Run accessibility checks on an Espresso sample repo

Get the sample app and test suite

• Download BrowserStack’s sample Calculator app and Calculator test suite.

Upload the app

Upload the sample app (.apk or .aab file) to the BrowserStack servers using a REST API request.

The following sample cURL command demonstrates how to upload an app:

curl -u "YOUR_USERNAME:YOUR_ACCESS_KEY" \
-X POST "https://api-cloud.browserstack.com/app-automate/espresso/v2/app" \
-F "file=@/path/to/app/file/App.apk"

A sample response for the request is shown below:

{
    "app_name":"Application-debug.apk",
    "app_url":"bs://j3c874f852ea50957a3fdc33f47514288c4ba4",
    "app_version":"1.0",
    "app_id":"j3c874f852ea50957a3fdc33f47514288c4ba4",
    "uploaded_at":"2022-05-12 07:27:54 UTC",
    "expiry":"2022-06-11 07:27:54 UTC"
}

Use the app_id parameter to identify the application when you run Espresso tests.

Upload the test suite

Upload the sample test suite (.apk file) to the BrowserStack servers using a REST API request.

The following sample cURL command demonstrates how to upload a test suite:

curl -u "YOUR_USERNAME:YOUR_ACCESS_KEY" \
-X POST "https://api-cloud.browserstack.com/app-automate/espresso/v2/test-suite" \
-F "file=@/path/to/app/file/Application-debug-test.apk"

A sample response for the request is shown below:

{
    "test_suite_name":"Application-debug-test.apk",
    "test_suite_url":"bs://f7c874f21852ba57957a3e31f47514288c4ba4",
    "test_suite_id":"f7c874f21852ba57957a3e31f47514288c4ba4",
    "uploaded_at":"2022-05-12 07:32:41 UTC",
    "expiry":"2022-06-11 07:32:41 UTC",
    "framework":"espresso"
}

Use the test_suite_id parameter to identify the test suite when you run Espresso tests.

Run Espresso tests

In a cURL command, include the following parameters and send the API request to run the test.

• app: specify the app_id, which is the unique identifier of the application that you want to test. The app_id is generated when you upload the app to BrowserStack, see Upload your app.
• testSuite: specify the test_suite_id, which is the unique identifier of the test suite you want to run. The test_suite_id is generated when you upload your test suite to BrowserStack, see Upload your test suite.
• devices: specify a list of Android devices on which you want to test your app. For more information, see Specify devices.
• accessibility: enable accessibility checks.

curl -u "USERNAME:ACCESS_KEY" \
-X POST "https://api-cloud.browserstack.com/app-automate/espresso/v2/build" \
-d "{
    \"app\": \"bs://$app_id\",
    \"testSuite\": \"bs://$test_suite_id\",
    \"devices\": ["Samsung Galaxy S24-14.0"]
    \"deviceLogs\": true,
    \"project\": \"$PROJECT_NAME\",
    \"accessibility\": true,
    }
}" \
-H "Content-Type: application/json"

Response

A sample response for the request is shown below:

{
    "message" : "Success",
    "build_id" : "4d2b4deb810af077dd98f479bfdd2e64f36c3"
}

The build_id uniquely identifies your build in App Automate. Each test build is an execution of the Espresso test suite on all selected devices.

If your tests fail with a NO TESTS RAN error, refer to the No tests ran guide.

View test results

After you run the test using the REST API, visit the App Automate dashboard to view your test results, debug logs, and overall test details.

Visit App Accessibility dashboard

You can also use API requests to view the test results.
