我有一个模拟来自不存在的远程服务器的请求的测试:
@httpretty.activate
def test_no_such_host(self):
def no_such_host(request, uri, headers):
raise requests.ConnectionError()
httpretty.register_uri(
'GET',
EXAMPLE_WEBFINGER_URL,
status=200,
headers = {
'Content-Type': 'application/jrd+json',
},
body = no_such_host,
)
webfinger = get_webfinger(
EXAMPLE_USERNAME,
EXAMPLE_HOSTNAME,
)
self.assertEqual(
webfinger.url,
None,
)
get_webfinger
实际上确实抓住了ConnectionError
。当它运行时,测试通过——但它也报告ConnectionError
异常来自 httpretty 线程:
Creating test database for alias 'default'...

单元测试或正在测试的代码中没有线程。这是许多类似测试之一。那些不涉及异常的都运行得很好。
我怎样才能让它停止打印异常?
