Solution: Plan two checks

Here is a possible solution to the task.

Code

use Test;

plan 2;

my @sorted = (3, 1, 2).sort;
is-deeply @sorted, [1, 2, 3], 'sorted';

is 10 % 3, 1, 'remainder';

🦋 You can find the source code in the file test-a-list.raku.

Output

1..2
ok 1 - sorted
ok 2 - remainder

Comments

  1. plan 2 states the count before any test runs, so the 1..2 line appears first. If the file then ran a different number of checks, the suite would be reported as failing — a safeguard done-testing cannot give you.

  2. is-deeply compares the two lists for exact, type-aware equality. Sorting 3, 1, 2 gives 1, 2, 3, which matches.

  3. is compares two values for plain equality and reports both on failure. Here 10 % 3 is 1, which matches the expected value, so the second test passes too.
