In the testFootprintsMeasure function in tests/test_measure.py in meas_algorithms, the test claims to "Check that we can measure the objects in a detectionSet". All of the "asserts" of the test occur within a loop over the sources in measCat (here). HOWEVER, when I run this test, I get 0 detections, so that loop is never entered and no assertions get made (which I noticed when I was not seeing any dots on the sources in ds9 when updating the display code). It seems that something is seriously amiss if we are expecting (it looks like at least 3) detections but getting 0.  (I also think I see this as the line

measurement INFO: Measuring 0 sources (0 parents, 0 children)

in Jenkins artifact files, e.g. here, so it's not just a local setup issue).

Also, in the testDetection function, nothing is actually "asserted" in the function, so it seems that the "test" is that it does not crash when running through the operations? Would a check on a (minimum?) number of detections be appropriate here?
