Integrate Your Test Suite with BrowserStack

BrowserStack supports out of the box integration with WebdriverIO. All you need is a few changes in your existing WebdriverIO config file and you’re good to go!

Prerequisites

  • Node.js 8.11.2+ installed on your system.
  • An existing WebdriverIO based automation test suite.

Integration Steps

Set BrowserStack credentials

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

Install BrowserStack WDIO service

Use either of the following ways to install BrowserStack WDIO service to your project:

npm install @wdio/browserstack-service --save-dev
"devDependencies": {
  "@wdio/browserstack-service": "^7",
}

Update your WebdriverIO config file

Update your configuration file with the following parameters to run tests on BrowserStack.
At the end of this step, you will have a sample configuration file with BrowserStack capabilities to use in your project.

Add BrowserStack service

Add browserstack to the services list in your configuration file. if you’re using our sample repo, the test.conf.js configuration file in your preferred project folder(android/iOS) has to be changed.

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

Set the path to your app. Or, if you have already uploaded your app, provide one of the other acceptable app property values here

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.

Select Android or iOS devices from a list of 150+ available combinations

Use one of our sample apps to run your first Appium test on BrowserStack App Automate. Choose from the options below:

Parallel thread #1
Parallel thread #2
Parallel thread #3

Configure maxInstances to set the number of parallels

You can create multiple threads for parallel execution by adding maxInstances capability. The maxInstances number represents the maximum number of devices that should be created in parallel in BrowserStack.
Example: maxInstances: 4

Enable BrowserStack Local

Test apps with local/staging API servers

True
False
Test apps locally with local/staging API servers

BrowserStack’s Local Testing feature connects with locally hosted API servers to run your apps

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 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 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 : in your test.conf.js file.

exports.config = {
  //..
  services: [
      ['browserstack', {
          buildIdentifier: '#${BUILD_NUMBER}',
          // ..
      }]
  ],
  //...
  commonCapabilities: {
    'bstack:options': {
      buildName: 'bstack-demo',
    }
  }
};

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 in your test.conf.js file. (We shouldn’t set any value for buildIdentifier to achieve it) :

commonCapabilities: {
  'bstack:options': {
    buildName: 'bstack-demo 123',
  }
}

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

exports.config = {
  //..
  services: [
      ['browserstack', {
          buildIdentifier: '123',
          // ..
      }]
  ],
  //...
  commonCapabilities: {
    'bstack:options': {
      buildName: 'bstack-demo',
    }
  }
};


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:

Test Observability

Enables Test Observability, an advanced test reporting and debugging tool that helps you analyze test failures dramatically faster. If enabled, Test Observability collects test data using the SDK. This capability is enabled (set to true) by default.

True
False
Visual logs

Enables screenshots for every selenium command ran

True
False
Network logs

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

True
False

Use App Percy Visual Testing

App 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.

Percy Visual Testing

Enable visual testing to automatically identify and highlight visual UI changes.

Note: Using App Percy to perform Visual testing affects the performance of your App Automate tests.

True
False
Note: 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 configuration file with selected capabilities

Copy the following code snippet and add it to your configuration file of your test suite.

test.conf.js
Copy icon Copy snippet

You can also pass regular expressions (regex) in deviceName and platformVersion capabilities if your device selection is more flexible. Check out how to use regular expressions to specify device attributes.

Run your test suite

Your test suite is now ready to run on BrowserStack. Use the commands defined in your package.json file to run the tests.

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

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 browserstack.resignApp capability to false in your Appium test scripts.
test.conf.js
