Testing is the process of executing a program to find errors. To make our software perform well it should be error-free. If testing is done successfully it will remove all the errors from the software. 

Principles of Testing:-

(i) All the tests should meet the customer requirements.
(ii) To make our software testing should be performed by a third party.
(iii) Exhaustive testing is not possible. As we need the optimal amount of testing based on the risk assessment of the application. 
(iv) All the tests to be conducted should be planned before implementing it 
(v) It follows the Pareto rule(80/20 rule) which states that 80% of errors come from 20% of program components. 
(vi) Start testing with small parts and extend it to large parts. 

Types of Testing:-

1. Unit Testing

Unit testing is a method of testing individual units or components of a software application. It is typically done by developers and is used to ensure that the individual units of the software are working as intended. Unit tests are usually automated and are designed to test specific parts of the code, such as a particular function or method. Unit testing is done at the lowest level of the software development process, where individual units of code are tested in isolation.

The main advantages of unit testing include:

  1. It helps to identify bugs early in the development process, before they become more difficult and expensive to fix.
  2. It helps to ensure that changes to the code do not introduce new bugs.
  3. It makes the code more modular and easier to understand and maintain.
  4. It helps to improve the overall quality and reliability of the software.

Some popular frameworks and tools that are used for unit testing include JUnit, NUnit, and xUnit.

It’s important to keep in mind that unit testing is only one aspect of software testing and it should be used in combination with other types of testing such as integration testing, functional testing, and acceptance testing to ensure that the software meets the needs of its users.

It focuses on the smallest unit of software design. In this, we test an individual unit or group of interrelated units. It is often done by the programmer by using sample input and observing its corresponding outputs.
