In software development, functional testing is a form of software system testing that verifies whether software matches its design. Generally, functional testing is black-box meaning the internal program structure is ignored (unlike for white-box testing). [1] Functional testing can evaluate compliance to functional requirements. [2]
In the case of automated tools, the process that generates the build will often initiate the testing. [citation needed] Smoke tests can be functional tests or unit tests. Functional tests exercise the complete program with various inputs. Unit tests exercise individual functions, subroutines, or object methods. Functional tests may comprise a ...
Test development: test procedures, test scenarios, test cases, test datasets, test scripts to use in testing software. Test execution: testers execute the software based on the plans and test documents then report any errors found to the development team. This part could be complex when running tests with a lack of programming knowledge.
Functional test; Non functional test (performance, stress test) The aim of software dynamic verification is to find the errors introduced by an activity (for example, having a medical software to analyze bio-chemical data); or by the repetitive performance of one or more activities (such as a stress test for a web server, i.e. check if the ...
System testing can detect defects in the system as a whole. [citation needed] [1] System testing can verify the design, the behavior and even the believed expectations of the customer. It is also intended to test up to and beyond the bounds of specified software and hardware requirements. [citation needed]
Non-functional testing is testing software for its non-functional requirements: the way a system operates, rather than specific behaviors of that system. This is in contrast to functional testing , which tests against functional requirements that describe the functions of a system and its components.
Black-box testing, sometimes referred to as specification-based testing, [1] is a method of software testing that examines the functionality of an application without peering into its internal structures or workings. This method of test can be applied virtually to every level of software testing: unit, integration, system and acceptance.
For testing functional requirements (functional testing), Continuous Testing often involves unit tests, API testing, integration testing, and system testing. For testing non-functional requirements (non-functional testing - to determine if the application meets expectations around performance, security, compliance, etc.), it involves practices ...
