Using TDD with SOLID Principles

When I first started programming, I instantly got addicted to it. I felt so excited about the thought of coming up with a solution to a problem using programs and my own imagination. Back in school, there was a time when the instructor gave us the task of solving some simple algebraic challenges using Turbo-C. I had goosebumps and felt very excited as I quickly realized I could just write programs to solve these types of challenges repeatedly. Write the program once, pass different arguments, and get different results. I loved it. I remember a challenge to compute the height of a bridge if someone is standing on it, drops a ball, and hears a sound after several seconds. Easy! Now, I can just use my program to compute the height of the bridge for me repeatedly. Now, I don’t have to keep remembering that the Earth’s gravitational acceleration is at around 9.8 m/s2 – I can just declare it in the program! I learned that in programming...
