Integrate Your Test Suite with BrowserStack

BrowserStack Python SDK supports a plug-and-play integration. Run your entire test suite in parallel with a few steps!


  • An existing automated test suite.
  • Python3 and Pip3 is installed on your machine.

Integration Steps

Complete the following steps to integrate your Python test suite using BrowserStack SDK.

Set BrowserStack credentials

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

Install BrowserStack Python SDK

Execute the following commands to install BrowserStack Python SDK for plug-and-play integration of your test suite with BrowserStack.

python3 -m pip install browserstack-sdk
browserstack-sdk setup --username "YOUR_USERNAME" --key "YOUR_ACCESS_KEY"
python3 -m pip install browserstack-sdk
browserstack-sdk setup --username "YOUR_USERNAME" --key "YOUR_ACCESS_KEY"
Unable to install BrowserStack SDK?

If you can’t install BrowserStack SDK due to sudo privilege issues, create a virtual environment and execute the adjacent installation commands again.

Mac OS or Linux:
python3 -m venv env
source env/bin/activate

python3 -m venv env

Create your BrowserStack config file

Once you have installed the SDK, create a browserstack.yml config file at the root level of your project. This file holds all the required capabilities to run tests on BrowserStack.

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

Enable BrowserStack Local

Test localhost/internal servers in your network

Test Localhost/Staging websites that are not publicly accessible

BrowserStack Local Testing feature connects with test suites that test your localhost URL

BrowserStack Reporting (part 1/2)

You can leverage BrowserStack’s extensive reporting features using the following capabilities:

Build Name

Set build name as the name of the job/test suite being run. Accepted characters: A-Z, a-z, 0-9, ., :, -, [], /, @, &, , _. All other characters are ignored.
Character limit: 255

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 Names

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:


BROWSERSTACK_BUILD_NAME=“bstack-demo 123” browserstack-sdk python ./tests/

Windows Powershell:

$env:BROWSERSTACK_BUILD_NAME=“bstack-demo 123”; browserstack-sdk python ./tests/

Windows cmd:

set BROWSERSTACK_BUILD_NAME=“bstack-demo 123” && browserstack-sdk python ./tests/

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

Project Name

Set a project name for your project

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

Network logs

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


Create browserstack.yml file

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

BrowserStack Reporting (part 2/2)

Test assertions are specific to selected language frameworks. BrowserStack requires explicit instruction to determine whether your tests have passed or failed based on the assertions in your test script.

Mark session name

You can use the sessionName capability to give your session a name (usually describing the test case) so that it is easy for you to debug later.

Mark test as passed or failed

To mark whether your test has passed or failed on BrowserStack, use the following Javascript executor in your test script.

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 value in string datatype
Copy icon Copy snippet

Run your test suite

Prepend browserstack-sdk before your existing run commands to execute your tests on BrowserStack using the Python SDK.

python <path-to-test-files>

browserstack-sdk python <path-to-test-files>

After you run your test, visit the Automate dashboard to view your test results.

Advanced features and use cases

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

Accept insecure certificates

The acceptInsecureCerts capability suppresses browser popups warning about self-signed certificates usually found in staging environments.

Capability Expected values
