By relying on distributed monitoring agents that run continuous ping and traceroute tests in a full-mesh fashion, you can validate in real-time that a routing policy change is modifying your routing table as expected.
Routing policy change: due to network complexity, the larger the network, the higher the risk that a routing policy change will have unexpected consequences on your routing table. Circuits or site turn-up: once a new remote site or WAN link is installed, you can verify with a tool like iPerf that you get the bandwidth requested of your carrier and with ping to confirm that the circuit has no packet loss you can also use single-board computers with iperf installed another important thing to test in a new site, is testing what’s the maximum MTU (Maximum Transmission Unit) allowed. In the first case, here are some situations in which you want to validate your design and implementation assumptions after a configuration change: Network testing should be run ad-hoc after a configuration change to validate that everything went well, as well as permanently, via active network monitoring, to detect network problems as soon as they happen. Thus, network testing is a MUST-HAVE step in the network implementation process. In fact, it is sometimes very difficult, or almost impossible, to model a complex system like a large enterprise network, or the Internet itself, in a lab environment. Network testing is very similar to software testing, with one exception: in contrast to software testing, network testing often has to happen in a production environment, after the configuration change was made. Network testing is, in the end, making sure that your network configuration works as designed. Network testing can also provide an objective, independent view of the network to allow the business to appreciate and understand the risks of network implementation. 
“ Network testing is an investigation conducted to provide stakeholders with information about the quality of the product or service under test.
