title: How can I set the path to Instruments on Appium?
body: <p>I'm trying to run Appium for an iOS application, but it seems that the path to instruments is invalid. How can I set it? Is there an environment variable I should use? Or some argument? Even I could change that in the source code it would be useful for me :)</p>
  
  <p>Here's the relevant part of the log I receive from Appium:</p>
  
  <pre><code>info: instruments is: 
  info: [INSTSERVER] Instruments socket server started at /tmp/instruments_sock
  info: Spawning instruments with command:  -t /usr/local/lib/node_modules/appium/app/uiauto/Automation.tracetemplate /var/folders/rd/z5t93lfj0cx0wm2_hqmthnkr0000gn/T/TestApp.app -e UIASCRIPT /usr/local/lib/node_modules/appium/app/uiauto/bootstrap.js -e UIARESULTSPATH /tmp/appium-instruments/
  </code></pre>
  
  <p>Thanks!</p>
