String Calculator TDD

String Calculator TDD

Inspiration

Test Driven Development or TDD is something I was hearing a lot but didn't fully understand.

This little project is my way of exploring and learning it's fundamentals.

What it does

StringCalculatorTDD is a project created for TDD beginners as a solution for TDD Kata 1 - String Calculator.

Prerequisites

Before you begin, ensure you have met the following requirements:

  • You have installed the latest version of java, testng, maven

Exploring StringCalculatorTDD

To explore StringCalculatorTDD, follow these steps:

git clone https://github.com/2kabhishek/StringCalculatorTDD
cd StringCalculatorTDD
code . # Or any other of your favorite editor

Using StringCalculatorTDD

After cloning the project one good way to learn from it would be using git history.

Just do a git log and look at the changes, you can go through the entire process of TDD one step at a time.

How it was built

StringCalculatorTDD was built using Java and TestNG, the IDE used was Eclipse.

Challenges faced

Wrapping my head around the laws of TDD, which are:

  • You are not allowed to write any production code unless it is to make a failing unit test pass.
  • You are not allowed to write any more of a unit test than is sufficient to fail.
  • You are not allowed to write any more production code than is sufficient to pass one failing test.

What I learned

I learned why TDD is used and how it helps us in producing, bug free maintainable code.

The cycle of TDD is somewhat as such:

  • Write a failing unit test
  • Write code to pass the test
  • Refactor if necessary

I also learned about TestNG, which is a more feature rich equivalent of JUnit.

What's next

Probably use TDD in more of my future projects.
