e2e test

using

Nightwatch.js

Travel Systems CX
Roto

what is this?

Architecture

need to know

  • concept of e2e test
  • CSS Selector or Xpath Selector
  • javascript & node.js

good point

  • easy to write tests
  • javascript & node.js
  • custom test report
  • and many more..

Setup

we will install these.

node.js

project initialize

  • run this command from shell.
mkdir nightwatch-start
cd nightwatch-start
npm init -y
npm install --save-dev nightwatch
mkdir tools
mkdir tests

download
selenium standalone

server

download
chrome web driver

nightwatch.json

{
  "src_folders" : ["tests"],
  "output_folder" : "reports",
  "custom_commands_path" : "",
  "custom_assertions_path" : "",
  "page_objects_path" : "",
  "globals_path" : "",

  "selenium" : {
    "start_process" : true,
    "server_path" : "./tools/selenium-server-standalone-3.0.1.jar",
    "port" : 4444,
    "cli_args" : {
      "webdriver.chrome.driver" : "./tools/chromedriver"
    }
  },

  "test_settings" : {
    "default" : {
      "launch_url" : "http://localhost",
      "selenium_port"  : 4444,
      "selenium_host"  : "localhost",
      "silent": true,
      "screenshots" : {
        "enabled" : false,
        "path" : ""
      },
      "desiredCapabilities": {
        "browserName": "chrome",
        "marionette": true
      }
    },

    "chrome" : {
      "desiredCapabilities": {
        "browserName": "chrome"
      }
    }
  }
}

write test script

module.exports = {
  'coupang travel test' : (client) => {
    client
      .url('http://www.coupang.com/np/categories/91018')
      .waitForElementVisible('#contents', 1000)
      .assert.title('쿠팡!')
      .assert.visible('#product-list')
      .end();
  }
};

Run nightwatch!

node node_modules/nightwatch/bin/nightwatch

  ... 
  "selenium" : {
    ...
    "cli_args" : {
      ...
      "webdriver.gecko.driver" : "./tools/geckodriver"
  },
  ...
  "test_settings" : {
    ...
    "firefox" : {
      "desiredCapabilities": {
        "browserName": "firefox",
        "javascriptEnabled": true,
        "acceptSslCerts": true
      }
    }
  }

Run with Phantomjs

  • install phantomjs-prebuilt

     
  • edit nightwatch.json
{
  ...
  "test_settings" : {
    ...
    "phantomjs" : {
      "desiredCapabilities": {
        "browserName": "phantomjs",
        "javascriptEnabled": true,
        "acceptSslCerts": true,
        "phantomjs.binary.path": "./node_modules/phantomjs-prebuilt/bin/phantomjs"
      }
    }
  }
npm install --save-dev phantomjs-prebuilt

Assertion

Assert / Verify

client
  .url('http://www.google.com')
  .waitForElementVisible('body', 1000)
  .assert.title('Google')
  .assert.visible('input[type=text]')
  .setValue('input[type=text]', 'rembrandt van rijn')
  .waitForElementVisible('button[name=btnG]', 1000)
  .click('button[name=btnG]')
  .pause(1000)
  .assert.containsText('ol#rso li:first-child', 'Rembrandt - Wikipedia')
  .end();

BDD Style Assertions

this.demoTest = function (browser) {
  // start with identifying the element
  // and then assert the element is present
  browser.expect.element('#main').to.be.present;

  // or assert the element is visible
  browser.expect.element('#main').to.be.visible;
};

webdriver-manager

  • angular sub project
  • managing web driver install
// install module
npm install --save-dev webdriver-manager

// install gecko web driver
node ./node_modules/webdriver-manager/bin/webdriver-manager update 

// with chrome web driver
node ./node_modules/webdriver-manager/bin/webdriver-manager update --chrome

Booking web use case

Simple UI Test

  • Home
  • TLP
  • TDP

Full Integration Test

  1. TDP
  2. Login
  3. TDP
  4. Booking Sheet
  5. Ordder Page

Jenkins Integration

If test fails

Todo

  • ie test environment
    (from will's desktop)
  • DDP e2e test
  • Upgrade custom report
