Today we are going to discuss about Unit testing. It is one of the fundamental levels of testing in software testing.

To learn unit testing and other levels of testing, you can join a software testing course in Pune. For now, let's see the concept in brief.

Introduction to Unit Testing

Definition:

Unit Testing is a level of software testing where singular units/segments of a software product are tested. The main aim is to approve that every unit of the software executes as planned.

A unit is the smallest testable piece of a software product or an application. It as a rule has one or a couple inputs and typically a solitary output.

Unit testing is carried out by making use of white box testing method.

It happens to be the starting level of testing and is carried out prior to integration testing.

Unit Testing is majority of the times performed by the developers themselves or their peers. In uncommon cases it might likewise be performed by autonomous software testers.

Benefits of Unit Testing:

The expense of resolving a defect recognized amid unit testing is lesser in contrast with that of defects identified at more higher levels of testing.

Unit testing builds trust in changing/looking after code. In the event that great unit tests are composed and on the off chance that they are run each time any code is modified, we will have the capacity to quickly get any defects induced due to the change

Debugging becomes simple. At the point when a test falls flat, just the most recent changes should be debugged.

Codes are more reusable. So as to make unit testing conceivable, codes should be in modular format. This implies codes are simpler to reuse.

Codes are more reliable. Why? I think there is no compelling reason to disclose this to a normal individual.

Development happens in a speedier manner. How? On the off chance that you don't have unit testing set up, you compose your code and play out that fuzzy 'developer test' (You set some breakpoints, fire up the GUI, give a couple inputs that ideally hit your code and trust that you are good to go.) If you have unit testing set up, you write the test, write the code and run the test
