前言
pytest配置文件可以改變pytest的運行方式，它是一個固定的文件pytest.ini文件，讀取配置信息，按指定的方式去運行
非test文件
pytest里面有些文件是非test文件
- pytest.ini：pytest的主配置文件，可以改變pytest的默認行為
- conftest.py：測試用例的一些fixture配置
- _init_.py：識別該文件夾為python的package包
查看pytest.ini的配置選項
cmd執(zhí)行

pytest.ini應(yīng)該放哪里？
就放在項目根目錄下 ，不要亂放，不要亂起其他名字
接下來講下常用的配置項
marks
作用：測試用例中添加了 @pytest.mark.webtest 裝飾器，如果不添加marks選項的話，就會報warnings
格式：list列表類型
寫法：
[pytest]
markers =
weibo: this is weibo page
toutiao: toutiao
xinlang: xinlang
xfail_strict
作用：設(shè)置xfail_strict = True可以讓那些標記為@pytest.mark.xfail但實際通過顯示XPASS的測試用例被報告為失敗
格式：True 、False（默認），1、0
寫法：
[pytest]
# mark標記說明
markers =
weibo: this is weibo page
toutiao: toutiao
xinlang: xinlang
xfail_strict = True
具體代碼栗子
未設(shè)置 xfail_strict = True 時，測試結(jié)果顯示XPASS
@pytest.mark.xfail()
def test_case1():
a = "a"
b = "b"
assert a != b
collecting ... collected 1 item
02斷言異常.py::test_case1 XPASS [100%]
============================= 1 xpassed in 0.02s ==============================
已設(shè)置 xfail_strict = True 時，測試結(jié)果顯示failed
collecting ... collected 1 item
02斷言異常.py::test_case1 FAILED [100%]
02斷言異常.py:54 (test_case1)
[XPASS(strict)]
================================== FAILURES ===================================
_________________________________ test_case1 __________________________________
[XPASS(strict)]
=========================== short test summary info ===========================
FAILED 02斷言異常.py::test_case1
============================== 1 failed in 0.02s ==============================
addopts
作用：addopts參數(shù)可以更改默認命令行選項，這個當我們在cmd輸入一堆指令去執(zhí)行用例的時候，就可以用該參數(shù)代替了，省去重復(fù)性的敲命令工作
比如：想測試完生成報告，失敗重跑兩次，一共運行兩次，通過分布式去測試，如果在cmd中寫的話，命令會很長
pytest -v --rerun=2 --count=2 --html=report.html --self-contained-html -n=auto
每次都這樣敲不太現(xiàn)實，addopts就可以完美解決這個問題
[pytest]
# mark
markers =
weibo: this is weibo page
toutiao: toutiao
xinlang: xinlang
xfail_strict = True
# 命令行參數(shù)
addopts = -v --reruns=1 --count=2 --html=reports.html --self-contained-html -n=auto
加了addopts之后，我們在cmd中只需要敲pytest就可以生效了??！
log_cli
作用：控制臺實時輸出日志
格式：log_cli=True 或False（默認），或者log_cli=1 或 0
log_cli=0的運行結(jié)果
log_cli=1的運行結(jié)果
結(jié)論
很明顯，加了log_cli=1之后，可以清晰看到哪個package下的哪個module下的哪個測試用例是否passed還是failed；
所以平時測試代碼是否有問題的情況下推薦加?。。〉绻萌ヅ颗軠y試用例的話不建議加，誰知道會不會影響運行性能呢？
norecursedirs
作用：pytest 收集測試用例時，會遞歸遍歷所有子目錄，包括某些你明知道沒必要遍歷的目錄，遇到這種情況，可以使用 norecursedirs 參數(shù)簡化 pytest 的搜索工作【還是挺有用的?。?！】
默認設(shè)置： norecursedirs = .* build dist CVS _darcs {arch} *.egg
正確寫法：多個路徑用空格隔開
[pytest]
norecursedirs = .* build dist CVS _darcs {arch} *.egg venv src resources log report util
更改測試用例收集規(guī)則
pytest默認的測試用例收集規(guī)則
- 文件名以 test_*.py 文件和 *_test.py
- 以 test_ 開頭的函數(shù)
- 以 Test 開頭的類，不能包含 __init__ 方法
- 以 test_ 開頭的類里面的方法
我們是可以修改或者添加這個用例收集規(guī)則的；當然啦，是建議在原有的規(guī)則上添加的，如下配置
[pytest]
python_files = test_* *_test test*
python_classes = Test* test*
python_functions = test_* test*
