blu*_*e13 17 python doctest code-coverage
我正在尝试做doctest.'预期'和'得到'结果是相同的,但我的doctest仍然失败.它失败了,因为x-axis y-axis在打印输出之后有一些尾随空格我没有包含在我的文档字符串中.我怎么包括它呢?当我手动插入空格并进行测试时,只要我将光标保持在那里,它就会成功运行.
x轴y轴______________________ [光标在这里]
但是,如果我使用我的光标在其他地方运行测试,则会删除尾随空格并且测试失败.
我知道这听起来很奇怪,但它就是它!
这是代码:
import pandas as pd
import doctest
class NewDataStructure(pd.DataFrame):
"""
>>> arrays = [[1, 1, 2, 2], [10, 20, 10, 20]]
>>> index = pd.MultiIndex.from_arrays(arrays, names=('x-axis', 'y-axis'))
>>> data_input = {"Pressure (Pa)": [1+1j, 2+2j, 3+3j, 4+4j],
... "Temperature": [1, 2, 3, 4]}
>>> new_data_variable = NewDataStructure(data=data_input, index=index, title="Pressures and temperatures")
>>> print new_data_variable
New Data Structure Pressures and temperatures:
Pressure (Pa) Temperature
x-axis y-axis
1 10 (1+1j) 1
20 (2+2j) 2
2 10 (3+3j) 3
20 (4+4j) 4
"""
def __init__(self, data, index, title):
super(NewDataStructure, self).__init__(data=data, index=index)
self.title = title
def __str__(self):
return "New Data Structure {}:\n{}".format(self.title, super(NewDataStructure, self).__str__())
doctest.testmod()

以下是失败时的结果.即使在这里你也应该能够选择之后的区域x-axis y-axis并检测是否有尾随空格.
Failed example:
print new_data_variable
Expected:
New Data Structure Pressures and temperatures:
Pressure (Pa) Temperature
x-axis y-axis
1 10 (1+1j) 1
20 (2+2j) 2
2 10 (3+3j) 3
20 (4+4j) 4
Got:
New Data Structure Pressures and temperatures:
Pressure (Pa) Temperature
x-axis y-axis
1 10 (1+1j) 1
20 (2+2j) 2
2 10 (3+3j) 3
20 (4+4j) 4

我找到了一个使用normalize white space标志的解决方案
把它放在doctest中
>>> print new_data_variable # doctest: +NORMALIZE_WHITESPACE
