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.

BrowserStack Reporting

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

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 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 2: Set the buildIdentifier as the build number or time of the required build as seen on the dashboard:

buildName: bstack-demo
buildIdentifier: 123

Use additional 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:

Create browserstack.yml file

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

Copy snippet

[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.

Copy snippet

<path> - Mention the absolute path to the directory where you want to save dotnet x64
<version> - Mention the dotnet version which you want to use to run tests

This command performs the following functions:

Installs dotnet x64
Installs the required version of dotnet x64 at an appropriate path
Sets alias
Sets an alias for the dotnet installation location on confirmation (enter y option)
The command sets the installation path in your ~/.zshrc (zsh) or ~/.bashrc (bash) profile and you can use this alias to run your tests later. If you choose not to set the alias, when you run the tests, you have to use the entire path to the installation location on every test run.

Update 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.

Troubleshooting

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

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.
