The Basics of Mobile Web Testing on Real Devices Using Appium / Selenium

Introduction

With mobile internet usage surpassing desktop usage and people spending most of their time on smartphones, mobile apps have become critical for businesses to engage and retain customers. However, with advanced mobile devices and operating systems releasing every year, testing mobile apps thoroughly across this device diversity poses а significant challenge. This is where Selenium mobile testing comes into the picture.

Selenium is the most popular open-source test automation framework used by development teams worldwide for web application testing. With mobile apps being web apps wrapped in а native shell, Selenium offers effective capabilities for automated testing of mobile apps as well. In this guide, we will understand Selenium’s offerings for mobile test automation and how they empower teams to deliver bug-free mobile app experiences across а multitude of devices.

The Need for Selenium Mobile Testing

As per Statista, people downloaded 230 billion mobile apps in 2021, and this number is poised to grow to 258 billion by 2025. However, with over 24,000 unique Android device configurations in the market, ensuring а seamless user experience across devices is easier said than done.

This extraordinary device fragmentation calls for rigorous mobile testing on real devices, simulators, and emulators. Executing elaborate test suites manually on such а vast array of devices is practically impossible. Selenium’s test automation capabilities bridge this gap by enabling test parallelization across hundreds of real mobile devices in the cloud.

Let us go through some unique Selenium offerings for automated mobile testing:

Selendroid for Android Testing

Selendroid is an open-source mobile test automation framework based on Selenium and specialized for testing native or hybrid Android applications. It leverages Selenium WebDriver to inspect and interact with the user interface elements of an Android app like buttons, text fields, and gestures programmatically.

Compared to other Android test automation tools, Selendroid stands out with features like:

Support for testing on emulators, simulators and real Android devices seamlessly

Selendroid supports testing Android apps on emulators, simulators, and real devices without any modifications to the tests. It handles Android gestures like taps, long presses, swipes etc., seamlessly across different environments. Unlike some tools that need changes when shifting between the emulator and real devices, Selendroid provides а consistent experience. This unified approach saves significant test maintenance efforts.

By supporting real devices out-of-the-box, Selendroid enables true-to-life testing on the same hardware and software that end users will have. Testing realistically on many different real Android devices is essential for ensuring the app works as expected for your diverse user base but doing so manually is time-consuming. 

With Selendroid, you can automate this critical testing efficiently. Its support for emulators/simulators in addition to real devices provides flexibility to test early in development before real devices are available while still allowing realistic testing later.

Overall, seamless testing across multiple Android environments accelerates test cycles, improves test coverage, and reduces maintenance costs for sustainable test automation with Selendroid.

Interaction with multiple Android activities and switching between them

Selendroid enables testers to easily interact with multiple activities of the Android app during test execution. The hierarchical activity structure of Android apps can make handling transitions tricky, but Selendroid simplifies interacting with and switching between activities.

Its API exposes Android activities and fragments to test code so you can programmatically launch activities, fill out forms, click buttons, and validate behavior across various screens. Selenium focuses mainly on one activity while Selendroid can gracefully handle multiple activities coming and going dynamically during testing.

By leveraging instrumentation instead of WebDriver, Selendroid has specialized support for understanding Android activities natively. You can start activities automatically as needed or manually control sequence and life cycles. Robust activity switching reduces flakiness by mitigating synchronization issues.

Overall, Selendroid delivers resilient automation for complex real-world Android apps with dynamic UIs across various activities.

Integration with the Android instrumentation framework for enhanced test reports

Selendroid integrates tightly with Android instrumentation to enable test metrics and reporting musicians not accessible in other UI automation tools. Beyond functionality testing, instrumentation provides insight into performance.

It gathers key stats like CPU utilization, memory consumption, network traffic, and battery drain along with typical test pass/fail rates. Such detailed telemetry is invaluable for detecting issues that impact user experience, like slow screens or excessive battery/data usage.

By surfacing Android instrumentation natively in Selendroid, test reports shine a light on areas to optimize. The team can assess the impacts of product changes on field metrics measured by instrumentation. With other tools, you only validate functionality rather than true user-centric quality.

These capabilities make Selendroid ideal for continuous and integration testing workflows. Teams can execute automated smoke, sanity, and regression test suites on the latest app builds pre and post-release across manifold Android OS versions and device configurations in parallel.

Appium for Cross-Platform App Testing

While Selendroid covers Android test automation, Appium caters to the need for testing iOS and cross-platform mobile apps. It is an open-source test framework built on the Selenium WebDriver model enhanced for native, hybrid and mobile web apps.

Here’s what makes Appium well-suited for test automation in the complex mobile landscape:

1. Single framework to test iOS, Android and Windows mobile apps using the same API

2. Supports an extensive range of programming languages like Java, Python, C#, Ruby etc. for writing test scripts

3. Active open source community with 1500+ contributors for framework enhancements

4. AI-based capabilities like visual testing, object recognition and more for intelligent test automation

These Appium capabilities augment mobile test coverage while minimizing effort. Teams can design automation suites with advanced validation mechanisms running across а globally distributed mobile device cloud. This accelerates go-to-market while also improving app quality.

Integrating Selenium with Real Device Cloud

While Selenium frameworks enable test creation and execution, running these tests at scale across an expansive test matrix covering devices, OS versions etc. is challenging. Relying solely on in-house test labs leads to constrained test coverage and delays.

This is where real device cloud solutions like LambdaTest come into the picture with features like:

1. Access to 5000+ unique real Android and iOS devices updated with the latest OS versions

2. Smart Test Distribution to run 100s of tests in parallel, achieving quicker test completion

3. Integrated online device labs for previewing and debugging tests without any setup

4. HyperExecute to cut test run times by minimizing test failures through smart test scheduling and 70% faster than traditional automation.

By integrating Selenium tests into the LambdaTest real device cloud, teams can shift mobile testing left in the development lifecycle. This amplifies test coverage across an ever-expanding mobile landscape while accelerating release velocity.
