專案結構如下
D:\Gitee\DemoRepo (17.97MB)
+-- testCases (1.03KB)
| +-- conftest.py (252b)
| +-- pmCases (574b)
| | +-- conftest.py (259b)
| | `-- test_logout.py (315b)
頂層conftest.py內容
import pytest
@pytest.fixture(scope='session')
def fix_all():
print('fix_all')
pmCases下的conftest.py內容
import pytest
@pytest.fixture(scope='session', autouse=True)
def fix_all2():
print('fix_all2')
test_logout.py內容
import pytest
def test_logout(fix_all):
print('test_logout')
if __name__ == '__main__':
pytest.main(['-sv',__file__])
用的Pytest7.3.1，而實際7.4.0之前也就只有一個7.3.2了
你是可以執行test_logout.py的
效果如下
test_logout.py::test_logout fix_all2
fix_all
test_logout
PASSED
所以按照以前的認識
注意把pytest更新到pytest7.4.0
同樣執行test_logout.py
效果如下
D:\Gitee\DemoRepo\venv\Scripts\python.exe D:/Gitee/DemoRepo/testCases/pmCases/test_logout.py

很清楚的提示
E fixture 'fix_all' not found
子目錄無法去參照上級目錄的fixture
而同級目錄不受影響
我們的實戰課就會用到子目錄下的測試檔案呼叫上級目錄的fixture，是沒問題的，但現在會受影響。
這是為何呢？第一個想法就是版本變動了。但覺得不太可以理解，正常版本變動對這些邏輯不應該去大改，除非是大版本的改變。因為一旦出現這樣的參照，你以前的專案會無法呼叫。
很多的時候你是在終端下執行
修改test_logout.py
def test_logout(fix_all):
print('test_logout')
終端下執行
D:\Gitee\DemoRepo\testCases>pytest
# 這是成功的
這樣執行
D:\Gitee\DemoRepo\testCases\pmCases>pytest
# 報錯跟上面一樣 E fixture 'fix_all' not found
基於此，如果你是終端下執行的話，其實是沒啥影響的。
只有你要在子目錄下測試或者單獨執行子測試用例時可能會有問題

ExceptionInfo.from_exception(), a simpler way to create an ExceptionInfo from an exception. This can replace ExceptionInfo.from_exc_info() for most uses.#10872: Update test log report annotation to named tuple and fixed inconsistency in docs for pytest_report_teststatus hook.
#10907: When an exception traceback to be displayed is completely filtered out (by mechanisms such as __tracebackhide__, internal frames, and similar), now only the exception string and the following message are shown:
「All traceback entries are hidden. Pass --full-trace to see hidden and internal frames.」.
Previously, the last frame of the traceback was shown, even though it was hidden.
#10940: Improved verbose output (-vv) of skip and xfail reasons by performing text wrapping while leaving a clear margin for progress output.
Added TerminalReporter.wrap_write() as a helper for that.
#10991: Added handling of %f directive to print microseconds in log format options, such as log-date-format.
#11005: Added the underlying exception to the cache provider’s path creation and write warning messages.
#11013: Added warning when testpaths is set, but paths are not found by glob. In this case, pytest will fall back to searching from the current directory.
#11043: When --confcutdir is not specified, and there is no config file present, the conftest cutoff directory (--confcutdir) is now set to the rootdir. Previously in such cases, conftest.py files would be probed all the way to the root directory of the filesystem. If you are badly affected by this change, consider adding an empty config file to your desired cutoff directory, or explicitly set --confcutdir.
#11081: The norecursedirs check is now performed in a pytest_ignore_collect implementation, so plugins can affect it.
If after updating to this version you see that your norecursedirs setting is not being respected, it means that a conftest or a plugin you use has a bad pytest_ignore_collect implementation. Most likely, your hook returns False for paths it does not want to ignore, which ends the processing and doesn’t allow other plugins, including pytest itself, to ignore the path. The fix is to return None instead of False for paths your hook doesn’t want to ignore.
#8711: caplog.set_level() and caplog.at_level() will temporarily enable the requested level if level was disabled globally via logging.disable(LEVEL).
--tb=line mode where pytest.fail(pytrace=False) tests report None.--last-failed whole-file skipping functionality (「skipped N files」) for non-python test files.testpaths to be considered for loading initial conftests, even when it was not utilized (e.g. when explicit paths were given on the command line). Now the testpaths are only considered when they are in use.__tracebackhide__ = True still being shown for chained exceptions (parts after 「… the above exception …」 message).--debug.caplog.set_level().-c to now include --config-file to make it clear that this flag applies to the usage of a custom config file.原文
When `--confcutdir` is not specified, and there is no config file present, the conftest cutoff directory (`--confcutdir`) is now set to the [rootdir](https://docs.pytest.org/en/7.4.x/reference/customize.html). Previously in such cases, `conftest.py` files would be probed all the way to the root directory of the filesystem. If you are badly affected by this change, consider adding an empty config file to your desired cutoff directory, or explicitly set `--confcutdir`.
譯文
當未指定--confcutdir並且沒有組態檔存在時，conftest截斷目錄(--confcutdir)現在被設定為rootdir。在以前的情況下，conftest.py檔案會一直被探測到檔案系統的根目錄。如果你受到這個變化的嚴重影響，考慮在所需的截斷目錄中新增一個空的組態檔，或者明確地設定--confcutdir。
指定引數--confcutdir
範例1: test_logout.py執行
import pytest
def test_logout(fix_all):
print('test_logout')
if __name__ == '__main__':
pytest.main(['-sv','--confcutdir=..',__file__]) # 意思是設定conftest.py的搜尋根目錄是當前目錄上級
範例2: 終端執行
# 你在pmCases下執行
# 如果在專案根目錄下，本來就是ok的
pytest --confcutdir=..
範例3: pytest.ini
[pytest]
# 改為實際的專案根目錄即可
addopts = --confcutdir="D:\Gitee\DemoRepo"
--confcutdir=.(因為你是把pytest.ini放在根目錄下的)截止到撰寫本文的時候(2023-7-10)發現
pip install pytest會安裝最新的Pytest7.4.0
而通過pycharm安裝則是Pytest7.3.1
對於這個引數，命令列--help的解釋是
--confcutdir=dir Only load conftest.py's relative to specified dir
