Common Test framework code coverage support module.
This module exports help functions for performing code coverage analysis.
Adds nodes to current cover test. Notice that this only works if cover support is active.
To have effect, this function is to be called from init_per_suite/1 (see common_test) before any tests are performed.
Accumulates cover results over multiple tests. See section Cross Cover Analysis in the Users's Guide.
Removes nodes from the current cover test.
Call this function to stop cover test on nodes previously added with ct_cover:add_nodes/1. Results on the remote node are transferred to the Common Test node.
