Struct fixt::Unpredictable [−][src]
represents an unpredictable curve
unpredictable curves seek to:
- disrupt ‘just so’ implementations of algorithms that lean too heavily on fragile assumptions
- have a high probability of generating common edge cases that developers fail to cover a classic example is broken/forgotten NaN handling in code that uses floats for calculations
in general this is what we want from our tests, to remind us of where we are wrong about our assumptions in our code. it is likely that you want to use the Unpredictable curve as the defacto choice for testing.
however, note that unpredictable curves are NOT intended:
- to comprehensively cover any particular value space
- to replace property/fuzz testing
- to algorithmically explore edge-cases in an automated fashion
- to assert any particular security or correctness concern
unpredictable curves are a great way to knock off some low hanging fruit, especially around numeric calculations and utf-8 handling, but are no replacement for stringent approaches.
