Intro:
This article is my first blog post on Medium.
I’ve come to Flutter recently and this transition makes me learn a lot these days. To better summarise the topic, the idea of this article was born.

“Senpai, why unit testing is important?”

When developers compile, run, debug, what do they do?

They expect to see if their program behaves as expected. And with unit tests, they can do it automatically.

The main idea of unit testing is to take the system under control and cover all components of software with tests to get all benefits. Otherwise, it would be a waste of time.
