Google Test VS CppUTest

A versão inicial oferece suporte aos compiladores GNU Compiler Collection (GCC) e Clang e ao depurador GDB, LLDB e Google Test.

> Googletest ... declares a direct dependency on an older LTS release of absl

Looking at the build configuration code:

https://github.com/google/googletest/blob/main/CMakeLists.tx...

it seems like the dependence on Abseil is optional. i.e. you can use googltest on its own. I wouldn't recommend it (I kinda like doctest), but still.

Okay, time to start unit tests!!! We will use Unity Test Framework to do unit testing. It is one of widely used testing frameworks alongside with Check, Google Test etc. Just downloading source code, and putting it to the project folder is enough to make it work (that is also why it is portable).

Updating GCC (it happened to GoogleTest).

Roy's project uses Google Test, a C++ testing framework. His testing setup is similar to mine as we both keep source files in one directory and tests in another. The key difference is that I can run the tests using the Visual Studios run button. It was fairly easy to write the new tests as there were existing ones that I could reference to check the syntax!

The Google Test Documentation provides a primer for first-time users. The primer introduces some basic concepts and terminology, some of which I've been able to learn for this lab exercise.
