Detailed Description

Unit tests for Astra1DDynamic fieldmap class.

Tests cover:

Parsing & metadata:

• File parsing
• Frequency parsing and conversion (MHz -> angular frequency)
• Field dimension retrieval (z-bounds)

Field evaluation:

• Point field evaluation via getFieldstrength()
• Uniform on-axis field correctness
• Static computeField() correctness for simple coefficients
• Reconstructed on-axis field via getOnaxisEz()
• Device-safe RF cavity helper via computeRFField()
• Device-safe traveling-wave helper via computeTravelingWaveField()

Geometry & bounds:

• Behaviour outside z-range
• isInside() helper (boundary semantics)

API behaviour:

• getFieldDerivative() for simple constant field
• getFrequency() correctness
• getInfo() does not crash
• swap() does not crash

Robustness:

• Missing / invalid file handling
• Fieldmap dictionary caching
• readMap() / freeMap() lifecycle correctness

Semantics:

• Field accumulation: E and B are accumulated, not overwritten
  • Notes:
• The current Astra1DDynamic preprocessing / Fourier reconstruction yields an amplitude factor of (nz - 1) / nz for uniform input fields. The tests reflect the current implementation behaviour.
