Search if a string exists in the response body

Grafana k6 OSS Support

Hi, I am wondering if there is a good way to search if a particular string exists in response body. I am talking about like a global search in the entire parsed response body without knowing where it might be exactly. I looked at Selection and couldn’t find a way.
Javascript search() or in operator seems to be not working in k6.
Please let me know. Thanks!

Hi @yli , you can use includes() function in the body part like this:

export default function () {
  const response1 = http.get('http://myapp:5000/',  {tags: {name: '/'}});
  check(response1, {
    'verify homepage text': (r) => r.body.includes('Python is fun'),
    "status is 200": (r) => r.status === 200 
  });  
  sleep(0.2)
};

Another way to search a value in a body part that i know is this:

const cheerio = require('cheerio');
function validateElement() {
    const res = http.get('https://loadimpact.com/');
    const $ = cheerio.load(res.body);
  
    const title = $('head title').text();
    check(title, {
      'has correct title': () => title == 'Load Impact is now k6',
    });
    console.log(title);

    return title;
}

I share you this info i hope it helps:

Greetings :smiley:

They both work perfectly. You are awesome.

The includes() method was actually documented here (Checks) but it’s not searchable and I missed it.

Thanks again!

This might be because includes is actually part of JavaScript :slight_smile:
