title: Add method call in test name with Unroll using Spock
body: <p>I have a code and I want to put method invocation value in the name of the method.</p>
  
  <pre><code>        @Unroll
          def 'check #file other text'() {
          setup:
          def file = allProperties.keySet().getAt(0)
          ...
          where:
          ...
  </code></pre>
  
  <p>Now I create special variable which purpose is only for naming the method. Can I do something like:</p>
  
  <pre><code>        static def allProperties
          def setupSpec(){
             allProperties== [1: 'asd', 2: 'ddd']
          }
          @Unroll
          def 'check #allProperties.keySet().getAt(0) other text'() {
          ....
          where:
          ...
  </code></pre>
  
  <p>Edited: Add setupSpec()</p>
