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.

Clone the repository
-
For this infrastructure configuration (i.e on-premise) ensure that the ChromeDriver executable is placed in the
/src/test/resources/folder. -
Ensure you have the following dependencies installed on the machine
- Java >= 8
- Maven >= 3.1+
- Gradle >= 5.0+
Maven:
mvn install
Gradle:
./gradlew 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" |
For all the parallel run configuration profiles, you can configure the maximum parallel test threads by changing the settings below.
-
Docker
NODE_MAX_INSTANCES = 5 GRID_MAX_SESSION = 5
-
BrowserStack
-
Maven:
parallel-count = 5
-
This infrastructure points to running the tests on your own machine using a browser (e.g. Chrome) using the browser's driver executables (e.g. ChromeDriver for Chrome). Selenium enables this functionality using WebDriver for many popular browsers.
- For this infrastructure configuration (i.e on-premise) ensure that the ChromeDriver executable is placed in the
/src/test/resources/folder.
Note: The ChromeDriver version must match the Chrome browser version on your 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:
Maven:
mvn test -P on-premGradle:
./gradlew on-prem
To run a specific test scenario, use the following command with the additional 'test-name' argument:
Maven:
mvn test -P on-prem -Dtest-name="<Test scenario name>"
Gradle:
./gradlew on-prem -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 specific test scenario on a single browser instance on your own machine.
-
How to run the test?
To run the entire test suite on your own machine, use the following command:
Maven:
mvn test -P on-prem-suiteGradle:
./gradlew on-prem-suite
-
Output
This run profile executes the entire test suite sequentially on a single browser, on your own machine.
Docker is an open source platform that provides the ability to package and test applications in an isolated environment called containers.
- Install and start Docker.
- Note: Docker should be running on the test machine. Ensure Docker Compose is installed as well.
- Run
docker-compose pullfrom the current directory of the repository.
-
How to run the test?
- Start the Docker by running the following command:
docker-compose up -d
- To run the default test scenario (e.g. End to End Scenario) on your own machine, use the following command:
Maven:
mvn test -P dockerGradle:
./gradlew docker
To run a specific test scenario, use the following command with the additional 'test-name' argument:
Maven:
mvn test -P docker -Dtest-name="<Test scenario name>"
Gradle:

-
After tests are complete, you can stop the Docker by running the following command:
docker-compose down
-
Output
This run profile executes a specific test scenario on a single browser deployed on a docker image.
-
How to run the test?
- Start the docker image first by running the following command:
docker-compose up -d
- To run the entire test suite in parallel on the docker image, use the following command:
Maven:
mvn test -P docker-parallelGradle:
./gradlew docker-parallel
- After the tests are complete stop the Selenium grid by running the following command:
docker-compose down
-
Output
This run profile executes the entire test suite in parallel on a single browser, deployed on a docker image.
-
Note: By default, this execution would run maximum 5 test threads in parallel on Docker. Refer to the section "Configuring the maximum parallel test threads for this repository" for updating the parallel thread count based on your requirements.
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 bs.json file.
Note:
- We have configured a list of test capabilities in the bs.json file. You can certainly update them based on your device / browser test requirements.
