TestNG is a testing framework designed to simplify a broad range of testing needs, from unit testing (testing a class in isolation of the others) to integration testing (testing entire systems made of several classes, several packages and even several external frameworks, such as application servers). Cucumber is a software tool that supports behavior-driven development (BDD).
This BrowserStack Example repository demonstrates a Selenium test framework written in Cucumber and TestNG with parallel testing capabilties. 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, docker and BrowserStack using various run configurations and test capabilities.

- Gradle >= 5.0+
Maven:
mvn install
Gradle:
gradle build
This repository contains the following Selenium tests:
| Module | Test name | Description |
|---|---|---|
| E2E | End to End Scenario | 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 with given username | This test verifies the login workflow with different types of valid login users. |
| Login | Login as Locked User | This test verifies the login workflow error for a locked user. |
| Offers | Offers for Mumbai location | This test mocks the GPS location for Mumbai and verifies that the product offers applicable for the Mumbai location are shown. |
| Product | Apply Apple Vendor Filter | This test verifies that 9 Apple products are only shown if the Apple vendor filter option is applied. |
| Product | Apply Lowest to Highest Order By | This test verifies that the product prices are in ascending order when the product sort "Lowest to Highest" is applied. |
| User | Login as User with no image loaded | This test verifies that the product images load for user: "image_not_loading_user" on the e-commerce application. Since the images do not load, the test case assertion fails. |
| User | Login as User with existing Orders | This test verifies that existing orders are shown for user: "existing_orders_user" |
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 browserstack.yml file.
Note:
- We have configured a list of test capabilities in the browserstack.yml file. You can certainly update them based on your device / browser test requirements.
- The exact test capability values can be easily identified using the Browserstack Capability Generator
In this section, we will run a single test on Chrome browser on Browserstack. To change test capabilities for this configuration, please refer to the browserstack-single.yml file.
-
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:
Maven:
mvn test -P bstack-single -Dbrowserstack.config="./src/test/resources/conf/browserstack-single.yml"
Gradle:
gradle clean bstack-single -Dbrowserstack.config="./src/test/resources/conf/browserstack-single.yml"To run a specific test scenario, use the following command with the additional 'test-name' argument:
Maven:
mvn test -P bstack-single -Dbrowserstack.config="./src/test/resources/conf/browserstack-single.yml" -Dtest-name="<Test scenario name>"
Gradle:
gradle clean bstack-single -Dbrowserstack.config="./src/test/resources/conf/browserstack-single.yml" -Dtest-name="<Test scenario name>"
where, the argument 'test-name' can be any Cucumber scenario name configured in this repository.
E.g. "Login as username", "Login as Locked User", "Offers for mumbai geo-location" or any of the other test scenario names, as outlined in About the tests in this repository section.

Output
This run profile executes a single test on a single browser on BrowserStack. Please refer to your BrowserStack dashboard for test results.
In this section, we will run the tests in parallel on a single browser on Browserstack. Refer to browserstack-parallel.yml 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 browser, use the following command:
Maven:
mvn test -P bstack-parallel -Dbrowserstack.config="./src/test/resources/conf/browserstack-parallel.yml"
Gradle:
gradle clean bstack-parallel -Dbrowserstack.config="./src/test/resources/conf/browserstack-parallel.yml" -
Output
This run profile executes the entire test suite in parallel on a single BrowserStack browser. Please refer to your BrowserStack dashboard for test results.
In this section, we will run the tests in parallel on multiple browsers on Browserstack. Refer to the browserstack-parallel-browsers.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, use the following command:

[Web application hosted on internal environment] Running your tests on BrowserStack using BrowserStackLocal
-
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-local.ymlfile 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).
