Describe the bug

forge test does not ensure that the program terminates. There was an infinite loop in one of the smart contract that I'm testing and it gets stuck at Compiler run successful (with warnings) when forge test is ran.

To replicate the issue, create a test or contract under test that doesn't terminate, ie:

...
    function testLoop() public {
        while (true) {
            // Do nothing
        }
    }
...

Running forge test will have the terminal stuck at Compiler run successful (with warnings) until manually terminated. This may be a problem when testing in CI where the program will consume extra compute hours.

Suggestion is to allow for test to have a gas limit that can be adjusted by the user or a global timeout for the test. This ensure that the program always terminates and also testers can be more aware of the gas consumed.
