importing modules to be tested
by Alex Kleider Jan. 11, 2024

Jan. 11, 2024

It's been my impression that tests are usually placed in their own separate directory. The problem then arises how to import the modules that are to be tested. My solution has been to use the following code: """ import os import sys sys.path.insert(0, os.path.split(sys.path[0])[0]) """ Is there a "better way?" I'm using Debian/GNU/Linux and python 3.9 Thanks in advance for any advice you might have. Sincerely, Alex Kleider The following may or may not be helpful as background: $ pwd /home/alex/Git/Lib/Question $ ls -lA total 28 -rwxr-xr-x 1 alex alex 100 Jan 10 12:25 code2test.py drwxr-xr-x 2 alex alex 4096 Jan 10 12:26 tests $ cat code2test.py #!/usr/bin/env python3 # file: code2test.py def code(): return "code2test.code() has been run" $ cat tests/test_code.py #!/usr/bin/env python3 # File: tests/test_code.py import os import sys sys.path.insert(0, os.path.split(sys.path[0])[0]) import code2test assert code2test.code() == "code2test.code() has been run" print("Test passes") $ ./tests/test_code.py Test passes $ cat tests/test_code.py #!/usr/bin/env python3 # File: tests/test_code.py """ import os import sys sys.path.insert(0, os.path.split(sys.path[0])[0]) """ import code2test assert code2test.code() == "code2test.code() has been run" print("Test passes") $ ./tests/test_code.py Traceback (most recent call last): File "/home/alex/Git/Lib/Question/./tests/test_code.py", line 8, in <module> import code2test ModuleNotFoundError: No module named 'code2test' -- alex(a)kleider.ca (he/him) (sent from my current gizmo)

import issues
by James Hartley Jan. 10, 2024

Jan. 10, 2024

I admit that I have not internalized how Python's import system works yet. Given the following directory structure: +-project | +-src | | | +-__init__.py | +-foo.py | +-tests | +-test_foo.py Currently, __init__.py is empty. What needs to be placed in __init__.py and test_foo.py in order for pytest to execute all tests in test_foo.py? pytest is being executed while in the project directory. With: from foo import Foo --or-- from src.foo import Foo defined in test_foo.py, pytest reports "ModuleNotFoundError: No module named 'src'". Any and all comments would be appreciated. Any links to online sources would also be appreciated. Thanks! j

Class definitions
by dn Jan. 2, 2024

Jan. 2, 2024

Are you training folk, or requiring in Code Reviews, the use of parentheses in stand-alone class definitions (or not)? The non-responsive fellow wrote a function-definition as: def prnt: (twice!) which is plainly incorrect because the def, the parentheses, and the colon are all compulsory [as discussed, elsewhere] - even if the parameter-list is empty. funcdef ::= [decorators] "def" funcname [type_params] "(" [parameter_list] ")" ["->" expression] ":" suite Whereas, a class-definition requires only the class and a colon. In this case, parentheses are only needed to delimit an inheritance argument-list. classdef ::= [decorators] "class" classname [type_params] [inheritance] ":" suite inheritance ::= "(" [argument_list] ")" That said, and IIRC carrying-over from Python2, the inheritance argument-list is separately optional. In other words, one may express an empty set of parentheses. Accordingly, this old-timer's personal habit/muscle-memory(?) is to type them quite unconsciously. - or maybe some vague-idea that they just might be needed in-future in the same way that we add commas after the last element of lists in case of later additions-and-alterations? Conversely: over the years, I've occasionally noted newcomers becoming confused between function-definitions and class-definitions. Not between function and class as constructs, but between (function) parameter-lists and (class) inheritance argument-lists. Accordingly, wondered if you feel there is virtue in writing class-names without parentheses, and only moving to such syntax upon reaching more advanced levels involving inheritance (and multiple-inheritance)?

tkinter designer
by Mats Wichmann Dec. 29, 2023

Dec. 29, 2023

Ran across this elsewhere... people here sometimes ask about why a tkinter design attempt doesn't come out as expected. It seems someone has made an effort at building a designer for tkinter: https://github.com/ParthJadhav/Tkinter-Designer it's on PyPi as tkdesigner. Have no experience with it, but maybe it might of some use to someone someday... It uses another project which has a free tier but also paid versions, just so that's mentioned.

Hi All , I am planning to automate a daily task on a App . The objective is build a python script to Configure the HTTP Request to simulate the interactions with the web application. This might involve sending POST requests, handling cookies, etc I am planning to use this python script with Selenium . I need some guidance or links which can make me understand how to write apython script to simulate the interactions with the web application like login and authentication to https://hudle.in and use then use the booking using SSO or OTP .
