SSH Forwarding on MacOS X

Forwarding SSH agent

Configure ~/.ssh/config

# Allow Agent forwarding for a specific host (by security)
Host remotehost
  ForwardAgent yes

Motivation

Integrate JMH (Java Microbenchmarking Harness) with Spring (Boot) and make developing and running benchmarks as easy and convinent as writing tests.

Idea

Wrap the necessary JMH boilerplate code within JUnit to benefit from all the existing test infrastructure Spring (Boot) provides. It should be as easy and convinent to write benchmarks as it is to write tests.

TL;DR;
