pytest是否支持測試名稱中的unicode？

Question

這是我的測試樣品（test_time.py）：

#!/usr/bin/python 
# -*- coding: utf-8 -*- 

import pytest 
from datetime import datetime, timedelta 

testdata = [ 
    (datetime(2001, 12, 12), datetime(2001, 12, 11), timedelta(1)), 
    (datetime(2001, 12, 11), datetime(2001, 12, 12), timedelta(-1)), 
] 

@pytest.mark.parametrize("a,b,expected", testdata, ids=[u"中文", u"English"]) 
def test_timedistance_v1(a, b, expected): 
    diff = a - b 
    assert diff != expected 

這裏是pytest輸出：

============================================================================== FAILURES ============================================================================== 
_________________________________________________________________ test_timedistance_v1[\u4e2d\u6587] _________________________________________________________________ 

a = datetime.datetime(2001, 12, 12, 0, 0), b = datetime.datetime(2001, 12, 11, 0, 0), expected = datetime.timedelta(1) 

    @pytest.mark.parametrize("a,b,expected", testdata, ids=[u"中文", u"English"]) 
    def test_timedistance_v1(a, b, expected): 
     diff = a - b 
>  assert diff != expected 
E  assert datetime.timedelta(1) != datetime.timedelta(1) 

test_time.py:15: AssertionError 
___________________________________________________________________ test_timedistance_v1[English] ____________________________________________________________________ 

a = datetime.datetime(2001, 12, 11, 0, 0), b = datetime.datetime(2001, 12, 12, 0, 0), expected = datetime.timedelta(-1) 

    @pytest.mark.parametrize("a,b,expected", testdata, ids=[u"中文", u"English"]) 
    def test_timedistance_v1(a, b, expected): 
     diff = a - b 
>  assert diff != expected 
E  assert datetime.timedelta(-1) != datetime.timedelta(-1) 

test_time.py:15: AssertionError 
====================================================================== 2 failed in 0.05 seconds ====================================================================== 

對於輸出的第二線，所述測試名稱是「test_timedistance_v1 [\ u4e2d \ u6587]「，我希望它是」test_timedistance_v1 [中文]「，py.test是否支持它？ （我的pytest版本是3.1.2，操作系統：macOS 10.12.5）

它不取決於pytest，但取決於您的計算機語言環境。

這裏測試的跟蹤日誌（LC_ALL = 「的en_US.UTF-8」）：

================================ test session starts ================================ 
platform linux -- Python 3.5.3, pytest-2.9.2, py-1.4.34, pluggy-0.3.1

pytest_chin.py FF 

===================================== FAILURES ======================================

而與LC_ALL = 「fr_FR.iso8859-1」：

================================ test session starts ================================
