UnitTest Framework Overview - Unittest Framework

What is Unit Test Framework Overview?

Unit testing is a software program testing method by using which individual units of source code, such as functions, techniques, and class are tested to determine whether they are fit for use. Intuitively, one can view a unit as the smallest testable part of an software. Unit assessments are quick code fragments created by way of programmers at some point of the development system. It forms the basis for component testing.

Unit testing can be done within the following ways –

Manual Testing Automated Testing

Executing the test cases manually without any tool support is known as manual testing.

Since test cases are executed by human resources so it is verytime consuming and tedious.


As test cases need to be executed manually so more testers are required in manual testing.


It is less reliable as tests may not be performed with precision each time because of human errors.


No programming can be done to write sophisticated tests which fetch hidden information.

Taking tool support and executing the test cases by using automation tool is known as automation testing.

Fast Automation runs test cases significantly faster than human resources.


Theinvestment over human resources is lessas test cases are executed by using automation tool.


Automation tests perform precisely same operation each time they are run andare more reliable.


Testerscan program sophisticated teststo bring out hidden information.

JUnit is a unit trying out framework for the Java programming language. JUnit has been important inside the development of test-driven development, and is one of a family of unit trying out frameworks collectively called xUnit that originated with JUnit. you can find out JUnit tutorial here

The Python unit testing framework, sometimes referred to as “PyUnit,” is a Python language version of JUnit advanced by Kent Beck and Erich Gamma. PyUnit forms part of the Python standard Library as of Python version 2.1.

Python unit testing framework supports test automation, sharing of setup and shutdown code for checks, aggregation of exams into collections, and independence of the tests from the reporting framework. The unittest module provides classes that make it clean to support those qualities for a set of tests.

This tutorial has been prepared for the beginners to assist them recognize the simple functionality of Python testing framework. After completing this tutorial you may locate yourself at a moderate level of expertise in the usage of Python testing framework from in which you can take your self to the next levels.

You should have reasonable expertise in software development the use of Python languageOur Python academic is a good place to begin learning Python. knowledge of basics of software testing is also desirable.

Environment Setup

The classes needed to write tests are to be determined in the 'unittest' module. if you are using older versions of Python (previous to Python 2.1), the module can be downloaded from http://pyunit.sourceforge.net/. however, unittest module is now a part of the usual Python distribution; hence it requires no separate installation.
