WHAT IS UNIT TESTING / JUNIT / MOCKITO

Unit testing is a concept where you test your code at the smallest level possible.

It is similar to how cars are tested. When you are developing different parts for a car, you have to test each part in isolation to verify whether it is working as expected or not. Once the test of that part runs clear, it is then integrated with the other components of the car to verify the integration.

The same is true for software code where we need to test out functionality at the unit/class/interface/method level to ensure that everything is working as intended.

JUnit is a unit testing framework that is widely used by Java programmers all over the world. It is one of the most capable testing frameworks which offers support and integration for a variety of other testing frameworks. It is currently presented in its fifth form, a form that has lots of improvements and support for the latest Java goodies.

Mockito is a mocking framework that allows us to flexibly extend our unit testing capabilities without the overhead of having to maintain a large mock.

TOP 3 BENEFITS OF LEARNING UNIT TESTING

1: High demand. Unit testing has become very popular with the addition of CI/CD tools and it has become a basic skill that a developer needs in order to perform his everyday duty.

2: A job requirement. "Unit testing" has become one of the most searched terms for hiring agencies when looking for new developers. Adding JUnit and Mockito skills to your CV will boost your chance of getting hired into your dream job.

3: Creates the best code. Testable code is a readable and maintainable code. Why not use unit testing skills to build reliable applications instead of average applications full of bugs?

FREQUENTLY ASKED QUESTIONS

Why do we need Mockito when we can use input data instead?

Not using Mockito or any other mocking framework will make your test dependent on the environment that it is run on (databases, environment variables, etc).

Second thing, we do not want to test the JDBC or other frameworks with which we connect different services, because they were tested and it does not bring any value to our development life-cycle.

Why bother unit testing when we have testers?

Well, testers are usually making what we call black-box testing, they cannot find all the edge-cases, they will just make sure that the requirements of the application are met when implementing.

So, a lot of cases remain untouched until the deployment of the application to the end-user.

How can I benefit from this course? 

You can benefit from this by completing it and then sharing it on your professional platforms and adding it to your LinkedIn certifications. This way, when recruiters search for "Mockito", "JUnit" and "unit testing" as keywords, your profile will show up and they will contact you.
