Testing Results

Result value testing

filtering with filter

• Result.valid(42).filter(_ == 42, 1337) ==== Valid(42)

• Result.valid(42).filter(_ != 42, 1337) ==== Invalid(1337)

• Result.invalid(1337).filter(_ == 42, 42) ==== Invalid(1337)

checking for validity

• Result.valid(42).isValid ==== true

• Result.invalid(1337).isValid ==== false

• Result.valid(42).isInvalid ==== false

• Result.invalid(1337).isInvalid ==== true

exists tests if a Result is valid and a predicate holds

• Result.valid(42).exists(_ == 42) ==== true

• Result.valid(42).exists(_ == 1337) ==== false

• Result.invalid(42).exists(_ == 42) ==== false

• Result.invalid(42).exists(_ == 1337) ==== false

forall tests if a Result is either invalid or satisfies a predicate

• Result.valid(42).forall(_ == 42) ==== true

• Result.valid(42).forall(_ == 1337) ==== false

• Result.invalid(42).forall(_ == 42) ==== true

• Result.invalid(42).forall(_ == 1337) ==== true

contains tests if a Result has a specific valid value

• Result.valid(42).contains(42) ==== true

• Result.valid(42).contains(1337) ==== false

• Result.invalid(42).contains(42) ==== false

• Result.invalid(42).contains(1337) ==== false
