Run function when Karma test fails

[bracketdash]

I've been scouring the internet today for a way to run some code whenever a Karma test fails with no luck. If there is a way to do this, could someone help me out? If there's not a way to do that currently, I guess this becomes a feature request.

Specifically, I'm working with Jasmine and I assume I would have to use the public API to start a server in Node. What I'm looking for is something like...

var server = require('karma').server;
server.start({port: 9877}, function(exitCode) {
  console.log('Karma has exitted with ' + exitCode);
  process.exit(exitCode);
});
server.onTestFail(function(tests){
  console.log('Test information collection follows...');
  console.log(tests);
});

Where the tests object would include which tests failed and any other information the log would normally have about the failed test.
