Detailed Description

Unit tests for TravelingWave component.

This test suite validates the core behavior of TravelingWave using:

• a minimal concrete implementation (TestTravelingWave)
• a controlled fake fieldmap (FakeTWFieldmap)

---

Coverage

1. Basic API
   • getType()
   • bends()
   • amplitude / frequency / phase setters and getters
2. Geometry
   • getFieldExtend()
   • getElementDimensions()
   • getEdgeToBegin()
   • getEdgeToEnd()
3. Spatial behavior
   • apply() in entry region
   • apply() in core region
   • apply() in exit region
   • apply() outside the element
4. Traveling-wave phase behavior
   • setPhasem() updates internal phaseCore1_m / phaseCore2_m / phaseExit_m
5. Field superposition
   • core region accumulates two field contributions
6. Scaling behavior
   • entry / core / exit scales act correctly
7. Fieldmap interaction / edge cases
   • correct handling of out-of-bounds fieldmap queries
   • isInside()

---

Notes

• The FakeTWFieldmap provides a simple, deterministic field: E = (1, 0, 0), B = (0, 1, 0) allowing direct verification of cos/sin modulation and accumulation.
• Tests focus on physics/logic correctness of TravelingWave region handling.
