title: How to skip test Nightwatch.js?
body: <p>I use nightwatch.js, mocha.js and selenium web driver for acceptance testing for now.
  And I need to skip some tests, how I can do it?</p>
  
  <pre><code>module.exports = {
  
  "User logs in the WebPortal": function(browser) {
  browser
    .url(urlAdress)
    .setValue('input#login', user.login)
    .setValue('input#password', user.password)
    .click('button.ui-button')
    .waitForElementPresent('a[href="/logout"]', middleTimer)
    .getText('a[href="/logout"] span', function(result) {
      (result.value).should.be.exactly("logout")
    })
    .end()
  },
  "User logs out": function(browser) {
  browser
    .url(urlAdress)
    .setValue('input#login', user.login)
    .setValue('input#password', user.password)
    .click('button.ui-button')
    .waitForElementPresent('a[href="/logout"]', middleTimer)
    .click('a[href="/logout"]')
    .waitForElementPresent('button.ui-button', middleTimer)
    .getText('button.ui-button', function(result) {
      (result.value).should.be.exactly("Login")
    })
    .end()
  }
  }
  </code></pre>
  
  <p>So, how to skip one or more tests?
  Thank you for answers.</p>
