Why the first instruction we learn to program should be the last to use.
Nobody uses GOTO instruction anymore and few programming languages still support it.
Next evolution step will be removing most IF statements
IFs/Cases and Switches are GOTOs disguised as structured flow.
Our tool will be Object Oriented Programming principles.
Incomplete objects cause lots of issues.
Any linter can warn this (possible) situation.
Always create complete objects. Make their essence immutable to endure through time. Every object needs its essence to be a valid one since inception.
Writing a class without its contract would be similar to producing an engineering component (electrical circuit, VLSI (Very Large Scale Integration)…
In this serie we will see several symptoms and situations that make us doubt the quality of our developments.
We will present possible solutions.
Most of these smells are just clues of something that might be wrong. They are not rigid rules.
If we ask a domain expert to describe an entity he/she would hardly tell it is ‘a bunch of attributes’.
1) Find Responsibilities.
2) Protect your attributes.
3) Hide implementations.
Detection can be automated with sophisticated linters ignoring setters and getters and counting real behavior methods.
Since this is a “feature” in some languages it would be hard to test. We can set programming policies or choose more strict languages.
We should detect ! !! usages in non-boolean objects and warn our programmers.
We should be very strict and keep booleans…
Getters coincide in certain scenarios with a true responsibility. It will be reasonable for a window to return its color, and it may accidentally store it as color. So a color() method returning the attribute color might be a good solution.
Most linters can warn us if they detect anemic models with getters and setters.
Getters and Setters are a poorly established…
Try to avoid repetitive tasks.
Use scripts, programming, RPA, or anything suitable for you.
But never automate until you master the tasks.
This is procrastination monkey disguised! 🙈
Put auto meetings to timebox your tasks.
This is especially important if your calendar is public and other people can book you meetings.
This way you can rest between meetings.
Plan but don’t over plan or micromanage yourself.
The calendar is at your service. Not the way around.
Don’t have multiple ToDos, lists, Trellos, Kanbans, bookmarks.
Use a single one. The way Marie Kondo manages her mess.
Sometimes you need to run…
1. Remove Middle man.
Same as its opposite smell, We can detect this small using parsing trees.
This is exactly the opposite to Message Chain. We make explicit the message chain.
Whenever I have to think to understand what the code is doing, I ask myself if I can refactor the code to make that understanding more immediately apparent.
This article is part of the CodeSmell Series.
Nice article and nice explanation of TDD
But it has a severe misconception since the title
TDD has nothing to do with testing.
TDD is about developing. It is a software developing technique.
Testing is another activity
