Black box techniques

by Alexandru Nicolescu
on April 28, 2014

In this article I’ll explain some of the black box testing techniques that I applied during the testing projects I was involved into: equivalence partitioning, boundary value analysis and state transitioning testing.  

What is black-box testing?

Black-box testing, also called behavioral testing, focuses on the functional requirements of the software. Black-box testing enables the software engineer to derive sets of input conditions that will fully exercise all functional requirements of a program. Black-box testing is not an alternative to white-box techniques. Rather, it is...

It is a non-production data, which is mainly used for analyzing and reporting, in order for management team to make important business decisions. Non-production data is represented  by data that is not used by a certain sector of a business, but is a necessary data for the entire business to grow and to adapt to the new conditions.

More and more complex applications are developed using web technologies. And since we are always on track with what's what in the testing industry, we came up with a series of articles that guide you through the entire web testing process. The software testing of the web applications, also known as web testing, is focusing on the applications that are accessed through a browser. The main issues are related to the functionality, usability, performance and security of the website.

Introduction in Python

on March 10, 2014

“Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated. Readability count…” The Zen of Python – PEP20  Python was the language we spoke at our previous Technical Workshop @Q backed by Cristin Iosif. Our colleague dedicated this subject three presentation sessions with the purpose to enlarge the programming portfolio used by the Q team. These sessions will cover three areas, as follows:

  1. Python overview, core concepts and...

You get yourself into a situation like: you have to delete a certain row from each group of rows, but it is not by a maximum value and not by a minimum value, but more like second to last.

Your table would look like this, and you would like to delete the second to last row, ordered by date, from each department id.

Client_id Department_id...

Cloud Computing

by Carmen Pascalache
on December 3, 2013

As a metaphor for the Internet, "the cloud" is a familiar cliché, but when combined with "computing," the meaning gets bigger and fuzzier. Some analysts and vendors define cloud computing narrowly as an updated version of utility computing: basically virtual servers available over the Internet. Others go very broad, arguing anything you consume outside the firewall is "in the cloud," including conventional outsourcing.

Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add...

Boundary value analysis and equivalence partitioning

by Alin Barbu
on February 23, 2013

1. Introduction Boundary value analysis and equivalence partitioning both are test case design strategies in black box testing. Equivalence Partitioning and Boundary value analysis are linked to each other and can be used together at all levels of testing. 2. Equivalence Partitioning Equivalence partitioning (also called Equivalence Class Partitioning) is a software testing technique that divides the input data of a software unit into partitions of equivalent data from which test cases can be derived. In principle, test cases are designed to cover each...
