title: Vue test utils not recognising $http in the tests
body: <p>Have a Vue app with axios setup and is using it as <code>this.$http.get</code> in the components and that is working fine.</p>
  
  <p>In running the specs using Jest I get an error: <code>Cannot read property 'get' of undefined</code></p>
  
  <p>I know I can mock axios with maxios. How do I get Jest to recognise $http so it does not throw an error?</p>
