[back to package description]Tasty Lens
Preassembled tasty TestTrees
with sensible defaults for the validation of:
LensSetterTraversalIsoPrism
Although these tests offer weaker guarantees compared to manually proving the laws through equational reasoning, they can still be useful for regression testing where you don't want to manually proof every time you make a slight change that could affect the laws.
It uses smallcheck-lens
under the hood. If you don't find any functions to create the TestTrees you
are looking for, you may want to use the smallcheck-lens package directly.
In such case you can still check this package as a reference to implement your
own smallcheck-lens TestTrees.
Check the tests in this package for usage examples.
