Write Tests with Appium Vega Driver

​

Prerequisites

1. Complete the steps in Set Up Testing with Appium.
2. Review Manage Appium Sessions for capabilities configuration.
3. Confirm if the Appium server is running on default port 4723:
   curl http://localhost:4723/status
   
4. Have a Vega-supported Fire TV device or Vega Virtual Device with a target app installed.

​

Write your test script

1. Choose your preferred integrated development environment and programming language.
2. Create a new file with the following code snippet: Python:
   from appium import webdriver
   from appium.options.common import AppiumOptions
   
   bridge = "vda"
   desired_caps = {
       "platformName": "Kepler",
       "appium:automationName": "automation-toolkit/JSON-RPC",
       "browserName": "",
       "kepler:device": f"{bridge}://default"  # Or, replace 'default' with a Device Serial Number (DSN)
   }
   desired_caps = AppiumOptions().load_capabilities(desired_caps)
   
   appium_url = "http://127.0.0.1:4723"
   
   def appium_session():
       driver = webdriver.Remote(appium_url, options=desired_caps)
       try:
           output = driver.execute_script("shell", 'echo "Hello World!"')
           if "Hello" in output:
               print(f"Execute script command run was successful:\n{output}")
           else:
               print("Something went wrong")
           finally:
               driver.quit()
   
       if __name__ == '__main__':
           appium_session()
   
   JavaScript:
       const {remote} = require('webdriverio');
   
   const capabilities = {
       platformName: 'Kepler',
       'appium:automationName': 'automation-toolkit/JSON-RPC',
       'kepler:device': 'vda://default',
       'appium:appURL': 'com.amazon.keplervideoapp.main',
   };
   
   const opts = {
       hostname: 'localhost',
       port: 4723,
       logLevel: 'info',
       capabilities,
   };
   
   const test = async function runTest() {
       const driver = await remote(opts);
       try {
           const element = await driver.$('//children[@test_id="card169309"');
   
           // getElementRect command
           const rect = await driver.getElementRect(element.elementId);
   
           console.log(`x: ${rect.x}, y: ${rect.y}, width: ${rect.width}, height: ${rect.height}`);
       } finally {
           await driver.deleteSession();
       }
   }
   
   test().catch(console.error);
   
   Java: Java requires compilation and dependency management. Use Maven or Gradle to handle these requirements automatically. Project setup using Maven
   1. Check for Maven installation.
   mvn --version
   
   2. Create a pom.xml in your project root.
   <project>
   <modelVersion>4.0.0</modelVersion>
   
   <groupId>com.amazon.akd</groupId>
   <artifactId>kepler-test</artifactId>
   <version>1.0-SNAPSHOT</version>
   
   <dependencies>
           <dependency>
           <groupId>io.appium</groupId>
           <artifactId>java-client</artifactId>
           <version>8.5.1</version>
           </dependency>
   </dependencies>
   </project>
   
   3. Create a test class. See text class.
   Project setup using Gradle
   1. Verify Gradle installation:
   gradle --version
   
   2. Create build.gradle in your project root:
   plugins {
       id 'java'
       id 'application'
   }
   
   repositories {
       mavenCentral()
   }
   
   dependencies {
       implementation 'io.appium:java-client:8.5.1'
   }
   
   application {
       mainClass = 'com.amazon.akd.commands.page_and_source.ExecuteScriptExample'
   }
   
   3. Create settings.gradle.
   rootProject.name = 'kepler-test'
   
   4. Create a test class. See text class.

​

Test class

package com.amazon.akd.commands.page_and_source;

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.remote.options.BaseOptions;

import java.net.MalformedURLException;
import java.net.URL;

public class ExecuteScriptExample {
    public static void main(String[] args) throws MalformedURLException {
        BaseOptions options = new BaseOptions()
                .setPlatformName("Kepler")
                .setAutomationName("automation-toolkit/JSON-RPC")
                .amend("kepler:device", "vda://default")
                .amend("appium:appURL", "com.amazon.keplervideoapp.main");

        AppiumDriver driver = new AppiumDriver(
                new URL("http://127.0.0.1:4723"), options
        );

        try {
            // execute_script command
            String output = driver.executeScript("shell", "echo 'Hello World!'").toString();
            System.out.println(output);
        } finally {
            driver.quit();
        }
    }
}
