It is the purpose to raise such "load" to evaluate the SUT if it +could provide an acceptable level of service or level of confidence during such +circumstances. In Danube and Euphrates, we only considered the stress test with +excess load over OPNFV Platform. + +In Danube, Bottlenecks and Yardstick project jointly implemented 2 stress tests +(concurrently create/destroy VM pairs and do ping, system throughput limit) +while Bottlenecks acts as the load manager calling yardstick to execute each +test iteration. These tests are designed to test for breaking points and provide +level of confidence of the system to users.
