Python unittest并发执行依赖用例（修改少量源码）

在设计自动化脚本时，曾想过如何并发的执行测试用例，一般情况下是使用多线程，还行协程呢？如果使用协程，因为它异步的运行方式，我们必须先将所有主case依赖数据提前生成（为了防止有重复依赖数据，必须要生成唯一id,不然后果可会被覆盖），也就是在最后一步使用协程请求,需要改一些unittest底层源码。如果使用多线程，我们只需要将互相依赖的case按照依赖顺序组成Suite，在传入运行方法中，将底层运行的方法改成多线程，运行即可~最终效果如下，并发执行效率提高了很多：

  • 先简单讲一下协程，实现方式这次就不着重讲啦~(因为自己没有具体实现过)，由于它异步的运行方式，我们必须先将所有主case依赖数据提前生成,请看下图,也就是在如图所示的位置使用协程，我在网上找到了一篇文章有相关介绍:点我   ，但此文章中只考虑到了单一接口的执行，所以在运行依赖接口时，需要在使用协程之前执行完毕~（有能力的童鞋可以自己试试呀~)

  • 接下来我们着重讲一下如何用多线程执行unittest,这次还是使用之前文章Python 40行代码实现HttpRunner(动态创建类,动态添加方法,模板解析）中的接口与基本脚本，为了让执行时间更加明显，我们把这次的接口全部加time.sleep(1),部分代码截图如下（详细请看之前文章）： 
    @app.route('/DepenceOne', methods=['GET'])
def DepenceOne():
    if request.method == "GET":
        time.sleep(1)
        return jsonify({'One': A})

@app.route('/DepenceTwo', methods=['POST'])
def DepenceTwo():
    if request.method == 'POST':
        data = request.get_data()
        json_data = json.loads(data.decode("utf-8"))
        time.sleep(1)
        return jsonify({'Two': B+int(eval(json_data)['One'])})

@app.route('/DepenceThr', methods=['GET'])
def DepenceThr():
    if request.method == "GET":
        time.sleep(1)
        return jsonify({'Thr': C})

@app.route('/DepenceFou', methods=['POST'])
def DepenceFou():
    if request.method == 'POST':
        data = request.get_data()
        json_data = json.loads(data.decode("utf-8"))
        time.sleep(1)
        return jsonify({'Fou': D+int(eval(json_data)['Thr'])})

@app.route('/DepenceFive', methods=['POST'])
def DepenceFive():
    if request.method == 'POST':
        data = request.get_data()
        json_data = json.loads(data.decode("utf-8"))
        if int(eval(json_data)['Two'])+int(eval(json_data)['Fou'])==10:
            time.sleep(1)
            return jsonify({'data':'success'})
  • 接口依赖关系为：

  • 我们在Python 40行代码实现HttpRunner(动态创建类,动态添加方法,模板解析）中使用的是loadTestsFromModule来加载py文件中的测试类，然后全部放入一个suite中在使用HTMLTestRunner（HTMLTestReportCN.py下的一个类，由于HTMLTestReportCN被我改写过了，且里面加了很多逻辑，直接拿来用不了~原版的请百度一下下载吧~）去执行，如果采用多线程，则需要将py问中的测试类（已经组装好依赖方法）独立分成多个suite,在传入HTMLTestRunner中，并修改其中的执行方法即可,因此我们修改一下我们之前的代码，将其改为使用loadTestsFromTestCase去加载: 
    for class_name in [str(i) for i  in class_dict.keys() if i not in('Log', 'ConfigReader', 'sqlconnect', 'OutputRedirector', 'Template_mixin', 'TestResult', 'HTMLTestRunner', 'TestProgram', 'main', 'Depence')]: #取出当前继承unittest的class
    n=1
    for def_data in eval(load_yaml_case()[f'{class_name}.yaml']): #取出当前继承unittest的class的testcase data
        setattr(eval(class_name), 'test_%s_func_%s' % (n,def_data['name']), getTestFunc(**def_data['request'])) #将testcase data转成def
        n+=1
    suite = unittest.TestLoader().loadTestsFromTestCase(eval(class_name)) 
  • 接下来我们看一下HTMLTestRunner中的run方法(执行suite的方法)，由此可见将test=suite传入后，并传入一个result后执行。那我们现在只需要将其test改成一个list,让其中包含多个suite。 
    def run(self, test):
    "Run the given test case or test suite."
    result = _TestResult(self.verbosity)
    test(result)
    self.stopTime = datetime.datetime.now()
    self.generateReport(test, result)
    # print('\nTime Elapsed: %s' % (self.stopTime - self.startTime), file=sys.stderr)
    return result
  • 修改源码,传入list,并加入多线程如下： 
    def run(self, test:list):
    "Run the given test case or test suite."
    result = _TestResult(self.verbosity)
    threadings = []
    for func in test:
        t = threading.Thread(target=func, args=(result,))
        threadings.append(t)
    for j in threadings:
        j.start()
    for j in threadings:
        j.join()
    self.stopTime = datetime.datetime.now()
    self.generateReport(test, result)
    # print('\nTime Elapsed: %s' % (self.stopTime - self.startTime), file=sys.stderr)
    return result
  • 接下来我们来生成多个suite，修改Python 40行代码实现HttpRunner(动态创建类,动态添加方法,模板解析）中的源码，加入suietlist，装载不同的suite： 
    suitelist=[]
print([str(i) for i  in class_dict.keys()])
for class_name in [str(i) for i  in class_dict.keys() if i not in('Log', 'ConfigReader', 'sqlconnect', 'OutputRedirector', 'Template_mixin', 'TestResult', 'HTMLTestRunner', 'TestProgram', 'main', 'Depence')]: #取出当前继承unittest的class
    n=1
    for def_data in eval(load_yaml_case()[f'{class_name}.yaml']): #取出当前继承unittest的class的testcase data
        setattr(eval(class_name), 'test_%s_func_%s' % (n,def_data['name']), getTestFunc(**def_data['request'])) #将testcase data转成def
        n+=1
    suite = unittest.TestLoader().loadTestsFromTestCase(eval(class_name))
    suitelist.append(suite)
  • 最后将suitelist传入经过我们修改过的HTMLTestRunner下run方法运行即可~ 
    with open(report_file + r'\TestReport2.html', 'wb') as f:  # 从配置文件中读取
   HTMLTestRunner(stream=f, title='Api Test', description='动态类demo', tester='ayo').run(suitelist)
  • 运行结果，每个接口返回时间>=1s的情况下，只花了5s，执行了25个接口。嘻嘻是不是要比单线程要快很多呢~

