Logical and Statistical Form of Root Cause Analyses

Analysis of root causes can be carried out on the stage of product development in order to determine the basic software bugs and their causes and to take all possible measures to prevent them. As we aspire to prevent bugs from the very beginning of product engineering, when the actual information about bugs...

What Can Be Done to Prevent Software Bugs?

Due to the fact that errors are the incorrect or missing effects of human actions, it would be possible to prevent the occurrence of such defects, if we could automatically detect and correct wrong people’s actions. Such preventive actions are called faults blocking because they help to freeze the...

What Is Coverage and Coverage-Based Testing?

The majority of generally accepted testing techniques, it doesn’t matter if it is functional testing (black-box testing) or structural testing (white-box testing), use different ways of test coverage as the criteria for stopping testing. The easiest way is completing different checklists, such as a...

What Is Usage-Based Statistical Testing?

Actual client usage of software may be considered as a form of usage-based testing. In the case if defects are detected by clients, some information about them can be reported to software vendors, and integrated fixes may be created and delivered to all the clients to avert such defects. Nevertheless,...

The Meaning of Functional Testing In Software Project. Part I

Functional testing examines the right handling of the external functions of software product, with the help of monitoring the program external behavior at the time of implementation. Software is treated as a black-box, with the external behavior monitored through its input and output. That is why it is...
