Getting Started with Appium 2.0

Step 1: Setting Up the Environment

The first step in starting with Appium 2.0 is setting up your testing environment. This involves installing Node.js, as Appium 2.0 is a Node.js application.

1. Install Node.js: You can download the installer from the official Node.js website. Follow the installation instructions.

Install Appium 2.0: Once Node.js is installed, you can install Appium 2.0 using npm (Node Package Manager). Run this command:

npm install -g appium

2. This will install the latest version of Appium globally on your system.

Verify Installation: After installation, verify that Appium 2.0 is installed correctly by running:

appium -v

3. This command should return the version number of Appium, confirming that the installation was successful.

Step 2: Understanding Drivers and Plugins in Appium 2.0

A key feature of Appium 2.0 is its modular architecture, which separates the core Appium framework from drivers and plugins. This allows users to install only the components they need.

Drivers: Drivers are the components that interface with different platforms. With Appium 2.0, you can install or uninstall drivers as needed. For instance, if you're only testing Android, you can install only the Android driver.

appium driver install uiautomator2

‍Plugins: Plugins are additional modules that extend Appium's functionality. They can be used for specific purposes like logging, performance analysis, or custom commands.

appium plugin install --source=npm appium-wait-plugin

Step 3: Writing Your First Test Script

const wdio = require("webdriverio");

const opts = {
    path: '/wd/hub',
    port: 4723,
    capabilities: {
        platformName: "Android",
        platformVersion: "10.0",
        deviceName: "Android Emulator",
        app: "/path/to/your/app.apk",
        automationName: "UiAutomator2"
    }
};

async function main() {
    const client = await wdio.remote(opts);

    const el = await client.$("~Button");
    await el.click();

    await client.deleteSession();
}

main();

This script initializes an Appium session, finds a button element in an Android application, clicks it, and ends the session. The key points in this script include specifying the platform (Android, in this case) and defining the path to your application.

Step 4: Running Your Tests

Once you have written your test script, running it is straightforward. You can execute the script directly from your terminal or command prompt:

node your-test-script.js

Appium 2.0 will start the session, execute the commands, and provide feedback through the console output if everything is set up correctly.

Step 5: Analyzing Results and Debugging

Getting started with Appium 2.0 also involves learning how to analyze test results and debug issues. Appium provides detailed logs to help you understand what happened during the test execution. If a test fails, these logs are your first resource for diagnosing the problem.
