nightwatch-api-automation

mkdir nightwatch-api-automation

Install Nightwatch

npm init nightwatch nightwatch-api-automation

npm i @nightwatch/apitesting --save-dev

Go to nightwatch.conf.js

change plugins: [], to plugins: ['@nightwatch/apitesting'],

In same config file (nightwatch.conf.js)

under test_settings: {} , after default: {} add a new object [ config] like this ( you may copy paste )

api_testing: {
	  start_session: false,
	    webdriver: {
	      start_process: false,
	  }
	},

So

    webdriver: {
        start_process: true,
        server_path: ''
      },
      
    },
    
    chrome: {
      desiredCapabilities: {

becomes

    webdriver: {
        start_process: true,
        server_path: ''
      },
      
    },

	api_testing: {
	  start_session: false,
	    webdriver: {
	      start_process: false,
	  }
	},
    
    chrome: {
      desiredCapabilities: {

now lets create a simple API test file and run it:

creat a file under test/API/ named api-test.js and create a test, or try with this ( copy paste) ref : https://github.com/nightwatchjs/nightwatch-docs/blob/versions/3.0/guide/writing-tests/api-testing.md#test-api-headers--responses

describe('api testing', function () {
  it('get api test', async function({supertest}) {
    await supertest
      .request("https://petstore.swagger.io/v2")
      .get("/pet/findByStatus?status=available")
      .expect(200)
      .expect('Content-Type', /json/)
      .then(function(response){
          expect(response._body.length).to.be.greaterThan(0);
      });
  });
});

run it

npx nightwatch test/API/api-test.js --env api_testing

api_testing tells it to run API testing only [ not browser testing as we configured in above steps]

You can also add a short command in package.json file like I added for this project :

npm test

now to see API tetsing in action

$ npx nightwatch test/API/api-test.js --env api_testing

 Wrote HTML report file to: ./nightwatch-api-automation/tests_output/nightwatch-html-report/index.html

nightwatch_report {HTML}

"@nightwatch/apitesting" : {
    "log_responses": true
  }

So, go back to file lets say we want to add new config after test_workers so

this

  test_workers: {
    enabled: true
  },

  test_settings: {
    default: {

becomes

  test_workers: {
    enabled: true
  },

  "@nightwatch/apitesting" : {
    "log_responses": true
  },

  test_settings: {
    default: {
