Golang: Test-Driven Development(TDD) with Gin and MySQL
Unless you’re a Multimillion or a Billion dollar company, you probably don’t have a multimillion-dollar ad budget or professional Spinners. Your product needs to stand out on its own merits like App Quality, Performance, UI design, and User Experience. Most companies don't care about you, your product, and your vision or dreams. They don't give a damn about either their work helped you to get more business, revenue, users, or solving a problem. That's where CANOPAS comes into the picture. Whether you have a GREAT IDEA and you want to turn it into a DIGITAL PRODUCT. OR You need a team that can turn your NIGHTMARES into SWEET DREAMS again by improving your existing product. We help Entrepreneurs, startups, and small companies to bring their IDEA to LIFE by developing digital products for their business. We prefer using Agile and Scrum principles in project management for flexibility and rapid review cycles. We are not bound by technology. We will learn new technology if it significantly improves the performance of your app. We will solve your tech-related problems even though we are not THE EXPERT in it. And we've done it multiple times in the last 7 years. In the last seven years, we helped... A STARTUP to expand its users from 2500 to over 100000 by developing mobile apps for them. An enterprise client to redevelop their app that has 1M+ monthly paid users and 10M+ app downloads. Another enterprise client(5M+ app downloads in each store) to fix bugs and broken parts in the app and as a result, they had over 98% crash-free users. We offer a 100% MONEY BACK GUARANTEE if you don't like our work. No questions asked. Visit : https://canopas.com/blog
Test-Driven Development (TDD) is a software development technique in which You write tests for a piece of code before you write the code.
We write tests to define the desired behavior of the code and to ensure that the code meets those requirements.
The process of writing the tests first helps to ensure that the code is testable and that it meets the requirements of the user or client.
TDD helps to catch bugs early in the development process and to ensure that the code is maintainable and easy to understand.
It also promotes a test-first mindset and encourages the developer to think about the requirements and desired behavior of the code before writing it.
Throughout this blog, I’ll assume you’re familiar with the basics of Golang, like package importing and all.

How TDD works?
TDD is an iterative process that follows these steps.
Write a test for a small piece of functionality that doesn’t exist yet.
Run the test, which should fail because the code doesn’t exist yet.
Write the minimum amount of code necessary to make the test pass.
Rerun the test, which should now pass because the code has been written.
Refactor the code if necessary, making sure that all tests still pass.
Repeat the process for the next piece of functionality.
Let’s examine the above steps with a basic example of a sum function, which calculates the sum of two values.

The goal of TDD is to ensure that the code meets the requirements and behaves as expected by constantly testing the code during the development process.
This can help to catch bugs early on, improve code quality, and increase confidence in the software.
TDD is an iterative process that begins with writing a test, running it to confirm it fails, then writing the minimum amount of code to make the test pass and repeating this process until the feature is complete.
