BOOST_AUTO_TEST_CASE ( AdjacentPinTextNoOverlap )

Test that pin names and numbers don't overlap with adjacent pins at 0° and 90°.

This is the core test for issue 21980. At 0° the pins are horizontal and names/numbers are positioned above/below. At 90° the pins become vertical and names/numbers should be positioned left/right with the same clearance.

◆ BOOST_AUTO_TEST_CASE() [2/3]

BOOST_AUTO_TEST_CASE ( NameAndNumberOnOppositeSides )

Test that name is positioned on opposite side from number (when both are outside).

When pin_name_offset is 0 (names outside), the name should be on one side of the pin and the number on the other side to avoid overlap.

◆ BOOST_AUTO_TEST_CASE() [3/3]

BOOST_AUTO_TEST_CASE ( PerpendicularDistanceConsistentAcrossRotations )

Test that perpendicular distances from pin to text are preserved across rotations.

The Y distance at 0° (horizontal pins) should equal the X distance at 90° (vertical pins). This ensures consistent visual appearance regardless of symbol rotation.
