ACTUALITY OF CONDUCTING MODULAR TESTING IN SOFTWARE DEVELOPMENT

The testing process in creating software, as a separate stage, has its own life cycle. The testing lifecycle is part of the entire software cycle, and they must be synchronized with each other. Designing and developing testing in creating new software systems is a complex and time consuming task. The work of any software system is organized as a set of modules that can perform various functions. To ensure the correct operation of the system as a whole, you must first test each software module separately. In case of defects, this procedure will make it easier to identify the problem in the modules and completely eliminate the relevant shortcomings. Testing all modules separately is called modular testing. The article examines the main aspects of modular testing. The software life cycle is considered and the stages of the computer program development cycle are graphically presented. It is investigated that one of the most important stages is the stage software testing. The main definitions concept of "testing" are analyzed in detail and the main types of testing process are listed. It is established that modular testing is one of the most important types of testing. Modular testing is considered to be the simplest step in testing the entire system because the modules to be tested are usually small in size. When using this method, the complexity of creating test cases increases. To put the whole system into operation, you need to set the values of the test variables correctly, and to bring part of the real system to the required state, you need to run the whole scenario. However, modular testing is associated with significant problems, which are explored in the article. The main tasks and approaches to modular testing are evaluated. The article thoroughly reveals the characteristics of modular testing as a method of structural testing.
