In this installment, I try to use the Python standard library module doctest and unittest to improve the testing in my utility toolset and lead you to experience with me (and point out some of the best methods). Script gnosis/xml/objectify/test/test_basic.py gives a typical example of the shortcomings of the current test and the solution. The following is the lates

Use the unittest and doctest modules in Python, unittestdoctest I want to be honest. Although I am the creator of a Python library in a widely used public domain, the unit tests introduced in my modules are very unsystematic. In fact, most of those tests are included in gnosis Utilities of Gnosis. xml. pickle and are written by contributors to this sub-package. I also found that the vast majority of third-party Python packages I downloaded lacked a co
