Abstract methods

def run[R1 <: R & TestConfig, F[_] : CapsF, A : Caps](genF: GenF[R1, F], gen: Gen[R1, A]): ZIO[R1, Nothing, TestResult]

Test that values of type F[+_] satisfy the laws using the specified function to construct a generator of F[A] values given a generator of A values.

Concrete methods

def +[CapsF1 <: ([x[_]] =>> CapsF[x]), Caps1 <: (Caps), R1 <: R](that: Covariant[CapsF1, Caps1, R1]): Covariant[CapsF1, Caps1, R1]

Combine these laws with the specified laws to produce a set of laws that require both sets of laws to be satisfied.
