Integrate Your Test Suite

BrowserStack’s Node SDK supports a plug-and-play integration with the Cucumber Runner. Run your entire test suite in parallel with a few steps!

This guide will help you:

  1. Install the Node SDK
  2. Create your BrowserStack config file
  3. Setup advanced features and use cases

Set BrowserStack credentials

Saving your BrowserStack credentials as environment variables makes it easy to run your test suite from your local or CI environment.

# Set these values in your ~/.zprofile (zsh) or ~/.profile (bash)
export BROWSERSTACK_USERNAME="YOUR_USERNAME"
export BROWSERSTACK_ACCESS_KEY="YOUR_ACCESS_KEY"
# setx.exe does not set the environment variable in the current command prompt, but it will be available in subsequent command prompts
setx BROWSERSTACK_USERNAME "YOUR_USERNAME"
setx BROWSERSTACK_ACCESS_KEY "YOUR_ACCESS_KEY"

# Verify whether the variables have been set
echo BROWSERSTACK_USERNAME
echo BROWSERSTACK_ACCESS_KEY

Install BrowserStack Node SDK

Using the BrowserStack Node SDK ensures a plug-and-play integration. It handles webdriver management, runs tests in parallel with different strategies, and configures other BrowserStack features under the hood without requiring any code changes.

# Install using npm
npm i browserstack-node-sdk@latest

"dependencies": {
  "browserstack-node-sdk": "^1",
}

Add the BrowserStack runner command

Add the following task in the scripts section in your package.json file.

package.json

Remember to replace [args] with the with the current cucumber args you may have.

Create your BrowserStack config file

The browerstack.yml file holds all the required capabilities to run your tests on BrowserStack.

Set access credentials

Set userName and accessKey as environment variables or use them directly in the config file.

Set platforms to test on

Set the browsers / devices you want to test under the platforms object. Our config follows W3C formatted capabilities.

Parallel thread #1
Parallel thread #2
Parallel thread #3

Set number of parallels threads per platform

The parallelsPerPlatform property determines the number of parallel threads to be executed. BrowserStack’s SDK runner will select the best strategy based on the configured value.

Example 1: If you have configured 3 platforms and set parallelsPerPlatform as 2: a total of 6 (2 x 3) parallel threads will be used on BrowserStack.

Example 2: If you have configured 1 platform and set parallelsPerPlatform as 15: a total of 15 (1 x 15) parallel threads will be used on BrowserStack.

Enable BrowserStack Local

Test localhost / internal servers in your network

True
False
Test Localhost / Staging websites that are not publicly accessible

BrowserStack’s Local Testing feature connects with test suites pointing to your localhost URL

Learn more

If your staging environment is behind a proxy or firewall, additional arguments, such as proxy username, proxy password, etc, need to be set. Check out Local Binary parameters to learn about additional arguments or Contact Support for assistance.

Organizing your test suite

Our projectName, buildName, and name capabilities help with organizing your tests on BrowserStack’s Dashboard.

Build Name
Project Name

name is the name of your test sessions and is automatically picked from your test class/spec name. It doesn’t need to be set manually when using the BrowserStack SDK.

Use additional debugging features

By default, BrowserStack provides prettified session logs, screenshots on every failed selenium command, and a video of the entire test. Additionally, you can enable the following features:

Visual logs

Enables screenshots for every selenium command ran

True
False
Network logs

Enables network capture for the session in HAR format. Reduces session performance slightly

True
False

Create BrowserStack Config file

Copy the adjacent code snippet and create browserstack.yml in the root folder of your test suite.

Advanced features and use cases

Here’s a list of features and capabilities that you might find useful:

Accept insecure certificates

This capability suppresses browser popups warning about self-signed certificates usually found in staging environments. Add the following property to your browserstack.yml file.

Capability Expected values
acceptSslCerts A boolean. Default is False.
True if you want to accept all SSL certificates.

Change desktop resolution

Add this capability to your browserstack.yml to change the default desktop screen resolution for your tests on BrowserStack.

Capability Description Expected values
resolution Set the resolution of your VM before beginning your test A string. Default resolution is 1024x768

Supported resolutions:
Windows (XP, 7): 800x600, 1024x768, 1280x800, 1280x1024, 1366x768, 1440x900, 1680x1050, 1600x1200, 1920x1200, 1920x1080 and 2048x1536
