Whiley employs state-of-the-art techniques for ensuring your software is correct. You can specify functions using preconditions and postconditions, and then statically verify( your implementation meets its specification.
Whiley is an independently developed open source project and is free to use. Join our community on our Discord channel, follow us on Twitter and contribute to the code on GitHub.
