说
try:
r = requests.get(url, params={'s': thing})
except requests.ConnectionError, e:
print(e)
如何使用pytest测试except中的行?那是在尝试获取/发布时出现错误的时候?
您需要捕获代码的标准输出(即print
写入的文件)。您可以使用capsys
夹具来执行此操作。
def test_code(capsys):
# Code in which the request will fail
try:
r = requests.get(url, params={'s': thing})
except requests.ConnectionError as e:
print(e)
assert capsys.readouterr().out == "Expected error message"
