What Is Appium?
Appium is an open-source mobile test automation framework that enables testing of Android, iOS, and hybrid mobile applications using a single API.
Its main goal is simple: automate real user interactions to ensure mobile application quality.
Why Appium?
Appium provides several advantages:
- Cross-platform support (Android and iOS)
- Supports Native, Hybrid, and Mobile Web apps
- Multiple programming languages:
- Java
- JavaScript
- Python
- Ruby
- C#
This flexibility allows teams to use their existing tech stack without learning a new language.
How Appium Works
Appium follows the WebDriver protocol.
Flow:
Test Code -> Appium Server -> Native Drivers -> Mobile Device
Under the hood:
- Android -> UiAutomator2
- iOS -> XCUITest
This architecture enables: "Write once, run on multiple devices."
You can reuse most of your test logic across platforms.
