A functional specification (also, functional spec, specs, functional specifications document (FSD), functional requirements specification) in systems engineering and software development is a document that specifies the functions that a system or component must perform (often part of a requirements specification) (ISO/IEC/IEEE 24765-2010).
Specification by example (SBE) is a collaborative approach to defining requirements and business-oriented functional tests for software products based on capturing and illustrating requirements using realistic examples instead of abstract statements. It is applied in the context of agile software development methods, in particular behavior ...
v. t. e. 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 ...
Test cases are built around specifications and requirements, i.e., what the application is supposed to do. It uses external descriptions of the software, including specifications, requirements, and designs to derive test cases. These tests can be functional or non-functional, though usually functional. Specification-based testing may be ...
Note that this is very different from functional testing, which attempts to validate that the circuit under test functions according to its functional specification. This is closely related to functional verification problem of determining if the circuit specified by the netlist meets the functional specifications, assuming it is built correctly.
A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service. [ 1 ] A specification is often a type of technical standard. There are different types of technical or engineering specifications (specs), and the term is used differently in different technical contexts.
Software verification and validation. In software project management, software testing, and software engineering, verification and validation is the process of checking that a software engineer system meets specifications and requirements so that it fulfills its intended purpose. It may also be referred to as software quality control.
Functional verification is the task of verifying that the logic design conforms to specification. [1] Functional verification attempts to answer the question "Does this proposed design do what is intended?" [2] This is complex and takes the majority of time and effort (up to 70% of design and development time) [1] in most large electronic ...
