Module Summary

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.

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.

OTP R16B

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.

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.
