Integrate Your Test Suite
Integrate BrowserStack into your test suite using the BrowserStack Node SDK — a plug-and-play solution that takes care of all the integration steps for you!
Integration steps
Install BrowserStack Node SDK
Install the BrowserStack SDK using npm for your MochaJS based test suite for plug-and-play integration with BrowserStack.
The npx setup command generates a browserstack.yml file at the root location of your project with your access credentials already configured. It also adds new command(s) in your package.json file to run tests on BrowserStack.
You can also set your credentials using the environment variables BROWSERSTACK_USERNAME and BROWSERSTACK_ACCESS_KEY.
Configure your browserstack.yml file
The auto-generated browserstack.yml file situated in the root location of your project holds all the required settings to run tests on BrowserStack.
Set platforms to test on
Set the browsers and devices you want to test under the platforms object. Our config follows W3C formatted capabilities.
Set number of parallel threads per platform
The parallelsPerPlatform property determines the number of parallel threads to be executed. BrowserStack’s SDK runner selects 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 are 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 are used on BrowserStack.
Configure BrowserStack Local
Test localhost / internal servers in your network
BrowserStack’s Local Testing feature connects with test suites pointing to your localhost URL
If your staging environment is behind a proxy or firewall, you need to set additional arguments, such as proxy username, proxy password, etc. Check out Local Binary parameters to learn about additional arguments or Contact Support for assistance.
BrowserStack Reporting
You can leverage BrowserStack’s extensive reporting features using the following capabilities:
Set build name as the name of the job/test suite being run
| buildIdentifier | Description | Generated build name on BrowserStack dashboard |
|---|---|---|
| ${BUILD_NUMBER} (Default) | If build is triggered locally, an incremental counter is appended. If build is triggered with CI tools, CI generated build number is appended. |
bstack-demo 1 bstack-demo CI 1395 |
| ${DATE_TIME} | The timestamp of run time is appended to the build. | bstack-demo 29-Nov-20:44 |
Advanced use cases for Build name
Custom formatting of build name
Prefix buildIdentifier with desired characters, for example, # or :
buildName: bstack-demo
buildIdentifier: '#${BUILD_NUMBER}'
Re-run tests in a build
You can re-run selected tests from a build using any of the following options:
Option 1: Set the existing build name in the BROWSERSTACK_BUILD_NAME variable and prepend it to your test run command to re-run tests in the same build:
MacOS/Linux:
BROWSERSTACK_BUILD_NAME="bstack-demo 123" npm run sample-test
Windows Powershell:
$env:BROWSERSTACK_BUILD_NAME=“bstack-demo 123”; npm run sample-test
Windows cmd:
set BROWSERSTACK_BUILD_NAME=“bstack-demo 123” && npm run sample-test
Option 2: Set the build name as a combination of buildName and buildIdentifier, as seen on the dashboard, and set buildIdenitifier as null:
buildName: bstack-demo 123
buildIdentifier: null
Option 3: Set the buildIdentifier as the build number or time of the required build as seen on the dashboard:
buildName: bstack-demo
buildIdentifier: 123
Set a project name for your project.
sessionName of your test sessions are be automatically picked from your test class/spec name. You do not need to set it 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:
Update BrowserStack Config file
Copy the given config into your browserstack.yml file.
Run your test suite on BrowserStack
Your test suite is now ready to run on BrowserStack! Run the commands added under the scripts property section in the package.json file. Here is an example command:
If you don’t see any new commands, make sure you ran npx setup correctly or contact support for assistance.
Advanced features and use cases
Here’s a list of features and capabilities that you might find useful:
Accept insecure certificates
The acceptInsecureCerts capability suppresses browser popups warning about self-signed certificates usually found in staging environments.
| Capability | Expected values |
|---|---|
acceptInsecureCerts |
A boolean. Default is False.True if you want to accept all SSL certificates. |
Change desktop resolution
The resolution capability changes the default desktop screen resolution for your tests on BrowserStack infrastructure.
| 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): 800x600, 1024x768, 1280x800, 1280x1024, 1366x768, 1440x900, 1680x1050, 1600x1200, 1920x1200, 1920x1080, 2048x1536, 2560x1600, and 2560x1920 Windows (7): 800x600, 1024x768, 1280x800, 1280x1024, 1366x768, 1440x900, 1680x1050, 1600x1200, 1920x1200, 1920x1080, 2048x1536, 2560x1600, 2560x1920, and 3840x2160 Windows (8, 8.1, 10, 11): 1024x768, 1280x800, 1280x1024, 1366x768, 1440x900, 1680x1050, 1600x1200, 1920x1200, 1920x1080, 2048x1536, 2560x1600, 2560x1920, and 3840x2160 OS X (Sonoma, Ventura, Monterey, Big Sur, Catalina, Mojave, and High Sierra): 1024x768, 1280x960, 1280x1024, 1600x1200, 1920x1080, 2560x1440, 2560x1600, and 3840x2160 OS X (All other versions): 1024x768, 1280x960, 1280x1024, 1600x1200, and 1920x1080
