I was following the steps from README.md to learn about SwiftCheck.
Unfortunately, the example for complex properties doesn't compile:
property("Shrunken lists of integers always contain [] or [0]") <- forAll { (l : [Int]) in
// Here we use the Implication Operator `==>` to define a precondition for
// this test. If the precondition fails the test is discarded. If it holds
// the test proceeds.
return (!l.isEmpty && l != [0]) ==> {
let ls = self.shrinkArbitrary(l)
// ^ Value of type 'ExampleTests' has no member 'shrinkArbitrary'
return (ls.filter({ $0 == [] || $0 == [0] }).count >= 1)
}
}
I'm no expert on QuickCheck (or SwiftCheck), so I don't know how to fix this message.
Steps To Reproduce
Create a new test function
Copy the code block from README.md
Expected Result
The code compiles and produces a passing test case.
Actual Result
There is a compiler error:
Value of type 'ExampleTests' has no member 'shrinkArbitrary'
