Project mention: Ask HN: How do you deal with large Python code bases? | news.ycombinator.com | 2023-05-28
The larger your codebase gets the more bazel becomes a requirement. Bazel is really not negotiable for large python code bases. The more bazel is put off, the more pain you will endure before you eventually are forced to use bazel. You will be forced to use bazel or a system like it because eventually your good devs will not tolerate your codebase and leave without it.
Other than bazel you will have to start hacking away at dependency problems.
No inline imports, no circular imports. Imports all sorted at the top of your file. You will have to start enforcing good hygiene with linters.
You will need to create warnings against using the global scope.
You will need to construct the clients for all your dependencies in main()
You will need to discourage the use of calling non trivial functions in constructors. (this property largely encourages dependency injection).
There are exceptions to every rule, but if you are going to violate scope or not dependency inject, those things need to be done very mindfully.
As the structure of your code improves via good scoping and injected dependencies, it will become easier to change and easier to test.
You will have to devote some serious consideration to how to quarantine business logic from server code. Generally, your product developers shouldn't be doing much outside of defining their data and altering business logic from within a route. If the place where business logic is executed is commingled with how data-stores are manipulated, you're going to have a bad time. Likewise if the place business logic is executed is commingled with the presentation of it to customers, you're going to have a bad time.
Python does not have a culture of dependency injection because it's so easy to import antigravity and fly away. This makes writing tests hard and promotes spaghetti code. Lack of dependency injection (which means violating scoping) is the entropic force that makes codebases miserable as time increases.
Additionally, you will have to think hard about state. If you can't restart a process trivially, or balance traffic to a different machine trivially, you are going to make your operational people's lives hard. State belongs in state storage. Put it in an RDBMS, put it in redis, put it in memcached, put it in anything but a python processes memory. This means that any two requests should be able to be sent to any two machines. This is a deeply important property for scaling.
Lastly, if you do not have good answers for observability, in terms of time series data, log data, exception data, and event data (for observability only), you will have a bad time. These are generally the things it is ok to violate scope to use.

One way to do this is by writing tests for your React components. Tools like Jest and Enzyme make it easy to test your component's behavior, rendering output, and state changes. By writing tests for your components, you can ensure that they behave as expected and prevent issues before they reach production.

react-testing-library
🐐 Simple and complete React DOM testing utilities that encourage good testing practices.
React Testing Library: This library provides simple and complete React DOM testing utilities that encourage good testing practices. It helps you write tests that are more focused on the behavior of your components rather than the implementation details. https://github.com/testing-library/react-testing-library

Project mention: Simplify Your Mock Data Creation in Tests with @lifeiscontent/to-mocked | dev.to | 2023-05-23
The added benefit of using toMocked is the immediate feedback it provides when application code changes and tests break. It shows how the expectations have changed, making it significantly easier to maintain and update your test suite. Especially when you're using testing frameworks like Vitest, toMocked integrates seamlessly, easing the writing of tests.

Kotest
Powerful, elegant and flexible test framework for Kotlin with additional assertions, property testing and data driven testing
Project mention: Best practices for Unit Testing Android Apps with Mockk, Kotest and others | dev.to | 2023-05-10As a matter of fact, in the previous examples, we have shifted a bit away from the TDD standards in the meaning that we test not only the operability of our code, but rather check if the code runs according to certain specifications (Given/When/Then). These specifications are our tests, and the syntactic sugar in the form of the possibility to give clear names to the tests using DisplayName and the grouping of the tests by a set of similar attributes helps us clearly formulate these specifications. There is an entire family of frameworks in different languages that allow us to create such specifications: for Java it is Spock, for Ruby—RSpec, and for Kotlin—Spek and Kotest frameworks. Below, I will go into more detail about them.
