SmallK

Tests


Below we provide example output for many of the tests that can be run in the SmallK library. This will provide guidance for identifying issues with your installation. Of course results will vary on different machines.

SmallK Test Results

After building the smallk library, the ‘make check’ command will run a bash script that performs a series of tests on the code. This is a sample output of those tests:
