# Add thresholds to your script

Thresholds turn your baseline numbers into automated pass/fail criteria. When a threshold is breached, k6 exits with a non-zero exit code, which means you can integrate baseline enforcement into CI/CD pipelines. This is the second key technical milestone that many new users skip. Without thresholds, your test only reports numbers but never fails.

To add thresholds to your baseline script, complete the following steps:

1. Open `baseline.js` and add a `thresholds` property to the `options` object:
   
   JavaScript ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy
   
   ```javascript
   export const options = {
     stages: [
       { duration: '30s', target: 20 },
       { duration: '1m', target: 20 },
       { duration: '30s', target: 0 },
     ],
     thresholds: {
       http_req_duration: ['p(95)<500'],
       http_req_failed: ['rate<0.01'],
     },
   };
   ```
   
   Each threshold is a metric name mapped to an array of conditions. The `p(95)<500` condition means the test fails if more than 5% of requests take longer than 500 ms. The `rate<0.01` condition means the test fails if more than 1% of requests return errors.
2. You can also add thresholds on your checks to ensure correctness stays above a minimum rate:
   
   JavaScript ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy
   
   ```javascript
   thresholds: {
     http_req_duration: ['p(95)<500'],
     http_req_failed: ['rate<0.01'],
     checks: ['rate>0.99'],
   },
   ```
   
   The `checks` threshold fails the test if the overall check pass rate drops below 99%.
3. Save the file. Your complete `baseline.js` should now look like this:
   
   JavaScript ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy
   
   ```javascript
   import http from 'k6/http';
   import { check, sleep } from 'k6';
   
   export const options = {
     stages: [
       { duration: '30s', target: 20 },
       { duration: '1m', target: 20 },
       { duration: '30s', target: 0 },
     ],
     thresholds: {
       http_req_duration: ['p(95)<500'],
       http_req_failed: ['rate<0.01'],
       checks: ['rate>0.99'],
     },
   };
   
   export default function () {
     const res = http.get('https://quickpizza.grafana.com');
   
     check(res, {
       'status is 200': (r) => r.status === 200,
       'response body is not empty': (r) => r.body.length > 0,
     });
   
     sleep(1);
   }
   ```
   
   > Note
   > 
   > You can define multiple conditions per metric. For example, `http_req_duration: ['p(95)<500', 'p(99)<1000']` requires both the p95 and p99 to stay within their respective limits.

In the next milestone, you validate that your thresholds work by running the test and checking the exit code.