  455. Всем привет, хочу порекомендовать вам хороший сайт о Форексе
    С недавних пор так называемые «консультационные центры», которые аферисты из ФорексШарм расплодили по всей стране, стали активно рекламировать доселе неизвестного «инновационного брокера» ФорексШарм ( ). Посмотрим на эту контору повнимательней. Приведенная на сайте ФорексШарм юридическая информация крайне скудная:

    ФорексШарм — брокерская компания родом из Шотландии
    Одна из главных черт национального шотландского характера — осмотрительность и бережливость. Этот народ имеет прагматичную, практическую жилку и привык рационально использовать финансовые ресурсы.

    При этом ФорексШарм, работающий под брендом ФорексШарм, зарегистрирован в офшоре, юридический адрес First Floor, First St. Vincent Bank Building, James Street, Kingstown, St. Vincent and the Grenadines. Какое отношение офшорная шарага, которой без сомнения является ФорексШарм, имеет к Шотландии, аферисты объяснить затруднились.

    Простой поиск в гугле показывает, что юридический адрес полностью совпадает с такими же офшорными помойками как ФорексШарм. Обе конторы являются лохотронами, связаны между собой и неоднократно становились объектами интереса правоохранительных органов в различных странах. Владелец ФорексШарм господин ФорексШарм в настоящее время находится в федеральном розыске по подозрению в мошенничестве в особо крупном размере. ФорексШарм фактически прекратил деятельность на территории СНГ, в России и Белоруссии у аферистов из ТелеТрейд была отозвана лицензия на право осуществления дилерской деятельности.

    ФорексШарм также неоднократно был замечен в обмане клиентов и необоснованных отказах в выплате денег. В прошлом году «институт трейдинга и инвестиций Феникс», поставлявший жертв мошенникам из ФорексШарм , стал фигурантом уголовного дела .

    Информация с сайта ФорексШарм:

    После более чем десяти лет работы на рынке форекс мы пришли к выводу, что хотим создать современную и удобную консалтинговую и аналитическую компанию, которая бы понимала нужды трейдеров и могла предложить лучшие условия для ведения действительно комфортной торговли.

    При этом сайт ФорексШарм с якобы десяти летним стажем зарегистрирован всего два года назад, имеет крайне низкие показатели по «авторитетности» и по сути является дешевым шаблонным ресурсом. Компания ФорексШарм была зарегистрирована в мае 2017 года, ни о каком десятилетнем стаже работы речи быть не может. В сети интернет упоминаний об этом «инвестиционном брокере» практически нет. Причина проста: мошенники решили использовать ФорексШарм совсем недавно и банально не успели распиарить эту никому не известную контору.

    Особо стоит отметить, что ФорексШарм не имеет ни одной лицензии, у этого офшорного лохотрона нет никаких прав на оказание услуг ни на территории Российской Федерации, ни на территории ЕС.

    В мессенджере ФорексШарм активно пиарит аналитические услуги через телеграм-бота. Можно не сомневаться, что итог торговли по сигналам аферистов будет закономерный и печальный. Заработать, доверяя деньги мошенникам, невозможно.

    Вывод

    ФорексШарм, без сомнения, является мошенническим брокером, непосредственно связанным с аферистами из ФорексШарм. Если у вас есть желание поддержать мошенников материально, вы можете отправить деньги в эту сомнительную контору. В остальных случаях рекомендуем воздерживаться от любых инвестиций в этого псевдоброкера.

    3. Возможность обучения для трейдеров с различным опытом.
    4. Отсутствие рисков и гарантия безопасности средств.
    5. Удобный вводи вывод средств.
    Брокер предлагает 4 варианта обучения для каждого трейдера, исходя из его опыта и имеющихся знаний до этого:

    1. Базовый курс: «Основы анализа финансовых рынков».
    2. Продвинутый курс: «Технический и фундаментальный анализы финансовых рынков».
    3. Профессиональный курс: «Построение торговых систем и тактик».
    4. Экспертный курс: «Мастер-класс».
    Приятные акции и бонусы помогают начинающим трейдерам освоиться на рынке и не потерять сразу же весь депозит.

    Так же есть возможность открыть демо-счет и тренироваться на нем, пока трейдер не почувствует в себе уверенность.
