Automating ADC Data Collection.This article describes an automated data collection system for analog-to-digital converters (ADCs). It discusses the advantages of automating data collection as well as a detailed description of the hardware and software. It goes on to explain the operation of the system and give some data examples....   Read Article.

Although developers have been unit testing their code for years, it was typically performed after the code was designed and written. As a great number of developers can attest, writing tests after the fact is difficult to do and often gets omitted when time runs out. Test-driven development (TDD) attempts to resolve this problem and produce higher quality,...   Read Article.

Testing applications on Pocket PCs requires a special strategy and plan. It’s different from testing normal client/server or Web-based application. Testing applications for Pocket PCs is like a mixture of strategies applied for testing client/server and Web-based applications....   Read Article.

theory of fault-based program testing is defined and explained. Testing is fault-based when it seeks to demonstrate that prescribed faults are not in a program. It is assumed that a program can only be incorrect in a limited fashion specified by associating alternate expressions with program expressions. Classes of alternate expressions can be infinite....   Read Article.

The purpose of this paper is to describe general data warehouse structure and background, as well as specific situations encountered during the testing effort for our project. Our project was to test a data warehouse and data mart for a large research department of a pharmaceutical manufacturing company. This was a pilot project and our efforts, if...   Read Article.

I've used lots of methods to transform data between databases and object code. From hand-coded SQL to JDO to EJB. I've never found a method I liked particularly well. This distaste has become especially acute since adopting test-driven development (TDD) as a guiding philosophy. Unit-testing should have as few barriers as possible. For relational...   Read Article.

This document has been created as a guide to help testing professionals select, understand and implement functional test tools in their organisation. Due to the large number of test automation tools available I have followed the 80/20 rule and selected the most popular as a base for this document. However where necessary other products including, Test...   Read Article.

Organisational Approaches for Testing This paper describes three organisational approaches for unit testing: top down, bottom up and isolation. The organisational approach is a key element of unit test strategy and planning; selection of an inappropriate approach can have a significant impact on the cost of unit testing and software maintenance....   Read Article.

This is a very important question to consider and, unfortunately, it has been my experience that this is the one question that the practitioners of QA often fail to even ask, much less attempt to answer. In short, a discipline generally tries to look for and exploit regularities in the area of its expertise. We use our disciplines to develop theories...   Read Article.

Like most concepts to be defined, in any attempts to define Quality Assurance (QA), it pays to consider that in light of what Quality Assurance does. A common thought is that Quality Assurance is there to either "fix the defects" or "prevent the defects". Those statements are true, as far as they go. However, QA does a lot more than just these two statements....   Read Article.

Testing information systems is a major concern for many organisations. It is often perceived as costly, time consuming, boring to do, and difficult to manage. In some organisations testing had become another word for contingency. Testers are sometimes blamed for having found faults which cause the application or system not to be deployed according to...   Read Article.

This paper illustrates how event/use case modelling can be used to identify, define and access requirements patterns. Event/use case partitioning is widely used as a way of breaking a system into manageable, business-related chunks. Each event/use case is then the subject of detailed analysis, design and implementation. This paper illustrates how event/use...   Read Article.

In this paper, we discuss the subject of software-based memory testing. By that we mean the testing of memory chips that are already installed in a final system. Such tests routinely occur as part of the hardware diagnostics that are executed shortly after power-on or reset. Memory tests need to be constructed carefully, so that they: (a) require as...   Read Article.
