assertpy features and specs

Fluent API
Assertpy offers a fluent API that makes assertions more readable and expressive, enabling developers to write assertions in a natural language style that is easy to understand.
Chainable Assertions
It allows for chainable assertions, enabling multiple checks to be performed in a single line of code, thereby reducing verbosity and enhancing clarity.
Comprehensive Assertion Methods
The library provides a wide range of built-in assertion methods, catering to various types of data validations, such as checking for size, type, value, and more.
Extensibility
Assertpy supports extending its functionality by defining custom assertions, allowing developers to tailor it to their specific needs.
Pythonic
Designed with Pythonic principles in mind, Assertpy fits seamlessly into Python projects, enabling idiomatic and consistent code style.

Possible disadvantages of assertpy

Learning Curve
Developers new to the library may encounter a learning curve due to the distinct approach of using fluent and chainable assertions as opposed to traditional methods.
Limited by Python Version
The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
Performance Overhead
The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
Less Community Support
Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
Dependency Management
Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.

How Changing Requirements Shape the Infrastructure of a Software Project
So I started designing the DB using this cool tool. The project has 2 tables, users and categories .

Newbie: Trying to use Supabase Auth fully with its database.
To be honest, since you are just getting started, I think you should reconsider simplifying this app to begin with. Built something easier and get some more experience before jumping in the ocean.
