這篇文章將為大家詳細講解有關如何在pytest中使用pytest.ini配置文件,文章內容質量較高,因此小編分享給大家做個參考,希望大家閱讀完這篇文章后對相關知識有一定的了解。
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
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執行
pytest --help
找到這部分內容

就放在項目根目錄下 ,不要亂放,不要亂起其他名字
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
未設置 xfail_strict = True 時,測試結果顯示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 ==============================
已設置 xfail_strict = True 時,測試結果顯示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輸入一堆指令去執行用例的時候,就可以用該參數代替了,省去重復性的敲命令工作
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 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的運行結果
log_cli=1的運行結果
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!!!但如果拿去批量跑測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 參數簡化 pytest 的搜索工作【還是挺有用的!!!】
默認設置: 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
pytest默認的測試用例收集規則
文件名以 test_*.py 文件和 *_test.py
以 test_ 開頭的函數
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則的;當然啦,是建議在原有的規則上添加的,如下配置
[pytest] python_files = test_* *_test test* python_classes = Test* test* python_functions = test_* test*
