QuidemTest

public QuidemTest()

Method Details

useTopDownGeneralDecorrelator

protected boolean useTopDownGeneralDecorrelator()

data

protected static Collection<String> data(String first)

data

protected static Collection<String> data(String first,
 String substring)

Debugging helper which returns only a subset of the files produced by data(first).

Parameters:

first - File path indicating where IQ files are searched.

substring - Only files that contain this substring are returned.

Returns:

The list of IQ files produced by data(first) which match the restriction.

I find that often when I debug quidem tests it is handy to only run the currently modified file. By replacing the call to data(first) with a call to data(first, restricted) one can easily just run the new tests. But do not forget to undo this change when submitting the final PR!
