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

  • Automatic (Browserstack SDK)
    Plug-n-play solution that takes care of all the integration steps for you
  • Manual (Language bindings)
    Start and stop the BrowserStack Local tunnel within your test suite manually

Using the BrowserStack SDK is the recommended integration method for Python. The SDK auto-handles your integration steps.


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.

# Set these values in your ~/.zprofile (zsh) or ~/.profile (bash)
export BROWSERSTACK_USERNAME="YOUR_USERNAME"
export 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

Use BrowserStack credentials in your test cases

Update your test cases to read BrowserStack credentials from environment variables and point the Selenium hub to the BrowserStack remote hub URL.

test-script.py

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.

  • PIP - Language Bindings
  • CLI Interface - Binary

Install the package

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

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:

test-script.py

Add capabilities to enable BrowserStack local

test-script.py

Set the local capability to true.

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.

test-script.py

Set the browserstack.local capability to true.

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.

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

# 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.

Set up config to enable local

Set the local capability to true.

test-script.py

Set the browserstack.local capability to true.

test-script.py

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

test-script.py

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

test-script.py

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

Capability Description
sessionName Name for your test case. For example, Homepage - Get started
buildName CI/CD job or build name. For example, Website build #23, staging_1.3.27
projectName Name of your project. For example, Marketing Website

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

test-script.py

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

test-script.py

Use the following common debugging capabilities for your tests:

  1. Set the the debug capability to enable visual logs and capture screenshots at every Selenium command automatically.
  2. Console Logs with log level ‘errors’ are enabled by default. Set the consoleLogs capability to enable different log levels, such as warnings, info, verbose, errors, and disable.
  3. Set the networkLogs capability to capture the browser’s performance data such as network traffic, latency, HTTP requests, and responses in a HAR format.

Commonly used features and advanced-use cases

Here’s a list of features and capabilities you may find useful.
