Integrate Your Test Suite with BrowserStack

This section will help you migrate your existing test suite to run on BrowserStack Automate. It also covers key features and best practice recommendations for smooth integration.

Select your integration method

  • BrowserStack SDK (Recommended)
    Plug-n-play solution that takes care of all the integration steps for you
  • Legacy integration
    Perform the integration steps yourself. Useful for custom frameworks and advanced use-cases

Using the BrowserStack SDK is the recommended integration method for NodeJS. The SDK handles your integration steps automatically. Use the Manual integration only when you are using custom frameworks or want to handle advanced parallelization use-cases.

Setup authentication

Set environment variables for BrowserStack credentials

In the run a sample build section, we set up BrowserStack credentials directly in the test script.

That method works for a sample build, but for a production-grade integration we recommend you store your credentials as environment variables and use those environment variables in your code.

Copy 
export BROWSERSTACK_USERNAME="YOUR_USERNAME"
export BROWSERSTACK_ACCESS_KEY="YOUR_ACCESS_KEY"

$env:BROWSERSTACK_USERNAME "YOUR_USERNAME" 
$env:BROWSERSTACK_ACCESS_KEY "YOUR_ACCESS_KEY" 

setx BROWSERSTACK_USERNAME "YOUR_USERNAME" 
setx BROWSERSTACK_ACCESS_KEY "YOUR_ACCESS_KEY" 

set BROWSERSTACK_USERNAME=YOUR_USERNAME
set BROWSERSTACK_ACCESS_KEY=YOUR_ACCESS_KEY

Connect CDP Endpoint

Connect to the CDP endpoint at BrowserStack as shown in the following example:

Connect your website under test

BrowserStack can integrate with test suites pointing to your localhost URL, staging environment and even websites behind one or more proxies/firewalls.

  • NPM - Language Bindings
  • CLI Interface - Binary

Install the package

Add browserstack-local to your project using the following npm command:

Copy icon Copy

Set the access key and use available methods in your test script

Set the bs_local_args variable to your BrowserStack Access key and and use the following methods provided by the local library to manage your local connection:

Method Description
bs_local.start() Expects bs_local object. Returns a callback when the tunnel has started successfully. Your test script should start executing after this callback has been invoked.
bs_local.stop() Call this method after your test suite is complete.
bs_local.isRunning() Check if BrowserStack local instance is running.

Use the following example code snippet to manage your local connections:

Run a test using BrowserStack Local

Try running a localhost after completing the above steps. Check out our sample Git repository for more details.

Download BrowserStack Local

Show download options

Unzip the binary

Unzip the downloaded file and move it to a folder/directory from which you have permission to start it using your command line or terminal.

Run the binary using your command line or terminal

Run the following command to initiate the BrowserStack Local connection

Copy 
# Step 3 - Run this command in your terminal to start the BrowserStack Local binary. Your working directory should be where you have the downloaded binary.
./BrowserStackLocal --key YOUR_ACCESS_KEY

# Step 3 - Run this command in your terminal to start the BrowserStack Local binary. Your working directory should be where you have the downloaded binary.
./BrowserStackLocal --key YOUR_ACCESS_KEY

# Step 3 - Run this command in your command prompt. Your working directory should be where you have unzipped BrowserStackLocal.exe
BrowserStackLocal.exe --key YOUR_ACCESS_KEY

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.

Migrate your test cases

This section will help you with all the config changes, commonly used features, and best practices for a smooth migration of your test cases to BrowserStack.

Set OS-browser combination to run test

We recommend running your build using a single browser like Chrome or Firefox to begin with. This will isolate issues during the migration phase and help with faster debugging. Refer the capabilities as shown to use Chrome. Once you’ve migrated your test cases or have achieved stability with Chrome or Firefox, you can set up cross-browser testing.

Organize tests

Use the following capabilities for naming your tests and builds. This ensures effective debugging, test reporting, and build execution time analysis.

Capability Description
name Name for your test case. For example, Homepage - Get started
build CI/CD job or build name. For example, Website build #23, staging_1.3.27
fixture.js
Copy icon Copy

Use a new buildName name every time you run your test cases. This ensures that sessions are logically grouped under a unique build name and helps you monitor the health of your test suite effectively.

A build can only have a maximum of 1000 tests and post that a new build gets created with a ‘-1’ suffixed to the original build name.

Mark test as passed or failed

To mark whether your test has passed or failed on BrowserStack, use the Javascript executor in your test script. You can mark a test as passed or failed based on your test assertions.

The arguments passed in the Javascript method for setting the status and the corresponding reason of the test are status and reason

  • status accepts either passed or failed as the value
  • reason accepts a string value

Set up debugging capabilities

Use the following common debugging capabilities for your tests:

  1. Set the the debug capability to record video of the entire test execution
  2. Console Logs with log level ‘errors’ are enabled by default. Set the console capability to enable different log levels, such as warnings, info, verbose, errors, and disable.
