Introduction

WebdriverIO is a progressive automation framework built to automate modern web and mobile applications. It simplifies the interaction with your app and provides a set of plugins that help you create a scalable, robust and flakiness test suite.

This BrowserStack Example repository demonstrates a WebdriverIO tests framework written in Mocha and nodeJS with parallel testing capabilities. The WebdriverIO test scripts are written for the open source Browserstack Demo App.This BrowserStack Demo Mobile App is an e-commerce mobile application which showcases multiple real-world user scenarios. The app is bundled with offers data, orders data and products data that contains everything you need to start using the app and run tests out-of-the-box.

The WebDriverIO tests are run on different platforms like on-prem and BrowserStack using various run configurations and test capabilities.

Repository setup

  • Clone the repository

  • Ensure you have the following dependencies installed on the machine

    • NodeJS >= 16.11.1 (includes npm 8.0.0)

  • Run below command to configure dependencies

    npm install

About the tests in this repository

This repository contains the following WebdriverIO tests:

Module Test name Description
E2E e2e.spec.js This test scenario verifies successful product purchase lifecycle end-to-end. It demonstrates the Page Object Model design pattern and is also the default test executed in all the single test run profiles.
Login login.spec.js This test verifies the login workflow with different types of valid login users.
Login login_data_driven.spec.js This test verifies the login for all error cases in a datadriven way
Login login_requested.spec.js This test verifies that the login page is shown when you access the favourites page with being logged in
Offers offers.spec.js This test mocks the GPS location for Singapore and verifies that the product offers applicable for the Singapore location are shown.
User user.spec.js The first test verifies that existing orders are shown for user: "existing_orders_user". The second test verifies if a user can add product to the favourites.

Test infrastructure environments

Configuring the maximum parallel test threads for this repository

For all the parallel run configuration profiles, you can configure the maximum parallel test threads by changing the settings below.

  • BrowserStack

    resources/conf/wdio-bstack-parallel.conf.js

    capabilities: [{
maxInstances: 5,
...

Test Reporting

On Premise / Self Hosted

This infrastructure points to running the tests on your own machine using simulator or connected devices.

Prerequisites

  • For this infrastructure configuration (i.e on-premise), ensure that the app is downloaded and placed in the /bin folder.

Running Your Tests

Run a specific test on your own machine

  • How to run the test?

    To run the default test scenario (e.g. End to End Scenario) on your own machine, use the following command:

    npm run onprem

    To run a specific test scenario, use the following command with the additional 'spec' argument:

    npm run onprem-suite -- -- spec orders

Run the entire test suite on your own machine

  • How to run the test?

    To run the entire test suite on your own machine, use the following command:

    npm run onprem-suite

BrowserStack

BrowserStack provides instant access to 2,000+ real mobile devices and browsers on a highly reliable cloud infrastructure that effortlessly scales as testing needs grow.

Prerequisites

  • Create a new BrowserStack account or use an existing one.

  • Identify your BrowserStack username and access key from the BrowserStack App Automate Dashboard and export them as environment variables using the below commands.

    • For *nix based and Mac machines:

      export BROWSERSTACK_USERNAME=<browserstack-username> &&
export BROWSERSTACK_ACCESS_KEY=<browserstack-access-key>

    • For Windows:

      set BROWSERSTACK_USERNAME=<browserstack-username>
set BROWSERSTACK_ACCESS_KEY=<browserstack-access-key>

Alternatively, you can also hardcode username and access_key objects in the wdio*.conf.js files.

Note:

  • We have configured the capabilities in wdio*.conf.js files. You can certainly update them based on your device test requirements.
  • The exact test capability values can be easily identified using the Browserstack Capability Generator

Running Your Tests on BrowserStack

Prerequisites

You need to upload the APK or IPA to BrowserStack, before you can run the test on BrowserStack. BrowserStack will provide you with an app_url which you need to use.

You can upload the APK or IPA using a file on your filesystem or using a public url.

cURL command:

curl -u "browserstack_username:browserstack_access_key" \
-X POST "https://api-cloud.browserstack.com/app-automate/upload" \
-F "file=@/path/to/ipa/or/apk" \
-F "custom_id=BrowserStackDemoApp"

More information on Upload apps from filesystem, Upload apps using public URL or Define custom ID for app.

Run a specific test on BrowserStack

In this section, we will run a single test on an Android device on Browserstack. To change test capabilities for this configuration, please refer to the capabilities object in resources/conf/wdio-bstack-single.conf.js file.

  • How to run the test?

    • To run the default test scenario (e.g. End to End Scenario) on a BrowserStack device, use the following command: 
      npm run bstack-single
    • To run a specific test scenario, use the following command with the additional 'spec' argument: 
      npm run bstack-suite -- -- spec orders

Run the entire test suite in parallel on a single BrowserStack device

In this section, we will run the tests in parallel on a single device on Browserstack. Refer to capabilities object in resources/conf/wdio-bstack-parallel.conf.js file to change test capabilities for this configuration.

  • How to run the test?

    • To run the entire test suite in parallel on a single BrowserStack device type, use the following command: 
      npm run bstack-parallel

Note: By default, this execution would run maximum 2 test threads in parallel on BrowserStack. The parallels can eb modified by updated the maxInstances inside capabilities object in resources/conf/wdio-bstack-parallel.conf.js.

Run the entire test suite in parallel on multiple BrowserStack devices

In this section, we will run the tests in parallel on multiple devices on Browserstack. Refer to the capabilities object in resources/conf/wdio-bstack-parallel-devices.conf.js file to change test capabilities for this configuration.

  • How to run the test?

    • To run the entire test suite in parallel on multiple BrowserStack devices, use the following command: 
      npm run bstack-parallel-devices

Mobile application using local or internal environment - Running your tests on BrowserStack using BrowserStackLocal

Prerequisites

  • Clone the BrowserStack demo application repository.

    git clone https://github.com/browserstack/browserstack-demo-app

  • Please follow the README.md on the BrowserStack demo application repository to install and start the dev server on localhost.

  • We will change the response of the signin (for the locked_user) API endpoint. (File to change: pages/api/signin.js line 43)

    • The API endpoint respond with a specific error, Your account has been locked..
    • We will change that to something generic, like: Something went wrong.

  • In this section, we will run a single test case that changes the API used in BrowserStack Demo app, in a wat that it interact with you local machine. Refer to the capabilities object in resources/conf/wdio-bstack-local.conf.js file to change test capabilities for this configuration.

  • Note: You may need to provide additional BrowserStackLocal arguments to successfully connect your localhost environment with BrowserStack infrastructure. (e.g if you are behind firewalls, proxy or VPN).

  • Further details for successfully creating a BrowserStackLocal connection can be found here:

Mobile application using local or internal environment - Run a specific test on BrowserStack using BrowserStackLocal

  • How to run the test?

    • To run the default test scenario (e.g. End to End Scenario) on a single BrowserStack device using BrowserStackLocal, use the following command: 
      npm run bstack-local

Mobile application using local or internal environment - Run the entire test suite in parallel on multiple BrowserStack devices using BrowserStackLocal

In this section, we will run the test cases on a mobile application using a local or internal environment in parallel on multiple devices on Browserstack. Refer to the capabilities object in resources/conf/wdio-bstack-local-parallel-devices.conf.js file to change test capabilities for this configuration.

  • How to run the test?
