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.
