Medium Article

Please do checkout my medium article which would give you more insight on this setup. protractor-cucumber-typescript(Medium)

Features

No typings.json or typings folder, they have been replaced by better '@types' modules in package.json.
ts-node(typescript execution environment for node) in cucumberOpts.
All scripts written with > Typescript2.0 & Cucumber2.0.
Neat folder structures with transpiled js files in separate output folder.
Page Object design pattern implementation.
Extensive hooks implemented for BeforeFeature, AfterScenarios etc.
Screenshots on failure feature scenarios.

To Get Started

Pre-requisites

1.NodeJS installed globally in the system. https://nodejs.org/en/download/

2.Chrome or Firefox browsers installed.

3.Text Editor(Optional) installed-->Sublime/Visual Studio Code/Brackets.

Setup Scripts

Clone the repository into a folder
Go inside the folder and run following command from terminal/command prompt

npm install

All the dependencies from package.json and ambient typings would be installed in node_modules folder.

Run Scripts

First step is to fire up the selenium server which could be done in many ways, webdriver-manager proves very handy for this.The below command should download the chrome & gecko driver binaries locally for you!

npm run webdriver-update

Then you should start your selenium server!

npm run webdriver-start

The below command would create an output folder named 'typeScript' and transpile the .ts files to .js.

npm run build

Now just run the test command which launches the Chrome Browser and runs the scripts.

npm test

Writing Features

Feature: To search typescript in google
@TypeScriptScenario

  Scenario: Typescript Google Search
    Given I am on google page
    When I type "Typescript"
    Then I click on search button
    Then I clear the search text

Writing Step Definitions

import { browser } from "protractor";
import { SearchPageObject } from "../pages/searchPage";
const { Given } = require("cucumber");
const chai = require("chai").use(require("chai-as-promised"));
const expect = chai.expect;

const search: SearchPageObject = new SearchPageObject();

Given(/^I am on google page$/, async () => {
    await expect(browser.getTitle()).to.eventually.equal("Google");
});

Writing Page Objects

import { $ } from "protractor";

export class SearchPageObject {
    public searchTextBox: any;
    public searchButton: any;

    constructor() {
        this.searchTextBox = $("#lst-ib");
        this.searchButton = $("input[value='Google Search']");
    }
}

Cucumber Hooks

Following method takes screenshot on failure of each scenario

After(async function(scenario) {
    if (scenario.result.status === Status.FAILED) {
        // screenShot is a base-64 encoded PNG
         const screenShot = await browser.takeScreenshot();
         this.attach(screenShot, "image/png");
    }
});

CucumberOpts Tags

Following configuration shows to call specific tags from feature files

cucumberOpts: {
    compiler: "ts:ts-node/register",
    format: "json:./reports/json/cucumber_report.json",
    require: ["../../stepdefinitions/*.ts", "../../support/*.ts"],
    strict: true,
    tags: "@TypeScriptScenario or @CucumberScenario or @ProtractorScenario",
},

HTML Reports

Currently this project has been integrated with cucumber-html-reporter, which is generated in the reports folder when you run npm test. They can be customized according to user's specific needs.
