Workload in Unit testing

Hi all, Ceph documentation mentions it has two types of tests: *unit tests* (also called make check tests) and *integration tests*. Strictly speaking, the *make check tests* are not “unit tests”, but rather tests that can be run easily on a single build machine after compiling Ceph from source . unit tests: https://github.com/ceph/ceph/tree/master/src/test In order to develop on ceph, I am using a Ceph utility, *vstart.sh*, which allows me to deploy fake local cluster for development purpose. I am doing unit testing. And these tests are helping me. Thanks ! My question: How real and big is the workload of unit tests? Are these tests enough for profiling function calls count, loop counts, parallelism to a good extent? Thanks in advance ! BR Bobby !
