There are many Website Load Testing applications, here are some I recently tested. This post is to simply record some screenshots and steps I were using them.

You will be asked to verify the ownership of this host by uploading a assigned file to it.If you have paid plan, you will be able to use DNS as verification method. 

2. Create a new test and run a test

3. Watch the testin real-time.

    { duration: '3m', target: 20 },

    { duration: '1m', target: 0 },

  ],

  thresholds: {

    http_req_failed: ['rate<0.02'], // http errors should be less than 2%

    http_req_duration: ['p(95)<2000'], // 95% requests should be below 2s

  },

  ext: {

    loadimpact: {

      distribution: {

        'amazon:us:ashburn': { loadZone: 'amazon:us:ashburn', percent: 100 },

      },

    },

}

export default function main() {

  let response = http.get('https://blog.51sec.org/')

  sleep(1)

}

Notes:

If you have enabled Cloudflare security features to protect your website, such as WAF, Bots , you had better to disable them first. Else you will get failed error on your K6 test page since CloudFlare will send out JS Challenge to fight back to those suspicious traffic.
