Integrate your test suite with BrowserStack
BrowserStack’s NUnit SDK supports a plug-and-play integration. Run your entire test suite in parallel in a few steps!
Prerequisites
- An existing automated test suite.
- .Net v5.0+ and NUnit v3.0.0+.
If you are using Mac computers with Apple silicon chips, use the BrowserStack SDK CLI workflow.
Integration steps
If you want to get started with our starter project, refer to our NUnit sample project. If you are using our sample project, you do not need to follow the integration steps.
Based on the method you use to build your project, follow these steps to integrate your test suite with BrowserStack.
Set BrowserStack credentials
Save your BrowserStack credentials as environment variables. It simplifies running your test suite from your local or CI environment.
Add BrowserStack SDK as NuGet package
Steps to install BrowserStack SDK as a NuGet package:
- On the Visual Studio toolbar, select Project → Manage NuGet Packages. A NuGet Package Manager Window opens.
- In the Browse tab, search for BrowserStack.TestAdapter, and click Install.
Create your BrowserStack config file
After installing 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 access credentials
Set userName and accessKey parameters in the browserstack.yml file, available in the root directory, to authenticate your 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.
Do you want to dynamically configure platforms?
To dynamically configure platforms across different tests, you can comment out the platforms capability while still passing platform-specific capabilities.
Set number of parallel 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 (3 x 2) 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.
Do you want to perform cross-browser testing without test level parallelization?
Remove the parallelsPerPlatform capability from the configuration file.
Do you want to test parallelization without performing cross-browser testing?
Remove or comment out the platform capability while keeping the parallelsPerPlatform capability intact in the configuration file.
Do you want to skip cross-browser testing as well as parallelization?
Remove or comment out the platform and parallelsPerPlatform capabilities from the configuration file.
Enable BrowserStack Local
Test localhost/internal servers in your network
BrowserStack’s Local Testing feature connects with test suites pointing to your localhost URL
BrowserStack Local supports all advanced use cases and restricted networks. Contact our support team for assistance in configuring BrowserStack Local for your enterprise.
BrowserStack Reporting
You can leverage BrowserStack’s extensive reporting features using the following capabilities:
Set a name to your build (usually the same as the build ID that’s on your CI/CD platform).
Accepted characters: A-Z, a-z, 0-9, ., :, -, [], /, @, &, ', _. All other characters are ignored.
Character limit: 255
| buildIdentifier | Description | Generated build name on 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” dotnet test --filter "Category=sample-test"
Windows Powershell:
$env:BROWSERSTACK_BUILD_NAME=“bstack-demo 123”; dotnet test --filter "Category=sample-test"
Windows cmd:
set BROWSERSTACK_BUILD_NAME="bstack-demo 123" && dotnet test --filter "Category=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.
Do you want to enable/disable auto-marking of test status and session?
The sessionName and sessionStatus are the names of your test sessions and status of your test sessions respectively. They are automatically picked from your test class/spec names and statuses. They do not need to be set manually when using the BrowserStack SDK. To override the sessionName and sessionStatus capabilities, use the following in your browserstack.yml file:
You can configure local testing to start without initializing the BrowserStack binary, or even with an existing binary using a local identifier
testContextOptions:
skipSessionName: true
skipSessionStatus: true
Use additional debugging features
BrowserStack offers session logs, screenshots of failed commands, and a video of the entire test, with additional options to enable.
Use Percy Visual Testing
Percy is an all-in-one visual testing and review platform enabling teams to automate visual tests, detect visual bugs, and provide valuable insights into UI changes.
percyCaptureMode takes effect only if you set percy to true. If you set the capture mode to manual, ensure you use the Percy Screenshot function in your test script.
Update browserstack.yml file
Update the browserstack.yml file in the root folder of your test suite and add the following code to it.
Use our Capability Generator to select from a comprehensive set of options you can use to customize your tests.
Run your test suite
The BrowserStack Test Adapter enables you to execute your test suite seamlessly, just as you did previously.
- On the Visual Studio toolbar, select Test → Test Explorer.
- Right-click on your test and click Run.
Set BrowserStack credentials
Save your BrowserStack credentials as environment variables. It simplifies running your test suite from your local or CI environment.

[Only for Macs with Apple silicon] Install dotnet x64 on MacOS
If you are using a Mac computer with Apple silicon chip (M1 or M2) architecture, use the given command.

Update browserstack.yml file with selected capabilities
Copy the code snippet and replace the contents of the browserstack.yml file in the root folder of your test suite.
Use our Capability Generator to select from a comprehensive set of options you can use to customize your tests.
Run your test suite
Continue running your tests as you have been running previously. The command to run your tests using the BrowserStack SDK remains unchanged. For your reference, here’s a sample command:
Did not set the alias?
Use the absolute path to the dotnet installation to run your tests on Mac computers with Apple silicon chips as shown below:
</absolute/path/to/location/of/dotnet/>/dotnet test
To find out the location of the BrowserStack SDK log files, refer to BrowserStack SDK Log Files. If you are looking for more information, see FAQ documentation.
