Integration test for few different versions of jira-server

[Wojciech Tartanus]

I'm trying to set up an integration test against a few different versions of jira-server. In https://developer.atlassian.com/server/framework/atlassian-sdk/create-and-run-traditional-integration-tests/ I've found a configuration where is possible to specify products and versions for which I want to run a test. Example from my code: 

 <products> 
  <product> 
   <id>jira</id> 
   <instanceId>jiraExpected</instanceId> 
   <productVersion>7.13.0</productVersion> 
   <productDataVersion>7.13.0</productDataVersion> 
  </product> 
  <product> 
    <id>jira</id> 
    <instanceId>jira-7.0.0</instanceId> 
    <productVersion>7.0.0</productVersion> 
    <productDataVersion>7.0.0</productDataVersion> 
  </product> 
 </products>

 Test runs fine, but I can't see any difference between running test with this configuration and without. Shall I see in logs that test been run twice against 2 different versions?
