Survey and identify current and most widely used Software
Testing Tools

Provide comparison study between 9 software testing tools

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

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)

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

Identifying testing tools used in Web Development
environment

Study and compare few tools that are used for Functional and
Non-Functional testing


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.
Thank You !!!
