In the article “Quality Assurance. Quality control. Testing ”, it was proposed, based on the survey results, the definition of the concept of software testing:
Software Testing is one of the techniques of quality control and includes activity on job scheduling (Test Management), test design (Test Design), Test Execution, and Test Analysis.
I bring to your attention a study on the " necessary and sufficient conditions for testing ."
Consider the definitions of the required concepts:
Let's start with the necessary conditions. It is obvious that testing is not possible without a test object, hence we get the first condition: the presence of a test object available for testing. Further, in order for the testing to take place, we need a performer, which means that the second necessary condition is the presence of the performer , and they can be a person or a machine, or a combination of person + machine.
We proceed to the definition of sufficient conditions. Since not every action performed on a program, in order to obtain the expected behavior, is testing, the question arose that the goal itself, namely: testing, is one of the sufficient conditions. Taking as a basis the fact that having a test plan directly indicates the intention to test, we find that the test plan is one of the sufficient conditions.
During testing, a person or a machine will have to perform some actions to check the real and expected behavior of the program. Hence, the presence of test cases / tests is also a sufficient condition.
To confirm that testing has occurred, we need a report on the results. As the saying goes: “there is a report - there is testing, there is no report - there is no testing”. So, to confirm that testing took place, a report on the results of testing should be generated.
Total we have the following necessary and sufficient conditions for testing:
Prerequisites :
Let us return to the proposed definition of software testing and consider whether it does not contradict the above conditions. As far as can be judged, everything converges: the presence of a test plan speaks about activities in the field of planning, test cases and tests — about the design, the contractor — about the execution of tests, the presence of a report indicates an analysis of the results obtained.
