Build a solid foundation in Unit Testing with this course

This course is all about writing effective unit tests using C# programming language and NUnit as a unit testing framework. Along the way, we will learn the concepts related to unit testing. Today unit testing is an absolutely required skill from any professional developer. Companies expect from developers to know how to write unit tests including all the most important topics such as mocking and test driven development (TDD in short). This course does not cover all the features of NUnit. This course is way more interesting.

Learning unit testing puts a powerful and very useful tool at your fingertips. Being familiar with unit testing you can write reliable and maintainable applications. It is very hard to lead a project which is not covered by unit tests.

Content and Overview

This course is primarily aimed at beginner developers. It provides solid theoretical base reinforced by tons of practical material.

We start with basics of unit testing. What is a unit test? What unit testing frameworks exist? How to run and debug unit tests. After getting acquainted with the basics, we will get to the NUnit framework. Here you’ll learn how to install the framework, set the runner. Then you’ll learn the basics of assertions and arrange-act-assert triplet. Other key features of NUnit are also covered:

Running tests from the console
Setup and teardown unit tests
Parameterized tests
Grouping and ignoring
Practicing writing of unit tests, it’s impossible to avoid applying mocks. I like the word “test double” more, in general. By the way, you’ll learn what the difference between the following notion is:

Test double
Fake
Dummy
Stub
Mock
You’ll learn how to write test doubles manually. You will also see a simple example of how to use a mocking framework for using mocks. I’ll use NSubstitute mocking framework for demonstration.

At the end of this section, you’ll get acquainted with two key approaches to unit testing, Classic or Detroit School and London School of unit testing.

You’ll separately learn the basic of test-driven development. It is hard to imagine a modern professional developer who doesn’t know about TDD, so you’ll learn what it is and what it is about. You’ll see the Red-Green-Refactor triplet in action.

I could not complete the course avoiding the best practices of writing unit tests. You’ll learn the basic concepts of the modern approach to unit testing called “pragmatic unit testing”. You’ll see what problems static classes and singletons bring regarding the unit testing. They make code harder to unit test. After that, you’ll learn the problem of extracting interfaces just for the sake of introducing shims for injecting dependencies.

You’ll know should you write unit tests for the trivial code. You’ll learn a lot more in the course.

So, in short, the course covers the following topics:

Basic notions of Unit Testing
NUnit and its basic features
Test Doubles including fakes, dummies, stubs, spies and mocks
How to write manual test doubles and how to use a mocking framework
TDD, red-green-refactor triplet
A great number of best practices of writing unit tests
In the end, we will recap what you have learned, and you will try to understand where you have to go further with the intention to master your skills.

How long is this course: The course is around 4 hours. All are video lectures. You will be able to download all the slides and code samples used in the course.

C/C++ vs. Rust: A developer’s perspective

C/C++ vs. Rust: A developer’s perspective

In this post, you'll see the difference between Rust and C/C++ in a developer’s perspective

C++ is an incredibly fast and efficient programming language. Its versatility knows no bounds and its maturity ensures support and reliability are second to none. Code developed in C++ is also extremely portable, all major operating systems support it. Many developers begin their coding journey with the language, and this is no coincidence. Being object-oriented means it does a very good job of teaching concepts like classes, inheritance, abstraction, encapsulation and polymorphism. Its concepts and syntax can be found in modern languages like C#, Java and Rust. It provides a great foundation that serves as a high speed on ramp to the more popular, easier to use and modern alternatives.

Now it’s not all rosy. C++ has a very steep learning curve and requires developers to apply best practices to the letter or risk ending up with unsafe and/or poor performing code. The small footprint of the standard library, while most times considered a benefit, also adds to the level of difficulty. This means successfully using C++ to create useful complex libraries and applications can be challenging. There is also very little offered in terms of memory management, developers must do this themselves. Novice programmers could end up with debugging nightmares as their lack of experience leads to memory corruption and other sticky situations. This last point has lead many companies to explore fast performing, safe and equally powerful alternatives to C++. For today’s Microsoft that means Rust.

The majority of vulnerabilities fixed and with a CVE [Common Vulnerabilities and Exposures] assigned are caused by developers inadvertently inserting memory corruption bugs into their C and C++ code - Gavin Thomas, Microsoft Security Response Center
Rust began as a personal project by a Mozilla employee named Graydon Hoare sometime in 2006. This ambitious project was in pre-release development for almost a decade, finally launching version 1.0 in May 2015. In what seems to be the blink of an eye it has stolen the hearts of hordes of developers going as far as being voted the most loved language four years straight since 2016 in the Stack Overflow Developer Survey.

The hard work has definitely paid off. The end result is very efficient language which is characteristically object oriented. The fact that it was designed to be syntactically similar to C++ makes it very easy to approach. But unlike the aforementioned it was also designed to be memory safe while also employing a form of memory management without the explicit use of garbage collection.

The ugly truth is software development is very much a trial and error endeavor. With that said Rust has gone above and beyond to help us debug our code. The compiler produces extremely intuitive and user friendly error messages along with great direct linking to relevant documentation to aid with troubleshooting. This means if the problem is not evident, most times the answer is a click away. I’ve found myself rarely having to fire up my browser to look for solutions outside of what the Rust compiler offers in terms of explanation and documentation.

Rust does not have a garbage collector but most times still allocates and release memory for you. It’s also designed to be memory safe, unlike C++ which very easily lets you get into trouble with dangling pointers and data races. In contrast Rust employs concepts which help you prevent and avoid such issues.

There are many other factors which have steered me away from C++ and onto Rust. But to be honest it has nothing to do with all the great stuff we’ve just explored. I came to Rust on a journey that began with WebAssembly. What started with me looking for a more efficient alternative to JavaScript for the web turned into figuring out just how powerful Rust turns out to be. From its seamless interop…

Automatically generate binding code between Rust, WebAssembly, and JavaScript APIs. Take advantage of libraries like web-sys that provide pre-packaged bindings for the entire web platform. – Rust website
To how fast and predictable its performance is. Everything in our lives evolves. Our smartphones, our cars, our home appliances, our own bodies. C++ while still incredibly powerful, fast and versatile can only take us so far. There is no harm in exploring alternatives, especially one as exceptional and with as much promise as Rust.
