Unit testing is a method of software testing in which the smallest parts (which we call units) of the software application are tested.

Simply put, “unit testing is a test in which the program is broken into pieces, and each piece is tested closely.”

The main objective of this testing is to mak

e sure that the source code of each unit of the software is correct and can be used.

Earlier adhoc tools were used to test units, but nowadays frameworks (Java Framework, .Net Framework and PHP Framework etc.) are used to test units.

Unit tests are written and performed by developers and the WHITE BOX TESTING method is used to do this.

The thing to remember here is that ”

unit testing takes too much time and requires a lot of patience”.

This testing is very effective as most defects are identified by its use.

Generally unit testing is done after integration testing.

Advantage of unit testing in hindi: –
Unit testing has the following advantages: –
1: – Through this testing, we find defects and bugs in the software only in the early stages, later it becomes very difficult to find defects and bugs.

2: -This testing makes the coding process more effective and agile (agile) so that we can add more and more features to the software.

3: -When we do unit testing, we need less manual testing. Anyway, manual testing is very boring and expensive.

4: – Through this testing, we can improve the design of the software without breaking it.

5: -When we detect bugs in advance, it saves our time and cost.

6: -This increases the efficiency of testing code and it becomes easy to maintain.

7: – One advantage of this testing is that it provides us with the updated documentation of the software.
