test: assert reference rows have the expected number of values

[kilo-code-bot]

What this PR changes

test_example in tests/test_examples.py truncated each computed row to the reference length (table[method][:len(expected)]), silently ignoring any extra columns a script might start producing. It now asserts the row length matches the reference before comparing values.

Why

CodeRabbit flagged the truncating comparison in the earlier version of this test; that code was rewritten, but the truncation survived in test_example. This closes the still-valid part: an added column (e.g. a new n_cands/n_voters/condition) now fails the test instead of being masked.

Tests

The example tests themselves (run with pytest -m slow); the length assertion is a no-op for the current scripts since every reference row already matches its output length.

Summary by CodeRabbit

• Bug Fixes
  • Improved example validation to detect empty output tables.
  • Ensured generated rows match the expected number of values exactly.
  • Updated comparisons to validate complete result rows.

PR Summary

• Enhanced Error Message for Assertion
  The message displayed when the lengths of parameters 'got' and 'expected' are validated for equality has been improved to be more informative.

• Enhanced Assertion for table[method] and expected
  Altered the checks to verify that the lengths of table[method] and expected are identical, this change will make error reports more meaningful if they are not matching.

• Adjusted Use of np.testing.assert_allclose
  Modified the call of np.testing.assert_allclose method to use table[method] directly in place of its sliced version, for more accurate and efficient testing.
