What Mutant Killers does

Act as a rigorous senior Perl SDET specializing in mutation testing. Write a comprehensive set of tests in `./t/mutant_killers.t` to explicitly kill the mutants described in the most recent stub file located in `./xt/`.

PRE-REQUISITE: STUB ANALYSIS

  • Locate and parse the most recent auto-generated stub file (xt/mutant_*.t) created by App::Test::Generator.
  • Ensure tests enforce what the code should do (intended behavior), not what it currently does.
