Description

It would be very cool if Kontrol could generate executable counter-examples. Here is a small example:

function prove_foo(uint256 bar) {
    assert(bar != 0xC0FFEE);
}

Kontrol fails and gives us a counter-example with bar = 0xC0FFEE. It would be even nicer if Kontrol could generate an executable unit test like this:

function prove_foo_1() {
    prove_foo(0xC0FFEE);
}

If we can make the generated test fully concrete and self-contained, it would make an excellent entry point for Simbolik, and it can be easily added as a regression test to CI.

Research direction

No source files or tests are identified. Start by tracing how Kontrol produces the Solidity counter-example for the shown assertion, then determine where a fully concrete, self-contained unit test could be generated and added as a CI regression test.
