我正在尝试测试用例来模拟 api 调用并使用 python 响应来模拟 api 调用。

下面是我的模拟,

with responses.RequestsMock() as rsps:
    url_re = re.compile(r'.*udemy.com/api-2.0/courses.*')           
    url_re = re.compile(r'https://www.udemy.com/api-2.0/courses')
    rsps.add(
        responses.GET, url_re,
        body=mocked_good_json, 
        status=200,
        content_type='application/json',
        match_querystring=True
    )
    courses = self.app.courses.get_all(page=1, page_size=2)         
    for course in courses:              
        self.assertTrue(isinstance(course, Course))
        self.assertTrue(hasattr(course, 'id'))
        self.assertTrue(hasattr(course, 'title'))           
        self.assertIsNotNone(course.id)        

当我执行这个模拟时,我得到这个错误 -

AssertionError: Not all requests have been executed [(u'GET', 'https://www.udemy.com/api-2.0/courses/')]

当我删除模拟并直接调用 api 时,它工作正常。

关于为什么我的模拟失败的任何输入?

错误信息 -

您正在模拟请求,但在此测试中未调用该请求。您正在调用courses = self.app.courses.get_all (page = 1, page_size = 2),我怀疑此方法courses.get_all正在调用请求库。

根据docs,在为模拟添加响应后,预计会调用该请求。而且你不是在调用 request 之后,而是在调用get_all,并且这个方法正在调用 requests。

所以,你必须移动这个测试,并调整它、get_all方法或模拟来自使用它的类的请求,看看你的代码,我想在Course.get_all.
