Overview

Survey and identify current and most widely used Software

Testing Tools

Provide comparison study between 9 software testing tools

Goal

It is a process of:

◦ Verifying and Validating the software

◦ Making sure the software meets the business and technical

requirements

◦ Making sure the software works as expected without bugs

Testing can be done at different points in the development

process, but mostly performed after the programming is

completed

Software Testing

Black Box Testing: Testing without any knowledge of the internal

implementation

White Box Testing: Testing with the knowledge of and access to the

code, data structure and the algorithms

Grey Box Testing: Creating test cases with access to code and the data

structure, but testing as a user(black box testing)

Testing Methods

Unit Testing: Testing only the functionality of a particular

module or a specific section of the code

Integration Testing: Testing to find the defects in the interfaces

and interaction between integrated components

Regression Testing: Finding defects after a major code change,

to make sure what used to work before, hasn’t stopped working

Acceptance Testing: Performed by the customer in his environment

before accepting the software

Certain tools are not free and the free versions do not have all

features

Certain testing need to be done in a network or against a Web

server that you need to have full access to

I don’t have a sample project to test in different platforms.
