Integrate UT in a CLI Pipeline

[Gallasko]

We need to integrate unit testing (UT) into the Continuous Integration (CI) pipeline for the game engine project. The goal is to ensure that every commit or pull request automatically runs the unit tests to verify the stability of the codebase.

Task Breakdown:

Set Up Unit Testing Framework:

Integrate unit testing framework of the C++ project. (Google Test)

Modify CI Pipeline:

Create a CLI pipeline to include a step that automatically runs the unit tests, using a service like GitHub Actions.
Ensure that the CI pipeline triggers on every push and pull request.
Test Result Integration:

Set up the pipeline to display test results in the GitHub pull request UI.
Ensure that the pipeline fails if any unit test fails, preventing untested or unstable code from being merged.
Documentation:

Add a section to the README that explains how contributors can run unit tests locally.
Include details on how the unit tests are run automatically in the CI pipeline.
Skills Needed:

C++ and unit testing frameworks (Google Test, Catch2, etc.)
Familiarity with CLI tools and Continuous Integration (CI) pipelines (GitHub Actions, Travis CI, etc.)
Difficulty: Intermediate

Expected Outcome:

A fully integrated unit testing step in the CLI pipeline.
CI should automatically run unit tests on every push/pull request and provide feedback based on test results.
