In this section we describe the test suites included with the antenna module that verify its correct functionality.
The unit test suite angles verifies that the Angles class is
constructed properly by correct conversion from 3D cartesian
coordinates according to the available methods (construction from a
single vector and from a pair of vectors). For each method, several
test cases are provided that compare the values 
determied by the constructor to known reference values. The test
passes if for each case the values are equal to the reference up to a
tolerance of 
which accounts for numerical errors.
The unit test suite degrees-radians verifies that the methods
DegreesToRadians and RadiansToDegrees work properly by
comparing with known reference values in a number of test
cases. Each test case passes if the comparison is equal up to a
tolerance of which accounts for numerical errors.
The unit test suite isotropic-antenna-model checks that the IsotropicAntennaModel class works properly, i.e., returns always a 0dB gain regardless of the direction.
The unit test suite cosine-antenna-model checks that the CosineAntennaModel class works properly. Several test cases are provided that check for the antenna gain value calculated at different directions and for different values of the orientation, the reference gain and the beamwidth. The reference gain is calculated by hand. Each test case passes if the reference gain in dB is equal to the value returned by CosineAntennaModel within a tolerance of 0.001, which accounts for the approximation done for the calculation of the reference values.
The unit test suite parabolic-antenna-model checks that the ParabolicAntennaModel class works properly. Several test cases are provided that check for the antenna gain value calculated at different directions and for different values of the orientation, the maximum attenuation and the beamwidth. The reference gain is calculated by hand. Each test case passes if the reference gain in dB is equal to the value returned by ParabolicAntennaModel within a tolerance of 0.001, which accounts for the approximation done for the calculation of the reference values.
