CSS Variables — What You Need to Know 🎨

CSS variables are more accurately described as custom properties.

They are useful in preventing DRY — Don’t Repeat Yourself code.

With the ability to change a property once and have that change made all over your style sheet is magical ❗️

Explicit Dependencies Principle ✨

Classes should be honest about what they need to be created. 🗣

Methods and classes should explicitly require any collaborating objects they need { typically through method parameters or constructor parameters } in order to function correctly. ✅

Mocking objects with Moq and XUnit in .NET Core 👾

This article explains the step by step process that needed to Moq an object in .NET Core ⚜️

Mocking objects comes in handy when unit testing data store, where a Database can be mocked so that no data is added or modified in Database while unit testing source code. ♻️

GIGO ♻️

GIGO is a computer science acronym that implies bad input will result in bad output, which stands for :

Garbage in 🗑
Garbage Out 🚮

🔸🔹🔸🔹

Because computers operate using strict logic, invalid input may produce unrecognizable output, or "garbage."

For example, if a program asks for an integer and you enter a string, you may get an unexpected result. ❌

Good programming practice dictates that ✅ :

"Functions should check for valid input before processing it."

A well-written program will avoid producing garbage by not accepting it in the first place.☝🏻

Requiring valid input also helps programs avoid errors that can cause crashes and other erratic behavior. ⚡️

Why you should join .NET Core and ASP.NET Core train ❓🚀

• .NET Core is a cross-platform version of .NET, that supports almost all that .NET supported. 🖥

🔸🔹🔸

• .NET Core and ASP.NET Core are FREE and Open Source but also they are supported by Microsoft. 💸

🔹🔸🔹

• ASP.NET Core is cross-platform web framework built on top of .NET Core.

It is built from scratch, however, a lot of old concepts and patterns are still the same. ✅

🔸🔹🔸

• Both, ASP.NET Core and .NET Core are faster and easier to work with, than their predecessors. 💨

🔹🔸🔹

• Node. is fast – over 400 000 requests per second.

• ASP.NET Core is blazing fast❗️– ASP.NET Core (on Linux ! ) itself can handle over 2 Million requests per second.

• ASP.NET Core MVC can handle over 1 million requests per second ❕

What is Unit Testing & Why You Need to Lean It ⁉️

Unit testing is the practice of writing code to test your code and then run those tests in an automated fashion. ✅

🔹🔸🔹🔸

Here is an example. 👨🏻‍💻

Imagine you have this function somewhere in your code.
It’s a basic calculate function that takes an input and depending on some conditions, it returns different values.

public float CalculateTax(int input) 
{
    if (x) return ...;
    if (y) return ...;
    return ...;
}

If you want to test this function manually :

1️⃣ You have to run your application
2️⃣ Perhaps you have to login
3️⃣ Maybe do a few clicks here
4️⃣ There to get to a page where this function is used.
5️⃣ You have to fill out a form
6️⃣ Submit it
7️⃣ Verify if this function returned the right result.

And then you have to repeat all these steps, each time using different values in your form. 🤦🏻‍♂️

🔸🔹🔸🔹

Manual testing is expensive 💸

As you can see, this is very time-consuming. ⌛️

This workflow to test this function may take several minutes every time❗️

Now to make matters worse, this is not the only function in your application. 🌍

In a real application, you have tens or hundreds of functions like this ❗️

As your application grows in size and complexity, the time required to manually test all the different bits and pieces increases exponentially. ⏱

So, that’s why we use Automated Testing. ♻️

MVC TempData – Peek vs Keep 🤙🏻

Most of the MVC developer knows that TempData is used to preserve data for a single request but reality is that TempData can pass data for next request also. 🤷🏻‍♂️

In this article we will discuss how to persist data with TempData using Keep and Peek method.

As well we will also see the difference between Keep and Peek method. 🤔
