Magento 2 How to Run Unit Tests via Command Line

In this tutorial, we will talk about How to Run Unit Tests via Command Line in Command Line Series. As you know, from Magento 2, they add many commands in bin/magento. This topic might be difficult to understand but I will make it clear in this post. I will explain in more detail about How to Run Unit Tests via Command Line.

Let’s learn about Magento unit testing first.

What is Unit Testing in Magento 2?

Unit testing is a level of software testing where individual units/components of a software are tested. It is to validate that there is no problem with the performance of each unit of the software.

So why Unit Test?

Here are some benefits of unit testing:

Find the problems early
Quickly facilitate changes and identify faults caused by changes
Test code to identify what it is responsible for to create better design

How to Run Unit Tests via Command Line
