我的項目有以下結構:的Python - InvocationError在TOX運行py.test和覆蓋測試

my_project 
| 
setup.py 
tox.ini 
src 
    | 
    core_functions.py 
    client.py 
    server.py 
    sql_database.py 
    tests.py 

tests.py文件包含在文件client.py, server.py, sql_database.py, core_functions.py

下一頁所有功能測試,我創建我想用於py.testscoverage tests的自動化的tox.ini文件。該tox.ini文件的結構如下:

[tox] 
envlist = py27,cov 

[testenv] 
commands = py.test -sv --doctest-modules my_project/__init__.py my_project/tests.py 


[testenv:py27] 
commands = coverage erase 
      coverage run --source=my_project -m pytest 
      coverage report -m 
deps = pytest 

當我在命令行tox的py.tests成功運行,但覆蓋測試失敗,出現以下錯誤:

我如何修復我的tox.ini文件以使其工作?

我沒有看到任何錯誤。複製/粘貼不足? – phd

@phd看看以'收集10334個項目/ 167個錯誤ERROR'開始的行# – Ziva

啊,對不起。似乎pytest在進口時發現了167個錯誤。 pytest測試通過沒有tox? – phd

問題是你的兩個調用之間的差異。

[testenv]你基本上美其名曰:

py.test -sv --doctest-modules my_project/__init__.py my_project/tests.py 

但等效採用覆蓋你只是運行:

py.test 

py.test不帶參數會從當前目錄,並嘗試遞歸發現測試。這通常不是你想要什麼(你不關心測試STDLIB,和所有的依賴,你已經加入的virtualenv等)

如果您從其他調用添加參數您的覆蓋範圍行將按照您的意願行事:

coverage run --source=my_project -m pytest -sv --doctest-modules my_project/__init__.py my_project/tests.py
