William C. Hetzel
Dr. William C. Hetzel is an expert in the field of software testing. He compiled the papers from the 1972 Computer Program Test Methods Symposium, also known as the Chapel Hill Symposium, into the book ''Program Test Methods.'' The book, published in 1973, details the problems of software validation and testing. Hetzel and Dave Gelperin co-found the Software Quality Engineering consultancy firm in 1986. In 1988 they classified the phases and goals of software testing into the following stages: * Until 1956 – Debugging Oriented – Until 1956 it was the debugging oriented period, when testing was often associated to debugging: there was no clear difference between testing and debugging. * 1957–1978 – Demonstration Oriented – From 1957–1978 there was the demonstration oriented period where debugging and testing was distinguished now – in this period it was shown, that software satisfies the requirements. * 1979–1982 – Destruction Oriented – The time ...

TechWell Corporation
TechWell Corporation (formerly Software Quality Engineering, SQE), was founded in 1986 by Bill Hetzel and David Gelperin as a consulting company to help organizations improve their software testing practices and produce higher quality software. Company During the late 1980s, Hetzel and Gelperin developed a software testing methodology, the Software Test and Evaluation Process (STEP) and an accompanying training course called Systematic Software Testing. During the 1990s, more than 10,000 testers from all parts of the world took this course and learned the STEP approach for testing. Notably, SQE coined the term “Test Then Code” in 1987, many years before approaches like test-driven development (TDD). SQE launched its first industry conference, Applications of Software Measurement (ASM) in 1991, followed by Software Testing, Analysis and Review (STAR) conference in 1992 and EuroSTAR in 1993. In 1998, when the STAR conference in the United States had grown to attract more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Testing People
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
