Quality Assurance Company: What Testing Is And Where Did It Come From
To begin with, we need to know what is defined as software testing to better understand what we are talking about.
Software testing is a process that focuses on verification of a computer program and accompanying documents for the purpose of identifying defects and enhancing the quality of the product.
For decades, as software development lifecycle models evolved, there were quite different ways of looking at testing and quality assurance issues. There are several “ages of testing”.
In the 1950s and 60s, testing was highly formalized and carried out apart from software production process.
Nowadays, a quality assurance company runs testing during the development cycle since it is an integral part of this manufacturing process.
In fact, testing was rather a method of debugging. There existed a concept of so-called exhaustive testing that was aimed at covering all the possible combinations of input values for the application being tested. However, it soon became apparent that thorough testing was not possible because this approach did not help to find flaws in the documentation.
Improper software testing services can cause many problems and be less efficient but more costly than the results they generate. For this reason, you are recommended to turn to reputed QA providers.
Task: Imagine that your software app is capable of determining the side lengths of a triangle only by three input numbers. Suppose that your program is run in a certain isolated ideal environment and all you need to do is just to check if it works correctly with three 8-byte integer numbers. You should use automation so that the computer can run 100 tests per second. How long will it take to conduct all the checks?
But what do you think about preparing test statistics for this kind of verification? (These are necessary to find out whether the program functions correctly or not in every single case).
In the 70s, two fundamental testing ideas were born. At first, testing was considered as the process through which it was possible to verify the performance of the application under certain desired conditions (positive testing), and then, vice versa: as the process that helped to prove that the software did not work under certain desired conditions. This inner contradiction has not only survived in length of time but also has been fairly acknowledged by many authors as the two complementary goals of software testing.
Best software testing companies carry out both positive and negative testing as only when these approaches are used together it is possible to make the product more reliable and stable.
