Detailed Description

This test verifies the accuracy of the private GetRandomNumTransmitters() method in the TvSpectrumTransmitterHelper class.

The method generates a random number corresponding to the number of TV transmitters to create based on the given location density (low, medium, or high) and maximum possible number of TV channels. Low density will generate a transmitter for between one (a single transmitter) and one third of the number of possible channels, medium density will generate a transmitter for between one third and two thirds, and high density will generate a transmitter for between two thirds and all of the possible channels. In this test, it is verified that the lower (1) and upper (max number of possible channels input) bounds are not exceeded and that the number of transmitters to be generated does not overlap between adjacent densities. For example, given 60 possible channels, for low density between 1 and 20 transmitters can be created, for medium density between 21 and 40 transmitters can be created, and for high density between 41 and 60 transmitters can be created (all inclusive). This is tested with various cases.
