1. Smoke test

Introduce

have access to k6 Perform multiple types of tests , Each type has different uses .

Each type of test is designed to give you different insights into the system :

• Smoke Test The function of is to verify whether your system can handle the minimum load , No problem .

• The load test It mainly involves evaluating the performance of the system in terms of concurrent users or requests per second .

• Stress test and peak test It involves evaluating the limit and stability of the system under extreme conditions .

• Soak Test It can let you know the reliability and performance of the system in a long time .

• The important thing to understand is , Each test can be executed using the same test script . You can write a script and use it to perform all the above tests . The only change is the test configuration , Logic remains unchanged .

• Different test types will teach you different knowledge about the system , And provide you with the insight you need to understand or optimize performance .

Smoke testing

smoke test It's a routine load test , Configured for minimum load . Every time you write a new script or modify an existing script , You all want to run smoke test As an integrity check .

You want to run smoke test With ：

1. Verify that your test script has no errors .

2. Verify that your system will not cause any errors under minimum load .

k6 Run simple somke test

import http from 'k6/http';
import {
     check, group, sleep, fail } from 'k6';

export let options = {
    
  vus: 1, // 1  A user cycle  1  minute 
  duration: '1m',

  thresholds: {
    
    http_req_duration: ['p(99)<1500'], // 99%  Your request must be in  1.5  seconds 
  },
};

const BASE_URL = 'https://test-api.k6.io';
const USERNAME = 'TestUser';
const PASSWORD = 'SuperCroc2020';

export default () => {
    
  let loginRes = http.post(`${
      BASE_URL}/auth/token/login/`, {
    
    username: USERNAME,
    password: PASSWORD,
  });

  check(loginRes, {
    
    'logged in successfully': (resp) => resp.json('access') !== '',
  });

  let authHeaders = {
    
    headers: {
    
      Authorization: `Bearer ${
      loginRes.json('access')}`,
    },
  };

  let myObjects = http.get(`${
      BASE_URL}/my/crocodiles/`, authHeaders).json();
  check(myObjects, {
     'retrieved crocodiles': (obj) => obj.length > 0 });

  sleep(1);
};

If your smoke test produces any errors , You must correct the script or repair your environment , Before we can continue .

The output is as follows :

Once your smoke Test display 0 A mistake , As shown in the screenshot above , You can go to the next step and execute The load test To evaluate the performance of the system
