T-X
- Task
- In XP, a task describes a piece of functionality that can be implemented by a developer pair in a few hours.
- Test case
- The specification of a test; it includes the target object, inputs, expected outputs, as well as context and side conditions of that test run.
- Test driver
- A program that runs a series of tests automatically.
- Test first
- Other terms are test-first programming, test-first design, or test-driven development. A software development approach that specifies the result of a manageably small implementation step in an automated test case before the actual coding takes place.
- Test oracle
- A function or algorithm that uses the input data to create the expected output data, so that a test can use it as expected output data.
- Test suite
- A set of test cases jointly run and viewed.
- Thread
- Also called execution context or lightweight process. A sequential control flow within a program with its own stack and program counter. Several threads can run in parallel within a program, that is, within the same address space.
- Top-down
- An approach used, for example, for testing or design, where a hierarchical problem or system is initially viewed on the top hierarchical level to then be further decomposed. Opposite Bottom-up.
- UML
- Unified Modeling Language. A visual modeling language for object-oriented software models standardized by the Object Management Group (OMG).
- Unit test
- A type of test that, in contrast to a system test, refers to a single unit (method, class, component) of a system rather than to the overall system.
- Use case
- The definition of a behavior of the software product based on gradually described interactions between user and system.
- User story
- Informal description of a functional requirement or product property in XP. A user story serves as the basis for acceptance tests that formally check whether the product complies with the described function or property.
- Value semantics
- An object should be viewed as a value when its identity is determined by its invariable state.
- Waterfall
- The simplest sequential software process model, where the analysis, design, coding, and testing phases are done sequentially for the entire system.
- White-box test
- An implementation-based test, in contrast to a specification-based test;
See also Black-box test.
- XML
- Extended Markup Language. A family of technologies allowing one to define so-called markup languages (languages with a structure similar to HTML) and to create, exchange, and edit corresponding documents.
- XP
- Extreme Programming. An agile development process, the origin of test-first development, among other things.
