You might want to know what errors can go unnoticed after the intensive application of static testing technologies, typical for the rapid method of testing. The answer is very simple: hidden errors. Hidden errors are errors that exist, but are not detected. Averagely, programs reaching end-users contain from 0.2 to 20 hidden errors per thousand delivered code instructions KSDI. In the event that you intensively apply static testing technologies in the development of the project, at the beginning of dynamic testing the number of hidden errors should decrease by 65-80%. The remaining 20-35% of hidden errors should be detected during unit testing, integration testing, system testing, acceptance testing and maintenance.
Dynamic testing finds errors that were committed during the process of determining the TOR requirements, the draft design, implementation engineering and coding requirements development.
Another, sometimes overlooked source of hidden errors is the reusable software. Possible types of errors include: logical errors, simple typos, data organization errors, errors affecting efficiency, usability errors, database query errors, file access errors, interface errors, load management errors, missing functions, erroneous algorithms, data exchange problems, defects in test scenarios, incorrect calculation of test results, and many others. Put it squarely, a consistent accumulation of errors that are still hidden at the time of the onset of dynamic testing occurs at all previous design stages. Due to the application of the rapid testing technique, which allows you to quickly identify and correct most of the hidden errors, you can save time and significantly reduce labor effort.
QA services are provided to make it possible for software developers to avoid making errors during the production process. Reputed specialists advise their clients on effective and efficient way of making mobile, web and desktop apps.
During TOR development and draft design, functional requirements are combined with non-functional ones. Examples of nonfunctional requirements can be the product delivery schedule, the set of installation kit, the requirements for populating database tables, the time characteristics of the algorithm, the human factor, the requirements for the supported configurations, the communication infrastructure, the security requirements, reliability, etc. Most of these requirements are developed on the basis of programming standards or style guides that operate in a specific organization.
