Falsifiability (or refutability) is a deductive standard of evaluation of scientific theories and hypotheses, introduced by the philosopher of science Karl Popper in his book The Logic of Scientific Discovery (1934). [B] A theory or hypothesis is falsifiable if it can be logically contradicted by an empirical test.
Testability is a primary aspect of science [1] and the scientific method. There are two components to testability: Falsifiability or defeasibility, which means that counterexamples to the hypothesis are logically possible. The practical feasibility of observing a reproducible series of such counterexamples if they do exist.
Testability is falsifiability; but there are degrees of testability: some theories are more testable, more exposed to refutation, than others; they take, as it were, greater risks. Confirming evidence should not count except when it is the result of a genuine test of the theory; and this means that it can be presented as a serious but ...
"Those among us who are unwilling to expose their ideas to the hazard of refutation do not take part in the game of science." — Karl Popper, The Logic of Scientific Discovery, p. 18 and p. 280 Thomas Kuhn argued that changes in scientists' views of reality not only contain subjective elements, but result from group dynamics, "revolutions" in ...
Imre Lakatos (UK: / ˈ l æ k ə t ɒ s /, [6] US: /-t oʊ s /; Hungarian: Lakatos Imre [ˈlɒkɒtoʃ ˈimrɛ]; 9 November 1922 – 2 February 1974) was a Hungarian philosopher of mathematics and science, known for his thesis of the fallibility of mathematics and its "methodology of proofs and refutations" in its pre-axiomatic stages of development, and also for introducing the concept of the ...
In logic, the law of excluded middle or the principle of excluded middle states that for every proposition, either this proposition or its negation is true. [1] [2] It is one of the three laws of thought, along with the law of noncontradiction, and the law of identity; however, no system of logic is built on just these laws, and none of these laws provides inference rules, such as modus ponens ...
Software testability is the degree to which a software artifact (e.g. a software system, module, requirement, or design document) supports testing in a given test context. If the testability of an artifact is high, then finding faults in the system (if any) by means of testing is easier. Formally, some systems are testable, and some are not.
By working with or as part of the NPI group, a test engineer ensures that a product is designed for both testability and manufacturability. In other words, to make sure that the product can be readily tested and built. The following are some general rules to ensure testability and manufacturability of a product:
