   'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko',
                   'Accept':'application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, */*',
                   'Accept-Language':'zh-CN'},"data":{"uname":"187071484771","pwd":"123457"},
                        "testcase":"login_failed"}
                ]]

 

三、自动生成的测试用例如下：

# coding: utf-8
"""
作者：xx
功能：待执行的接口测试用例
环境：python2.7.6
用法：通过框架自动触发调用
"""
import unittest, requests, datetime, sys, logging, BSTestRunner, time, os
from Log import Log


class Testcase_Orders(unittest.TestCase):
    u"""待测试接口：/login"""
    def setUp(self):
        logging.info('-' * 5 + "begin test" + "-" * 5)
    def tearDown(self):
        logging.info('-' * 5 + "end test" + '-' * 5)
    def test_login(self):
        u"""测试登录"""
        headers = {'Accept-Language': 'zh-CN', 'content-type': 'application/json',
                   'Accept': 'application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, */*',
                   'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko'}
        data = {'uname': '187071484771', 'pwd': '123456'}
        re = requests.post(url='http://www.baidu.com/login', headers=headers, data=data)
        status_code = re.status_code
        s = str(status_code)
        json = re.text
        logging.info('-' * 5 + '返回状态码是' + s + '-' * 5)
        logging.info('-' * 5 + '返回结果集是' + json + '-' * 5)
        assert status_code == 200
        assert json['status'] == 'ok'

    def test_login_failed(self):
        u"""测试登录"""
        headers = {'Accept-Language': 'zh-CN', 'content-type': 'application/json',
                   'Accept': 'application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, */*',
                   'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko'}
        data = {'uname': '187071484771', 'pwd': '123457'}
        re = requests.post(url='http://www.baidu.com/login1', headers=headers, data=data)
        status_code = re.status_code
        s = str(status_code)
        json = re.text
        logging.info('-' * 5 + '返回状态码是' + s + '-' * 5)
        logging.info('-' * 5 + '返回结果集是' + json + '-' * 5)
        assert status_code == 200
        assert json['status'] == 'ok'


if __name__ == "__main__":
    # 解决UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 97: ordinal not in range(128)
    reload(sys)
    sys.setdefaultencoding('utf8')
    # 构造测试集
    suite = unittest.TestSuite()

    suite.addTest(Testcase_Orders("test_login"))

    suite.addTest(Testcase_Orders("test_login_failed"))

    # 定义date为日期，time为时间
    date = time.strftime("%Y%m%d")
    time1 = time.strftime("%H%M%S")
    now = time.strftime("%Y-%m-%d-%H_%M_%S", time.localtime(time.time()))
    # 创建路径
    path = 'F:/test/study/yaml/test_log/' + now + "/"
    # 解决多次执行时报路径已存在的错误
    try:
        os.makedirs(path)
    except:
        if path != None:
            logging.error(u'当前路径已经存在')
    filename = path + 'Report.html'
    fp = file(filename, 'wb')
    # 日志记录
    Log.log()
    # 执行测试
    runner = BSTestRunner.BSTestRunner(stream=fp, title=u'下单平台接口测试用例', description=u'接口用例列表：')
    runner.run(suite)

 

四、添加测试集的一个简单方法：

添加测试集：

def addtestsuit(parameters):
    string = ""
    temp = Template('''\n    suite.addTest(${className}("test_${testcase}"))
''')
    l = len(parameters[2])
    for i in range(0,l):
        testcase1 = parameters[2][i]['testcase']
        string2 = temp.substitute(className = parameters[0],testcase = testcase1)
        string=string+string2
        print (string)
        return string
