Detailed Description

Test suite for meander corner radius constraints (issue #8629).

This verifies that meanders maintain visibly rounded corners and do not degenerate to nearly-square shapes when space is constrained.

BOOST_AUTO_TEST_CASE() [2/3]

BOOST_AUTO_TEST_CASE

(

GeometricConstraints

)

Test that corner radius requirements are geometrically consistent.

For a meander with round corners, the corner radius is limited by:

1. Half the amplitude (to fit the U-turn)
2. Half the spacing (to fit between adjacent segments)

If the minimum corner radius (width/2) exceeds these limits, the meander configuration should be rejected.

BOOST_AUTO_TEST_CASE() [3/3]

BOOST_AUTO_TEST_CASE

(

MinCornerRadiusThreshold

)

Test minimum corner radius threshold relative to track width.

For issue #8629, the fix ensures that meanders with corner radii less than half the track width are rejected. This test verifies the relationship between track width and acceptable corner radius.
