Neurobiology: 2 hemispheres

As human beings, we have 2 hemispheres:

1. The first one is responsible for exploratory mechanisms, but is not particularly good at executing things precisely and immidiately. Especially this failure is obvious during mechanical operations.

⛴ Coupling and Cohesion

Intro

The story starts few weeks ago when on codereview my colleague asked me to inline class if possible. I, being a SOLID dev, was shocked: why would I increase coupling, break SRP, and thoughts like this.

🤔 Totally legal kind of comments in the code

So far I can be sure that the only type of comments in code is legal, needed…

Tests naming

I used to write test names on PHP like

public function testThatSomethingIsHappeningWhenSomeConditionIsSatisfied(): void {}

And it worked well for me all this time.

Testing an implementation and testing a state

Sometimes I want to test the implementation — like assert that some external calls are done, that some method is called no more than 1 time, or something similar. I usually use unit tests for that.

Make code reusable

Given:

I’ve got an abstract class, with a needed method, which I want to reuse

Wanted:

Reuse the method in the rest of the system in most appropriate way

Solution:

Using patterns for reducing complexity

There is a common opinion that OOP patterns reduce complexity of code and project in general.

To me it was sort of obvious, before I spoke to a frontend guy, who hates OOP and does some functional programming. He said that he hates all…

The biggest problem in the programming

The main problem in programming nowadays is code coupling.

Every pattern and practice is dedicated to reduce this coupling.

• TDD allows you write minimally coupled code from very beginning, which is the most…
