+#### Integration testing in Xiringuito
+
+We do integration testing with Docker against two platforms:
+* Ubuntu 16.04
+* CentOS 7
+
+Next cases (and even more) are covered:
+* Running with SSH agent
+* Running with SSH private key loaded directly from FS
+* With invalid SSH keys or w/o ones (predictable failure)
+* With and without route discovery
+* With and without reconnection
+* With and without propagation of server DNS configuration
+* Tearing down both client and server with no garbage left
