Dynamic testing (or dynamic analysis) is a term used in software engineering to describe the testing of the dynamic behavior of code. That is, dynamic analysis refers to the examination of the physical response from the system to variables that are not constant and change with time. In dynamic testing the software must actually be compiled and run. It involves working with the software, giving input values and checking if the output is as expected by executing specific test cases which can be done manually or with the use of an automated process. This is in contrast to static testing. Unit tests, integration tests, system tests and acceptance tests utilize dynamic testing. Usability tests involving a mock version made in paper or cardboard can be classified as static tests when taking into account that no program has been executed; or, as dynamic ones when considering the interaction between users and such mock version is effectively the most basic form of a prototype. The process and function of dynamic testing in software development, dynamic testing can be divided into unit testing, integration testing, system testing, acceptance testing and finally regression testing. Unit testing is a test that focuses on the correctness of the basic components of a software. Unit testing falls into the category of white-box testing. In the entire quality inspection system, unit testing needs to be completed by the product group, and then the software is handed over to the testing department. Integration testing is used to detect if the interfaces between the various units are properly connected during the integration process of the entire software. Testing a software system that has completed integration is called a system test, and the purpose of the test is to verify that the correctness and performance of the software system meet the requirements specified in its specifications. Testers should follow the established test plan. When testing the robustness and ease of use of the software, its input, output, and other dynamic operational behaviour should be compared to the software specifications.

Test (informatique)

vignette|Une programmeuse écrivant du code Java avec JUnit. En informatique, un test désigne une procédure de vérification partielle d'un système. Son objectif principal est d'identifier un nombre maximal de comportements problématiques du logiciel. Il permet ainsi, dès lors que les problèmes identifiés seront corrigés, d'en augmenter la qualité. D'une manière plus générale, le test désigne toutes les activités qui consistent à rechercher des informations quant à la qualité du système afin de permettre la prise de décisions.

Génie logiciel

Le génie logiciel, l'ingénierie logicielle ou l'ingénierie du logiciel (en software engineering) est une science de génie industriel qui étudie les méthodes de travail et les bonnes pratiques des ingénieurs qui développent des logiciels. Le génie logiciel s'intéresse en particulier aux procédures systématiques qui permettent d'arriver à ce que des logiciels de grande taille correspondent aux attentes du client, soient fiables, aient un coût d'entretien réduit et de bonnes performances tout en respectant les délais et les coûts de construction.
