What do you mean exactly?

This is something you can do with varnishtest, use your real vcl on a
test backend, and only mock the client.

I actually have such an example in my test suite for the maven plugin:

https://github.com/Zenika/varnishtest-exec/tree/master/varnishtest-maven-plugin/src/it/run-war

You can see in the POM that I'm running the dummy webapp during the
pre-integration-test phase, and shutting it down during the
post-integration-test phase. The varnishtest-maven-plugin is
automatically bound to the integration-test phase:

https://github.com/Zenika/varnishtest-exec/blob/812d894/varnishtest-maven-plugin/src/it/run-war/pom.xml

And a dummy varnishtest case:

https://github.com/Zenika/varnishtest-exec/blob/812d894/varnishtest-maven-plugin/src/it/run-war/src/test/varnish/test.vtc

If it's possible to do that with a twisted build system like maven
(don't get me started;-) you should be able to do the same.
