对kotti_image项目进行pytest测试操作实践（失败）
对kotti_image项目进行pytest测试操作实践
因为前期在升级kotti_image到kotti_image2的过程中，pytest报错，于是准备在kotti_image下先试用pytest测试一下，以便解决kotti_image2 测试报错的问题。
系统Ubuntu22.04
python环境：python3.12
后改成python3.10 ，后又改成python3.9 ，但是都测试没通过.....估计是kotti_image太老了，跟很多库不匹配导致的。
源码安装kotti
git clone https://gitcode.com/gh_mirrors/ko/Kotticd Kotti
pip install -r requirements.txt源码安装kotti_image
首先fork kotti_image项目到自己的账号，
git clone下载到本地：
git clone https://github.com/skywalk163/kotti_image进入目录，pip安装
cd kotti_image
pip install -e .
显示输出
pip install -e .
Defaulting to user installation because normal site-packages is not writeable
Looking in indexes: https://pypi.tuna.tsinghua.edu.cn/simple
Obtaining file:///home/skywalk/github/kotti_imageInstalling build dependencies ... doneChecking if build backend supports build_editable ... done安装附加库
pip install mock
pip install pytest-cov
pip install webtest安装测试库
pip install -e ".[testing]"到了这才明白，原来测试需要安装测试库，怪不得在项目根目录找不到测试需要安装的库，原来是写到setup.py文件里面了，需要使用 pip install -e ".[testing]" 语句来安装
最终
安装Kotti==2.0.9
pip install Kotti==2.0.9 --break-system-packages然后测试的时候加上这句：
pytest -p no:typeguard调试

AttributeError: module 'sqlalchemy.ext.baked' has no attribute 'bake_lazy_loaders'一看，sqlachemy的版本不对啊！当前是：SQLAlchemy 2.0.41
kotti需要的是：SQLAlchemy==1.4.36
用pip安装kotti，版本无法控制住，一定要pip install安装，才能控制住版本。
pytest报错error: unrecognized arguments: --cov=kotti_image --cov-report=term-missing --cov-config kotti_image/tests

安装必要插件
pip install pytest-cov

尝试
pip install -e ".[testing]"
这回的pytest又有了新进展，有如下报错
pytest kotti_image报错ModuleNotFoundError: No module named 'imp'

- 在 Python 3.4 及以后的版本中，
imp模块已被标记为过时（deprecated），并在 Python 3.10 中被完全移除。
当前Name: pytest

是不是pytest版本太低的缘故？
升级到5.3.3
pytest升级到5.3.3报错：TypeError: required field "lineno" missing from alias

TypeError: required field "lineno" missing from alias
根本原因 Python 3.12兼容性问题：
不对啊，我是python3.10啊，去看了一下，晕，怎么又变成python3.12啦！
换成python3.10 有报错：
，这回的3.10有点特殊，所以用路径来使用：
/usr/bin/python3.10 -m pytest原来是pytest-4.6.11
换成5.3.3
/usr/bin/python3.10 -m pip install pytest==5.3.3现在的问题是5.3.3在python3.10下也是报错 TypeError: required field "lineno" missing from alias
升级到新版本：
/usr/bin/python3.10 -m pip install --upgrade pytest pytest-covSuccessfully installed pluggy-1.6.0 pytest-8.4.1 pytest-cov-6.2.1 pytest-xdist-3.7.0现在报错
FAILED kotti_image/tests/test_functional.py::test_add_images - NotImplementedError: Can't perform this operation for unregistered loader type
FAILED kotti_image/tests/test_functional.py::TestTween::test_tween - AttributeError: seek
重新安装了python3.9版本环境，测试报错TypeError: __call__() got an unexpected keyword argument 'wrapper'
报错

TypeError: __call__() got an unexpected keyword argument 'wrapper'- 根本原因：
pytest-cov版本与pytest主版本不匹配uv管理的环境中可能存在版本冲突
安装pytest-cov 4.1.0版本
pip install pytest-cov==4.1.0 --break-system-packages有了改观....
问题先总结一下
现在kotti 手工安装的时候是Kotti-2.0.10.dev0
kotti_image手工安装的时候依赖kotti是Kotti-2.0.9
而且类似sqlalchemy这样的，版本一弄就升到2.x，又要手工降低回1.4.36版...
报错：ImportError: cannot import name 'DBSession' from 'kotti' (unknown location)
测试了一下，竟然没法import kotti ，什么情况？
安装一下
pip install Kotti==2.0.9 --break-system-packages然后测试的时候加上这句：
pytest -p no:typeguardpytest -p no:typeguard报错：__init__.py:205: SAWarning: transaction already deassociated from connection
报错很多测试失败分析与解决方案
1. 测试失败详情
在 TestTween.test_tween 测试中，出现了一个 AttributeError，错误发生在尝试调用 seek方法时。错误信息如下：
text
Copy Code
1
AttributeError: seek
该错误源于 cgi.py 文件中的 FieldStorage 对象，该对象没有 seek 方法。错误堆栈显示，这个问题发生在处理图像数据时，特别是在 depot.io.utils.py 的 file_from_content 函数中尝试将内容重置到文件开头时。
2. 错误原因分析
数据类型不匹配：FieldStorage 对象通常用于处理通过 HTTP POST 请求上传的文件。在这里，它似乎被错误地用作了包含原始图像数据的对象。
图像数据处理不当：在 test_tween 测试中，图像数据是通过 image_asset.read() 读取的，这可能返回了一个字节串（bytes），而不是一个文件对象。
3. 解决方案
确保数据类型正确：检查 image_asset 的来源和类型，确保它是一个文件对象，或者如果它是一个字节串，需要适当地将其转换为文件对象或处理为字节数据。
修改测试代码：如果 image_asset 是一个字节串，你可以考虑使用 io.BytesIO 将其封装为一个类文件对象，这样它就可以支持 seek 方法了。
例如：
from io import BytesIO# 假设 image_asset.read() 返回的是字节串
image_data = image_asset.read()
image_file = BytesIO(image_data)# 然后将 image_file 传递给 Image 构造函数
root["img"] = Image(data=image_file, title="Image")
检查其他相关代码：确保 Image 类的 data 属性能够正确处理类文件对象或字节串。
4. 警告信息
此外，测试还产生了一个警告：
text
Copy Code
1
SAWarning: transaction already deassociated from connection
这个警告通常与 SQLAlchemy 的事务管理有关，可能是在事务已经结束后尝试执行回滚操作。虽然这个警告不会直接导致测试失败，但建议检查相关的数据库操作代码，确保事务被正确管理。
5. 总结
修改测试代码以确保正确处理图像数据。
检查数据库操作代码以管理事务。
重新运行测试以验证问题是否已解决。
暂时放弃！
