This BrowserStack Example repository demonstrates a Selenium 4 Page Factory Model wrapped under Cucumber and TestNG with parallel testing capabilities. The Selenium test scripts are written for the open source BrowserStack Demo web application (Github). This BrowserStack Demo App is an e-commerce web application which showcases multiple real-world user scenarios, written in Next and React. 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 Selenium tests are run on different platforms like on-prem and BrowserStack using various run configurations and test capabilities.

🌐 Empowered to run on various platforms including on-premise browsers, browsers running on a remote selenium grid such as BrowserStack Automate

🚀 Enables concurrent execution of cucumber scenarios at scenario and feature level across different platforms.

💡 Run the builds with max concurrency as per the parallel quota on your BrowserStack Account.

💻 Control concurrency of the tests by setting thread count from terminal.

✅ Three distinct layers of framework implementaion viz. Feature File, Step Definitions, Page Factory Classes to maintain the border between Business users and developers.

♻️ Can be ran on any installed browsers onprem without downloading the respective driver executables.

⚡ Single Runner class required to configure all parameters and plugins.

• Clone the repository

• Ensure you have the following dependencies installed on the machine

  • Java >= 8
  • Maven >= 3.1+

  Maven:

  mvn install

This repository contains the following Cucumber Scenario tests:

• @test will run all scenarios in Offers feature file.
• @users will run all scenarios in Users feature file.
• @e2e will run all scenarios in E2E feature file.
• @regression will run all scenarios in all the feature files.

• On-premise/self-hosted
• BrowserStack

For all the parallel run configuration profiles, tests will run with max parallels in your BrowserStack account, or you can configure the parallel test threads from the browserstack.yml file

• Extent reports
• Reports in HTML and PDF formats are generated in the Reports with TimeStamp.

This infrastructure points to running the tests on your own machine using any browser (e.g. Chrome) using the browser's driver executables (e.g. ChromeDriver for Chrome). This driver dependency is resolved using the WebDriverManager and eliminates the need to download the webdriver on the local machine.

• How to run the test?

  To run any test scenario (e.g. End to End Scenario) on your own machine, use the following command, you can specify any cucumber tag from the feature files to run the scenarios at feature/scenario outline level in this Maven Profile.

  Eg. "@e2e", "@noimage", "@offers" or any of the other test scenario tags, as outlined in About the tests in this repository section. "-Dcucumber.filter.tags=@e2e"

  User can also specify the choice of browser in the <browser-type> tags of the profile to run the suite/scenarios in that browser. Eg. <browser-type>firefox</browser-type>

  thread-count can be set for the tests from the terminal "-DthreadCount=5"

  Maven:

  mvn test -P scenario-onprem

• Output

  This run profile executes a specific test scenario/suite in single/parallel on the stated browser instance on your own machine.

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.

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

• Identify your BrowserStack username and access key from the BrowserStack 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 respective file:

  • browserstack.yml file

Note:

• We have configured a list of test capabilities in the json files. You can certainly update them based on your device / browser test requirements.
• The exact test capability values can be easily identified using the Browserstack W3C Capability Generator

In this section, we will run the tests in parallel on a single browser on Browserstack. Refer to browserstack.yml file to change test capabilities for this configuration.

• How to run the test?

  To run the tests in parallel on a single BrowserStack browser, use the following command:

  Maven:

  mvn test -P scenario-bs

  You can mention any scenario from the feature files using the -Dcucumber.filter.tags, tags defined at Feature level Eg. @users will run all the scenarios in the Users Feature file in parallel. Likewise @regression will run all the scenarios from all the Feature files in parallel.

• Output

  This run profile executes any scenario/entire test suite in parallel on a single BrowserStack browser. Please refer to your BrowserStack dashboard for test results.

  • Note: By default, this execution would run maximum test threads based on the parallel quota on your BrowserStack Account. Thread count can be configured as below based on your requirements.

  mvn test -P scenario-bs "-Dcucumber.filter.tags=@regresssion"

In this section, we will run the tests in parallel on multiple browsers on Browserstack. Refer to the browserstack.yml file to change test capabilities for this configuration.

• How to run the test?

  To run the entire test suite in parallel on multiple BrowserStack browsers/devices, use the following command:

  Maven:

  mvn test -P scenario-bs

  You can mention any scenario from the feature files using the -Dcucumber.filter.tags, tags defined at Feature level Eg. @users will run all the scenarios in the Users Feature file in parallel. Likewise @regression will run all the scenarios from all the Feature files in parallel across multiple browsers/devices.

• 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.

• In this section, we will run a single test case to test the BrowserStack Demo app hosted on your local machine i.e. localhost. Refer to the browserstack.yml 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:

  • Local Testing with Automate
  • BrowserStackLocal Java GitHub

• How to run the test?

  • To run any test scenario (e.g. End to End Scenario) on a single BrowserStack browser using BrowserStackLocal, use the following command:

  Maven:

  mvn test -P local-bs

You can mention any scenario from the feature files using the -Dcucumber.filter.tags, tags defined at Feature level Eg. @users will run all the scenarios in the Users Feature file in parallel. Likewise @regression will run all the scenarios from all the Feature files in parallel.

• Output

  This run profile executes a single test/entire suite on an internally hosted web application on a single browser on BrowserStack in parallel. Please refer to your BrowserStack dashboard for test results.

In this section, we will run the test cases to test the internally hosted website in parallel on multiple browsers/devices on Browserstack. Refer to the browserstack.yml file to change test capabilities for this configuration.

• How to run the test?

  To run the entire test suite in parallel on multiple devices and browsers using BrowserStackLocal, use the following command:

  Maven:

  mvn test -P local-bs

• Output

  This run profile executes the entire test suite on an internally hosted web application on multiple browsers on BrowserStack. Please refer to your BrowserStack dashboard for test results.

• Note: By default, this execution would run maximum test threads based on the parallel quota on your BrowserStack Account. Thread count can be configured as below based on your requirements.

  mvn test -P local-bs "-Dcucumber.filter.tags=@e2e"
