WebContext. Performance testing is a challenging task mainly due to the lack of test oracles, i.e. mechanisms to decide whether the performance of a program is acceptable or not because of a bug. Metamorphic testing enables the gener-ation of test cases in the absence of an oracle by exploiting the so–called metamorphic relations between the inputs WebNov 24, 2024 · Test an implementation of the trigonometric function sin (x). More relations can be defined this way. Note: When using this technique to test a basic property of a function or a system, as in the case of the sine function, some texts call it property-based testing. The idea is similar to metamorphic tests.
