Class dsp::test::TScrunchTest

class TScrunchTest : public testing::TestWithParam<TScrunchTestParam>, public dsp::test::TransformationTestHelper<TimeSeries, TimeSeries>

A value-parameterized test suite for TScrunchTest class.

Public Functions

dsp::TScrunch *new_device_under_test()

Construct and configure the dsp::TScrunch object to be tested.

void generate_data()

Generate test data for input to TScrunch::transform.

void assert_data()

Compare data output by TScrunch::transform against expectations.

float get_expected_value(unsigned ichan, unsigned nchan, unsigned ipol, uint64_t odat, unsigned sfactor)

Get the expected input or output value for the timeseries.

input data are computed as: ((ichan/nchan) * sample_index) + ipol output data are computed as the sum of corresponding input data for the scrunch factor

Parameters:

• ichan – channel number

• nchan – total number of channels

• ipol – polarisation number

• odat – output time sample

• sfactor – time scrunch factor

Returns:

float value that corresponds to the input

void assert_transform_configurations(dsp::TScrunch*)

Helper function for asserting transform configurations.

void assert_fpt()

Helper function for asserting FPT-ordered data.

void generate_fpt()

Helper function for populating the input container with FPT-ordered data.

void assert_tfp()

Helper function for asserting TFP-ordered data.

void generate_tfp()

Helper function for populating the input container with TFP-ordered data.
