Migrating to Device Farm desktop browser testing from local Selenium WebDrivers

To migrate

This procedure shows you how to configure your local WebDriver tests to use Selenium's RemoteWebDriver with a URL from the GetTestGridUrl API call.

To perform these steps, you need an AWS account and a working set of tests.

1. To keep track of your sessions, you must create a project.

   Console

   1. Sign in to the Device Farm console at https://console.aws.amazon.com/devicefarm.

   2. In the navigation pane, choose Desktop Browser Testing, and then choose Projects.

   3. If you already have a project, under Desktop browser testing projects, choose the name of your project.

      Otherwise, to create a new project, choose New project. Then, on the Create Project page, do the following:

      1. Enter a Project name.

      2. (Optional) Enter a project Description.

      3. (Optional) Under Virtual Private Cloud (VPC) Settings, you can configure your project's VPC peering settings by choosing the VPC, its Subnets, and its Security Groups. For instructions on connecting Device Farm to a VPC, see Working with Amazon Virtual Private Cloud across Regions in the Device Farm Developer Guide.

      4. Choose Create.

   4. In the project details, note the project's Amazon Resource Name (ARN). It looks like this: arn:aws:devicefarm:us-west-2:111122223333:testgrid-project:123e4567-e89b-12d3-a456-426655440000.

      Note

      For instructions on updating your project configuration, see Configuring your project to use Amazon VPC endpoints.

   AWS CLI

   Use the create-test-grid-project command to create a project:

   aws devicefarm create-test-grid-project --name "Peculiar Things"

   Make a note of the project ARN, which is used by your application:

   {
       "testGridProject": {
           "arn": "arn:aws:devicefarm:us-west-2:111122223333:testgrid-project:123e4567-e89b-12d3-a456-426655440000",
           "name": "Peculiar Things"
       }
   }

   Note

   To update your project configuration, see Configuring your project to use Amazon VPC endpoints.

2. To use the desktop browser testing feature, you must install and configure the AWS SDK for the language appropriate for your tests.

3. Modify your environment to include your AWS access and secret keys. The steps vary depending on your configuration, but involve setting two environment variables:

   Important

   We recommend that you follow the standard security advice of granting least privilege—that is, granting only the permissions required to perform a task—when you configure the AWS SDK and AWS CLI with credentials. For more information, see AWS Security Credentials and IAM Best Practices.

   AWS_ACCESS_KEY_ID=AKIAIOSFODNN7EXAMPLE
   AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY

4. Instead of creating a WebDriver for your browser (for example, GeckoDriver) create a RemoteWebDriver and get a URL from the desktop browser testing feature.

   Java

   Note

   This example uses JUnit 5 and the AWS SDK for Java 2.x. For more information about the AWS SDK for Java 2.x, see AWS SDK for Java 2.x API Reference. If you are using a different test framework, be aware that @Before and @After are called before and after each test, respectively.

   // Import the AWS SDK for Java 2.x Device Farm client:
   import software.amazon.awssdk.regions.Region;
   import software.amazon.awssdk.services.devicefarm.*;
   import software.amazon.awssdk.services.devicefarm.model.*;
   import java.net.URL;
   
   // in your tests ...
   public class MyTests {
     // ... When you set up your test suite
     private static RemoteWebDriver driver;
   
     @Before
     void setUp() {
       String myProjectARN = "arn:aws:devicefarm:us-west-2:111122223333:testgrid-project:123e4567-e89b-12d3-a456-426655440000";
       DeviceFarmClient client  = DeviceFarmClient.builder().region(Region.US_WEST_2).build();
       CreateTestGridUrlRequest request = CreateTestGridUrlRequest.builder()
         .expiresInSeconds(300)
         .projectArn(myProjectARN)
         .build();
       CreateTestGridUrlResponse response = client.createTestGridUrl(request);
       URL testGridUrl = new URL(response.url());
       // You can now pass this URL into RemoteWebDriver.
       WebDriver driver = new RemoteWebDriver(testGridUrl, DesiredCapabilities.firefox());
     }
     
     @After
     void tearDown() {
       // make sure to close your WebDriver:
       driver.quit();
     }
   
   }

   Python

   Important

   This example is written with the assumption you are using Python 3 with pytest. If you are using another testing framework, see the documentation.

   
   # Include boto3, the Python SDK's main package:
   import boto3, pytest
   
   # in your tests:
   # Set up the Device Farm client, get a driver URL:
   class myTestSuite:
     def setup_method(self, method):
       devicefarm_client = boto3.client("devicefarm", region_name="us-west-2")
       testgrid_url_response = devicefarm_client.create_test_grid_url(
         projectArn="arn:aws:devicefarm:us-west-2:111122223333:testgrid-project:123e4567-e89b-12d3-a456-426655440000",
         expiresInSeconds=300)
       self. driver = selenium.webdriver.Remote(testgrid_url_response["url"], selenium.webdriver.DesiredCapabilities.FIREFOX)
   
     # later, make sure to end your WebDriver session:
     def teardown_method(self, method):
       self.driver.quit()

5. Run your tests as you would normally.
