Examples

Setup

This page contains complete NodeJS example scripts for running Appium tests on different devices available on the TV Labs platform.

To run these examples, first setup your environment:

mkdir tvlabs-appium-examples && cd tvlabs-appium-examples
npm init -y
npm install --save webdriverio

echo "TVLABS_API_KEY=<tvlabs_api_key>" >> .env
echo "TVLABS_BUILD_ID=$(tvlabs upload -i <path to your application package here>)" >> .env

touch index.js

To run the script after you populate index.js with one of the below examples, run node --env-file=.env index.js.

Smartcast (Vizio)

note

The SmartCast driver is closed source. You can find a reference of available commands and key mappings in the appium-smartcast-driver documentation.

import { remote } from 'webdriverio';

const capabilities = {
  'tvlabs:constraints': {
    platform_key: 'smartcast',
  },
  'tvlabs:build': process.env.TVLABS_BUILD_ID,
};

const wdOpts = {
  hostname: process.env.APPIUM_HOST || 'appium.tvlabs.ai',
  port: parseInt(process.env.APPIUM_PORT, 10) || 4723,
  protocol: 'https',
  logLevel: 'info',
  capabilities,
  headers: {
    Authorization: `Bearer ${process.env.TVLABS_API_KEY}`,
  },
  connectionRetryTimeout: 60_000,
};

async function runTest() {
  const driver = await remote(wdOpts);

  try {
    await driver.executeScript('smartcast: pressKey', [{ key: 'right' }]);

    await driver.pause(1000);

    await driver.executeScript('smartcast: pressKey', [{ key: 'left' }]);

    await driver.pause(1000);

    await driver.$('#my-element').getText();
  } finally {
    await driver.pause(1000);
    await driver.deleteSession();
  }
}

Using @tvlabs/wdio-service

Beginning with any of the examples above (Roku for this example), run the following command to install the WebdriverIO service:

npm install --save @tvlabs/wdio-service

Then modify the script to use the service:

import { remote } from 'webdriverio';
import TVLabsService from '@tvlabs/wdio-service';
import fs from 'fs';

const capabilities = {
  'tvlabs:build': process.env.TVLABS_BUILD_ID,
  'tvlabs:constraints': {
    platform_key: 'roku',
  },
};

const wdOpts = {
  hostname: process.env.APPIUM_HOST || 'appium.tvlabs.ai',
  port: parseInt(process.env.APPIUM_PORT, 10) || 4723,
  protocol: 'https',
  logLevel: 'info',
  capabilities,
  headers: {
    Authorization: `Bearer ${process.env.TVLABS_API_KEY}`,
  },
  connectionRetryTimeout: 60_000,
};

const serviceOpts = {
  apiKey: process.env.TVLABS_API_KEY,
};

async function runTest() {
  // Unused here, but usually provided by the WebdriverIO test runner.
  const wdioOptions = {};
  const specs = [];
  const cid = '';

  const service = new TVLabsService(serviceOpts, capabilities, wdioOptions);

  // This modifies capabilities, adding the TV Labs session ID.
  await service.beforeSession(wdOpts, capabilities, [], '');

  // Proceed normally!
  const driver = await remote(wdOpts);

  try {
    await driver.executeScript('roku: deviceInfo', []);

    await driver.executeScript('roku: pressKey', [{ key: 'Right' }]);

    await driver.pause(1000);

    await driver.executeScript('roku: pressKey', [{ key: 'Left' }]);

    const screenshot = await driver.takeScreenshot();

    fs.writeFileSync('./screenshot.png', screenshot, { encoding: 'base64' });
  } finally {
    await driver.pause(1000);
    await driver.deleteSession();
  }
}

runTest();
