title: xctool ...ERROR: build-tests: '' is not a testing target in this scheme
body: <p>i try to run my Xcode UI Tests and just a specific method. It isn't possible with the default <strong>xcodebuild</strong> command line from apple. I found the <strong>xctool</strong> but the tool didn't found my UITestsTarget. </p>
  
  <p>Here my command line: </p>
  
  <pre><code>/path/to/xctool -workspace APP.xcworkspace -scheme "APPScheme" test -only UITestsTarget:UITestsClass/UITestsMethod
  </code></pre>
  
  <p>and i got this error: ...ERROR: build-tests: 'UITestsTarget' is not a testing target in this scheme.</p>
  
  <p>with <code>xcodebuild list</code> i can see all the informations about project and i see my UITestsTarget.</p>
  
  <p>has someone any ideas?
  Cheers</p>
