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 consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware. The introduction of high-level programming languages in 1958 allowed for more human-readable instructions, making software development easier and more portable across different computer architectures. Software in a programming language is run through a compiler or interpreter to execute on the architecture's hardware. Over time, software has become complex, owing to developments in networking, operating systems, and databases. Software can generally be categorized into two main types: # operating systems, which manage hardware resources and provide services for applications # application software, which performs specific tasks for users The rise of cloud ...
