A Brief History of Software Testing

A Brief History of Software Testing

Since the advent of computers, software testing has been a necessary component of program development. Such testing ensures that applications meet quality and performance standards. For the testers themselves, it is not even easy in this field. But have you ever thought about the history of the origin of software testing and how everything began to develop rapidly after that? If you are interested in learning and delving into the world of software testing history, then we suggest you read this article. We will also reveal why professional testers choose courses from Test Pro and what is special about this platform. Well, have we intrigued you? Then we begin!


The main historical stages of software testing

1. Debugging-oriented era (1950s)

  • This stage was born when there was no difference between testing and debugging;
  • Attention to error correction during code analysis;
  • There was no clear concept of “software tester” or “software testing”.

2. Demonstration-oriented era (1957-1978)

  • The difference between debugging and testing has been developed;
  • Testing is conducted as a separate activity;
  • Testing aimed at verifying the fulfillment of software requirements.
  • “The more you test, the more likely you are to find a bug.”

3. Destruction-oriented era (1979-1982)

  • Cracking the code and searching for errors;
  • Glenford J. Myers introduced the separation of debugging from testing (1979);
  • The “destruction” approach failed; lack of defect prevention; the risk of never releasing the software due to constant bug-finding.

4. Evaluation-oriented era (1983-1987)

  • Special attention to evaluation and measurement of software quality;
  • Testing continued until an acceptable level of error detection was achieved, especially for large software.

5. Prevention-oriented era (1988-2000)

  • A new approach, where the main emphasis is on demonstrating conformity to specifications, identifying faults and preventing defects;
  • There are now 2 types of code: test and non-test (it was important that the tested code had fewer errors than the code that is difficult to test);
  • Identification of test methods became crucial and exploratory testing emerged for a deep understanding of software to detect bugs.

The peak of evolution in the history of software testing was in 2004. It was then that automated testing tools appeared, such as Selenium.

And of course, nowadays there are different types of testing, for example, unit testing, integration testing, acceptance testing, etc. We would also like to draw your attention to the fact that the current era is moving towards testing with the help of artificial intelligence (AI) tools. But will AI ever replace the software tester or not? Interesting question, isn’t it?

What Is QA Testing

Quality assurance testing, sometimes known as QA testing, is an important phase in the software development process. Effective QA testing uncovers mistakes and inconsistencies that may impact the real-world usage of the program under development. Testing assures product lifetime while saving businesses time and money when performed properly. Developers on a short budget may be […]

Who Is Tester?

In this article, we will identify the essential qualities of the role in IT and explain who the software tester is. To begin, a tester is responsible for understanding the software product, assessing the acceptance criteria, building test cases and documentation, running tests and producing clear, detailed reports based on test findings. Furthermore, the tester […]
