The name is a reference to a story in the book The Pragmatic Programmer in which a programmer would carry around a rubber duck and debug their code by forcing themselves to explain it, line by line, to the duck. [1] Many other terms exist for this technique, often involving different (usually) inanimate objects, or pets such as a dog or a cat.
System under test (SUT) refers to a system that is being tested for correct operation. According to ISTQB it is the test object. [1] [2] [3] From a unit testing perspective, the system under test represents all of the classes in a test that are not predefined pieces of code like stubs or even mocks. Each one of this can have its own ...
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
program in a given programming language. This is one measure of a programming language's ease of use. Since the program is meant as an introduction for people unfamiliar with the language, a more complex "Hello, World!" program may indicate that the programming language is less approachable. [19] For instance, the first publicly known "Hello ...
[1] [2] When used to determine if a computer program should be subjected to further, more fine-grained testing, a smoke test may be called a pretest [5] or an intake test. [1] Alternatively, it is a set of tests run on each new build of a product to verify that the build is testable before the build is released into the hands of the test team. [6]
[1] [2] For example, the happy path for a function validating credit card numbers would be where none of the validation rules raise an error, thus letting execution continue successfully to the end, generating a positive response. Process steps for a happy path are also used in the context of a use case. In contrast to the happy path, process ...
A test stub is a test double that provides static values to the software under test. A test stub provides canned answers to calls made during the test, usually not responding at all to anything outside what's programmed in for the test. [1] A stub may be coded by hand or generated via a tool.
It was founded in 1987 by four graduates of the California Institute of Technology [1] who planned to commercialize the parallel computing software tools they had been working on for the Caltech Cosmic Cube, [2] which was the first working hypercube computer built.
