What if tests were part of production code?

Most testing frameworks focus on catching bugs, but what if we could prevent them from the start? BeyondTesting.dev explores Design by Contract (DbC)—a methodology where software correctness is built-in, not patched later.

We believe in:

• Self-verifying code with contracts
• Fewer tests, more guarantees
• Provably correct software
