how can I subscribe to mocha suite events?

Question

I\'d like to be able to extend the mocha test results and listen to them from the available mocha object. First, I\'m looking at getting the \"passes\" results.

Answer 1

I did some more digging in mocha.js and finally discovered that mocha.run() actually returns the runner which emits all the events I was looking.

The original example I was using only had: mocha.run()

So if Mocha.run() returns a runner, then I realized that I could subscribe to it:

 var runner = mocha.run();
 var testsPassed = 0;

 var onTestPassedHandler = function(e){
      testsPassed++;
      console.log("onTestPassedHandler - title: " + e.title + " - total:" + testsPassed);

    };

 runner.on("pass", onTestPassedHandler);


    /**
     *  These are all the events you can subscribe to:
     *   - `start`  execution started
     *   - `end`  execution complete
     *   - `suite`  (suite) test suite execution started
     *   - `suite end`  (suite) all tests (and sub-suites) have finished
     *   - `test`  (test) test execution started
     *   - `test end`  (test) test completed
     *   - `hook`  (hook) hook execution started
     *   - `hook end`  (hook) hook complete
     *   - `pass`  (test) test passed
     *   - `fail`  (test, err) test failed
     */ 

much better!

You can also get similar events at

mocha.suite.beforeEach(function() {} )
mocha.suite.afterEach(function() {} )
mocha.suite.afterAll( function() {} )
