NAME

       ct_cover - Common Test framework code coverage support module.

DESCRIPTION

       Common Test framework code coverage support module.

       This module exports help functions for performing code coverage analysis.

EXPORTS

       add_nodes(Nodes) -> {ok, StartedNodes} | {error, Reason}

              Types:

                 Nodes = [atom()]
                 StartedNodes = [atom()]
                 Reason = cover_not_running | not_main_node

              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.

       cross_cover_analyse(Level, Tests) -> ok

              Types:

                 Level = overview | details
                 Tests = [{Tag, Dir}]
                 Tag = atom()
                 Dir = string()

              Accumulates cover results over multiple tests. See section Cross Cover  Analysis  in  the  Users's
              Guide.

       remove_nodes(Nodes) -> ok | {error, Reason}

              Types:

                 Nodes = [atom()]
                 Reason = cover_not_running | not_main_node

              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.
