Integrate Your C# Test Suite with BrowserStack

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

Ready to integrate your existing C# Appium test suite with BrowserStack? This document walks you through the simple steps to connect your tests to our cloud infrastructure and start running them on real devices. You’ll learn how to configure your environment, upload your app, and execute tests seamlessly on BrowserStack’s device cloud and achieve faster, more reliable mobile test execution.

Looking for a starter project? Get started with our C# sample project.

Prerequisites

An existing automated test suite.
.Net v6.0+ and NUnit v3.0.0+.

Integration steps

Based on the method you use to build your project, complete the steps in the following tabs to integrate with BrowserStack.

Visual Studio
CLI

Set BrowserStack credentials

Save your BrowserStack credentials as environment variables. It simplifies running your test suite from your local or CI environment.

Copy

Upload app

Upload your Android (.apk or .aab) or iOS (.ipa) apps to BrowserStack servers using one of the following ways:

Upload app using the App Automate dashboard

On the App Automate dashboard, click the Upload button on the top-right corner. Select the app you want to upload from your filesystem.

Upload app using App Management UI

To upload an app using the App Management UI, follow the steps below:

Navigate to App Automate dashboard, on the sidebar, click App Management.
On the App Management UI, click Upload App.
Select the app you want to upload from your filesystem. If you are uploading the app using a public URL, paste the URL of your app in the or upload from URL box.
After selecting the app, choose the App Automate framework you want to use for testing. You can optionally add flags and a custom ID.
Click Upload. The app is uploaded to the BrowserStack servers. You’ll receive an App ID, which you can use to run tests.

Upload apps from the filesystem using App Management UI

To manage your apps, refer to the documentation on managing apps using App Management UI.

Upload app using REST API

To upload an app using filesystem/public URL via the REST API, use the cURL example:

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 app to be tested

The app property determines the app to be tested. You can upload an Android app (.apk or .aab file) or an iOS app (.ipa file) from your local filesystem.

Supported method	Description
path(Recommended)	SDK uploads the app using the specified relative or absolute path. Eg: `app: ./SampleApp.apk`.

Check out how to create IPA files for iOS app testing on BrowserStack.

Other acceptable app property values

You can use BrowserStack REST API to upload your app.

Following is a sample response that is generated when you upload an app using any of the mentioned methods:

 {
    "app_url":"bs://f7c874f21852ba57957a3fdc33f47514288c4ba4", 
    "custom_id":"SampleApp",
    "shareable_id":"exampleuser/SampleApp"
 }

The following table explains the other acceptable app property values:

Supported method	Description
app_url	Uploaded app’s `app_url` is a valid value for `app` property. Eg: `app: bs://45e1c1473b17b7643aed1761f51cb5cdf3d3e334`
custom_id	If you’ve defined a `custom_id` while uploading your app, the same value can be used as `app` property value. Eg: `app: CalculatorApp`
shareable_id	If you wish to test an app uploaded by someone else from your organization, a `shareable_id` can be used as the `app` property value. Eg: `app: exampleuser/CalculatorApp`

Check out how to specify the application under test to understand the above options better.

Set platforms to test on

Set the devices you want to test under the platforms object.

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.

BrowserStack Reporting

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

The projectName and buildName config must be static and not change across different runs of the same build. This is a deviation in approach as specified by BrowserStack Automate or App Automate as Test Reporting & Analytics will automatically identify different build runs.

Restrict the characters in your projectName and buildName to alphanumeric characters (A-Z, a-z, 0-9), underscores (_), colons (:), square brackets ([, ]), and hyphens (-). Any other character will be replaced with an underscore (_).

Enable Local Testing and debugging features

To enhance your testing experience on BrowserStack, you can enable additional features such as Local Testing and debugging features by adding the respective capabilities in your browserstack.yml file.

Enable BrowserStack Local

To enable testing of apps hosted on your local machine or behind a firewall, you can use BrowserStack Local Testing. This feature creates a secure tunnel between your local machine and the BrowserStack cloud, allowing you to test your apps in real-time. For more information, refer to the Local Testing documentation.

browserstackLocal: true

Enable debugging features

By default, BrowserStack provides prettified session logs, screenshots on every failed command, and a video of the entire test. Additionally, you can enable the following features by setting the respective capabilities in your browserstack.yml file:

Create browserstack.yml file

Create browserstack.yml file in the root folder of your test suite and add the code to it.

Copy

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.

Troubleshooting

Here’s a list of troubleshooting options you may find useful.

Errors faced during app upload

When you upload your app to BrowserStack, make sure that the app file and its path or URL are valid. If you see an error during app upload, first check the following:

The file path is correct and the app file exists on your machine.
The app URL is publicly accessible and not behind a firewall or authentication.
The app file type is supported by BrowserStack. You can upload your app from the App Automate dashboard, App Management UI, or by using the REST API. For detailed information on uploading and managing apps, refer to Uploading and managing apps.

Invalid device OS combination errors

If you face errors related to invalid device OS combinations, ensure that the device and OS version combinations you are trying to run your tests on are supported on BrowserStack:

For detailed information on selecting devices, refer to the Select devices documentation.
To use regular expressions to specify device attributes, refer to the Using regex to select devices documentation.
To check the list of supported OS versions for devices on BrowserStack, refer to the App Automate supported devices documentation.

Resigned Apps and Third-Party Library Integration Issues

Uploading an unsigned version of an Android app will require us to sign it with our certificates before installing it on our devices. In the same manner, any uploaded .aab files will be converted into a universal APK and signed with our certificates.
If BrowserStack resigns the apps, third-party library integrations such as Google Firebase services, Google Maps SDK, Facebook SDK, etc., may not function properly if the use of API keys is restricted based on the SHA-1 certificate fingerprint of the app’s signing key.
To prevent this issue, it’s recommended to sign the APK with your own certificates before uploading it to BrowserStack.

Disabling Re-Signing for iOS Apps

If you upload an iOS app, we will re-sign the app with our own provisioning profile to be able to install your app on our devices during test execution.
However, if your app is signed using the Apple Developer Enterprise Program, you can disable this behavior to test features such as push notifications on BrowserStack devices.

Capability	Expected values
`resignApp`	A boolean. To disable re-signing, set the capability to `false` in your Appium test scripts.
