Betamax 是 VCR 的模仿，用于 HTTP 请求。使用方法：
from betamax import Betamaxfrom requests import Sessionfrom unittest import TestCasewith Betamax.configure() as config: config.cassette_library_dir = 'tests/fixtures/cassettes'class TestGitHubAPI(TestCase): def setUp(self): self.session = Session() self.headers.update(...) # Set the cassette in a line other than the context declaration def test_user(self): with Betamax(self.session) as vcr: vcr.use_cassette('user') resp = self.session.get('https://api.github.com/user', auth=('user', 'pass')) assert resp.json()['login'] is not None # Set the cassette in line with the context declaration def test_repo(self): with Betamax(self.session).use_cassette('repo'): resp = self.session.get( 'https://api.github.com/repos/sigmavirus24/github3.py' ) assert resp.json()['owner'] != {}
