Testing Domains Various other Testing Domains Test::ManyParams - test subroutine against many different inputs test one sub against many arguments: all_ok {bar(shift())} [qw/arg1 arg2 arg3 arg4 arg5 arg6/], "Testing every argument with bar"; Test::Differences - Test strings and data structures and show differences if not ok Test::Env - test the environment provides env_ok(NAME, VALUE) for testing values of environment strings Test::File - test file attributes many tests for file attributes, e.g.: file_exists_ok( FILENAME [, NAME ] ) file_readable_ok( FILENAME [, NAME ] ) file_not_empty_ok( FILENAME [, NAME ] ) file_size_ok( FILENAME, SIZE [, NAME ] ) file_max_size_ok( FILENAME, MAX [, NAME ] ) file_executable_ok( FILENAME [, NAME ] ) ... Test::Warn - test methods for warnings test that functions throw appropriate warnings in given situations, e.g.: warning_is {foo(-dri => "/")} "Unknown Parameter 'dri'", "dri != dir gives warning"; warnings_are {bar(1,1)} ["Width very small", "Height very small"]; warning_is {add(2,2)} undef, "No warning to calc 2+2";
