Allure reports are not generated in Protractor
<p>I included the below code in my <code>conf.js</code> file but the Allure reports are not getting generated.</p>

<pre><code>onPrepare : function() {
    var AllureReporter = require('jasmine-allure-reporter');
    jasmine.getEnv().addReporter(
        new AllureReporter({
            allureReport : {
                resultsDir : 'allure-results'
            }
        })
    );

    jasmine.getEnv().afterEach(function(done) {
        browser.takeScreenshot().then(function(png) {
            allure.createAttachment('Screenshot', function() {
                return new Buffer(png, 'base64')
            }, 'image/png')();
            done();
        })
    });
}
</code></pre>

<p>Please let me know if I am missing anything.<br>
Thanks,<br>
Srinivas</p>
