Extreme Feedback Device Jun 2015

• Nashorn
• Javascript
• Jenkins

lights takes your build server's status via http and controls a feedback device accordingly. As hardware lights is tied to Cleware's traffic lights - it uses a windows command for controlling the lamp.

While I currently use Jenkins as a build server lights could be adapted to any build server quite easily. Capturing the status via http has been implemented with Java's scripting API using Nashorn (Java 8 scripting engine). Example for integrating with jenkins:

function getScore(url) {
  var jsonStr = rest.get(url);
  var json = JSON.parse(jsonStr);
  if (json.healthReport.length == 1) {
    return 0;
  }
  var index = 0;
  if (json.healthReport.length == 2 && json.healthReport[1].description.startsWith("Testergebnis")) {
    index = 1;
  }
  return parseInt(json.healthReport[index].score);
}

var unitTestsScore = getScore("http://...:8080/job/projA/api/json");
var iTestsScore = getScore("http://...:8080/job/projB/api/json");

if (unitTestsScore == 0) {
  command.red.set(true, 2000, 2000);  // blinking
  command.yellow.set(false);
  command.green.set(false);
} else if (unitTestsScore < 100) {
  command.red.set(true);
  command.yellow.set(false);
  command.green.set(false);
} else if (iTestsScore < 100) {   ...
