我正在为以下函数编写pytest单元测试
from datetime import datetime
def validate_timestamp(timestamp):
"""Confirm that the passed in string is in the proper format %Y%m%d_%H"""
try:
ts = datetime.strptime(str(timestamp),'%Y%m%d_%H')
except:
raise ValueError("{0} must be in the format `%Y%m%d_%H".format(timestamp))
return datetime.strftime(ts,'%Y%m%d_%H')
我如何测试格式错误的时间戳?为此写出最好的单元测试是什么?
答案 0 :(得分:2)
运行预期会在with
块中引发异常的代码,如:
with pytest.raises(ValueError):
# code
