Member Function Documentation

checkExitConditions()

bool isc::perfdhcp::BasicScen::checkExitConditions ( )

protected

Check if test exit conditions fulfilled.

Method checks if the test exit conditions are fulfilled. Exit conditions are checked periodically from the main loop. Program should break the main loop when this method returns true. It is calling function responsibility to break main loop gracefully and cleanup after test execution.

Returns

true if any of the exit conditions is fulfilled.

run()

int isc::perfdhcp::BasicScen::run ( )

overridevirtual

brief\ Run performance test.

Method runs whole performance test. Command line options must be parsed prior to running this function. Otherwise function will throw exception.

Exceptions

isc::InvalidOperation	if command line options are not parsed.
isc::Unexpected	if internal Test Controller error occurred.

Returns

execution status.

Todo

: need to implement adaptive time here, so the sleep time is not fixed, but adjusts to current situation.

Implements isc::perfdhcp::AbstractScen.
