Common test framework code coverage support module.
Common Test Framework code coverage support module.
This module exports help functions for performing code coverage analysis.
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.
cross_cover_analyse(Level, Tests) -> ok
Types:
Level = overview | details
Tests = [{Tag, Dir}]
Tag = atom()
Dir = string()
Accumulate cover results over multiple tests. See the chapter about cross cover analysis in the users's guide.
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.
