MODULE
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

    Add nodes to current cover test (only works if cover support is active!). To have effect, this function should be called from init_per_suite/1 before any actual tests are performed.

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

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

    Remove nodes from current cover test. Call this function to stop cover test on nodes previously added with add_nodes/1. Results on the remote node are transferred to the Common Test node.
