cargo-mutants 0.2.0

0.2.0

Released 2022-02-06

• A new --timeout SECS option to limit the runtime of any cargo test invocation, so that mutations that cause tests to hang don't cause cargo mutants to hang.

  A default timeout is set based on the time to run tests in an unmutated tree. There is no timeout by default on the unmutated tree.

  On Unix, the cargo subprocesses run in a new process group. As a consequence ctrl-c is explicitly caught and propagated to the child processes.

• Show a progress bar while looking for mutation opportunities, and show the total number found.

• Show how many mutation opportunities were found, before testing begins.

• New --shuffle option tests mutants in random order.

• By default, the output now only lists mutants that were missed or that timed out. Mutants that were caught, and mutants that did not build, can be printed with --caught and --unviable respectively.
