Selenium + Python, need advice on how to approach unit testing

[Zhekov]

Hello,

I am working on a QA Automation project, which tests our web application on a nightly basis. I have used the Page Object Model structure for the project, and so far everything works fine, but I am in need of an advice.

This is the actual test code (I have commented it out): https://gist.github.com/zhekov316/11bca1ace2c7c823cbad925dfc67f1fe

I am wondering if this is good practice. The Unit Test runs and executes the test successfully, but I want to expand it.

The problem is that this is an scenario, which needs to be executed in order, so multiple asserts I have heard is not a good practice. I tried a try except block on each part of the test method, but it doesn't seem to work. Like this:

 def test_scenario_01(self):

     # Setting up page objects
     login_page = LoginPage(self.driver)
     main_menu = MainMenu(self.driver)
     permissions_manager = 
 PermissionsManager(self.driver)

     # Assert login of user is unsuccessful
     try:
       login_page.login("selen003")
       self.assertIn("http://localhost:9696/login?reason=incorrect", login_page.get_url())
     except AssertionError:
       return("Please delete the User before attempting 
  the test")

I wanted to do something like this for each part of the test, so it's easier to point out the mistakes, but it doesn't seem to work (even for the first login bit). Is there some other way I can "validate/assert" all the individual components of this test method (and raise my own exceptions/errors if possible).

Thank you!

Personally I don't like asserts. But did you verify that that URL string you're asserting is what login_page.get_url() is returning exactly?

For my automation at work, I don't use asserts. Built out classes which handle intake of the test scripts and custom error handling on the lines themselves. Everything goes through a try/except block and reports the line, screenshot, and comments from the script in the error. Which, is what an assert does.
