Software testing history

All the following information has been taken from accepted and identified sources.
Please send me all interesting information about software testing, along with the source and time period ,and I will put it on this page.

Usage of the term "bug" to describe a defect has been a part of engineering jargon for many decades, perhaps even from the times of Tomas Edison. In software testing it always refers to September 9th, 1945, when the first real bug traced an error in the Harvard Mark II, an electromechanical computer. This bug was carefully removed and taped to the log book (see picture: Google: The First "Computer Bug" ). This history is usually connected with the name Grace Murray Hopper, who described this event in the computer log.

Let us start the history of testing from the 50s, when the first modern programming language was designed: FORTRAN, the "FORmula TRANslator", invented by John W. Backus, and the first FORTRAN compiler was delivered in April 1957.

The history of computers starts form Analytical Engine created in 1842 by Charles Babbage enlisted the help of Lady Ada Lovelace as a translator. Ada, called herself 'an Analyst'
Charles Babbage, (1791 – 1871) was an English mathematician, philosopher, inventor and mechanical engineer who originated the concept of a programmable computer [Wiki]

1950 - 1960     1960 - 1970      1970 - 1980     1980 - 1990      1990 - 2000     2000 - 2010

  1. 1953 Dr Edward Deming published: Management’s responsibility for the Use of Statistical Techniques in Industry. He outlined 14 quality principles in this book.
  2. 1954 - The first truly mass-produced computer IBM 650 was marketed.
  3. 1955 - Grace Hopper created Flow-matic, the first high-level language.
  4. 1955 the first computer user group, called SHARE was formed.
  5. Until 1957 it was the debugging oriented period, when there was no clear difference between testing and debugging.

  1. 1960 - Digital Equipment Corporation (DEC) marketed the PDP-1,considered the first commercial minicomputer
  2. 1960 - Block structure for better organization of code in the programs was introduced in Algol.
  3. January 1, 1961 Computer Programming Fundamentals,Mcgraw-hill Inc; 1 edition by Herbert Leeds and Jerry Weinberg, describes software testing.
  4. 1962 The first computer science departments established at Purdue and Stanford.
  5. 1962 Douglas Engelbart invented the computer mouse. (The keyboard was first invented and patented in 1868 by Christopher Latham Sholes.)
  6. 1963 Adam, Carl – wrote his dissertation with topic: Petri Nets.
  7. 1964 The American National Standards Institute (ANSI) officially adopted the ASCII (American Standard Code for Information Interchange) character code.
  8. 1966 Book:"Computer Programming Fundamentals" by Herbert D. Leeds and Gerald M. Weinberg
  9. 1967 Herm Schiller creates the first software code coverage monitor, called Memmap, at IBM Poughkeepsie. It supports 360/370 Assembler language. [Richard Bender] - the source of that credit made a mistake.

    Phillip Carroll came up with the MEMMAP idea while working for Bill Cammack, after previously working at Product Test Lab in Pok. He was working in PTL while System 360 was being developed and during that time he wrote a primitive OS for it before any hardware was available. (Testing had to be done on a 360 simulator that ran on a PTL 7090.) The little OS he wrote was used to run primitive hardware test programs written in assembler. (It was used in PTL and on the manufacturing floor in Poughkeepsie for years.)

    As a result of that work, he understood 360 hardware design at a very deep level. In particular, he was very familiar with hardware branch interrupt logic. Shortly after joining Cammack's shop in the DPD lab some years later, he came up with the idea of capturing an execution map by trapping branches and modified an IBM 360 assembler to trace code execution, using the branch map. Thus: MEMMAP. [Phillip Carroll Tucson AZ]

  12. 1969 The first automatic teller machine (ATM) was put in service.
  13. 1969 Definition of testing: "Testing shows the presence, not the absence of bugs " by Edsger Wybe Dijkstra (1930 -2002) Source: J.N. Buxton and B. Randell, eds, Software Engineering Techniques, April 1970, p. 16. Report on a conference sponsored by the NATO Science Committee, Rome, Italy, 27–31 October 1969
  14. 1969 Richard Bender and Earl Pottorff created the first static and dynamic analysis tools using data flow analysis for improved test coverage. It increases code based coverage by 25% over the statement and branch coverage criteria in Memmap. (search for article called "How Do You Know When You Are Done Testing" that addresses this.) Note: this work was given the first Outstanding Invention Award ever handed out by IBM for breakthroughs in software engineering.
