Appium Best Practices Every Developer Must Know

I used to think most Appium test failures came from device instability or OS issues.

But after analyzing dozens of projects, I found that over 70% of failures were caused by how we wrote and structured our tests—not the tools.

That’s when it became clear: Appium isn’t unreliable—our approach is.

Once we started using the right locators, adopting Page Object Model, running on real devices, applying smart waits, enabling parallelization, and tracking Appium logs, our reliability and execution speed improved dramatically.

Overview

Best Practices for Appium Testing

Parallelization
Use the Right Locators
Use Page Object Model
Run Tests on Real Devices
Use Wait
Use Appium Logs

In this blog, I’ll walk you through these core best practices that turn Appium from flaky to fast, scalable, and production-ready.

Best Practices: Testing with Appium

The following Appium best practices strengthen mobile automation by improving stability, reducing flaky behavior, and ensuring reliable execution across Android and iOS environments.

Parallelization

Parallel test execution increases test throughput and exposes device-specific issues earlier.

Significance:

Running Appium tests sequentially slows feedback cycles and hides platform variations. Parallelization distributes tests across multiple devices, operating systems, and versions, reducing bottlenecks and surfacing inconsistencies in UI behavior. It is especially useful for regression test cycles where execution time directly affects release velocity.

Apply in real user scenarios like:

A team needs to validate checkout flows across three Android devices and two iPhones before a production push and cannot wait several hours for sequential runs.
A CI pipeline triggers dozens of smoke tests on every commit; parallel threads prevent queue backlogs and ensure engineers get quick results.
A product team supports older OS versions; running tests in parallel highlights visual or timing regressions specific to certain builds.

Use the Right Locators

Choosing correct and stable locators prevents UI flaky tests and reduces maintenance.

Significance:

Poor locator strategies often cause intermittent failures when UI elements shift, animate, or render differently across devices. Prioritizing accessibility IDs, resource IDs, or stable attributes ensures selectors remain reliable even when layout or styling changes. This reduces the need for frequent script updates.

Apply this best practices in real user scenarios like:

A login button uses a dynamic index value on certain devices; tests break whenever the screen layout changes.
A developer modifies view hierarchy during a UI refresh, causing XPath-based selectors to fail across Android models.
A QA team encounters false negatives because multiple similar elements match the same locator during onboarding flows.

Jonathan Lipps – former architect and contributor of the Appium Project and mobile automation expert, explains that most flaky Appium tests stem from synchronization issues and brittle selectors rather than the framework itself.

Use Page Object Model

POM increases code readability and centralizes UI logic for repeatable tests.

Significance:

Page Object Model (POM) separates locators and interaction logic from test cases, making automation scalable and easier to maintain. Any UI change is updated in a single place, preventing redundant edits across test files. It also supports cleaner test scripts that focus on intent rather than low-level UI operations.

Apply this best practices in real user scenarios like:

A payment screen changes field names; without POM, dozens of test files require manual update.
Multiple teams contribute to the same Appium test suite; POM ensures consistency in locator usage and reduces merge conflicts.
New testers onboarding quickly understand page structures without deciphering scattered element definitions.

Run Tests on Real Devices

Testing on physical devices ensures accurate validation of performance and user behavior.

Significance:

Emulators and simulators are helpful in early development, but they cannot fully represent hardware-driven interactions, GPU rendering, battery constraints, sensor inputs, or OEM-specific quirks. Real device testing uncovers issues that synthetic environments fail to surface.

Apply this best practices in real user scenarios like:

A gesture-heavy screen scrolls smoothly on an emulator but stutters on mid-range Android hardware due to GPU throttling.
A camera permission prompt behaves differently on Samsung devices, causing tests to hang during image upload workflows.
A biometric login feature works on an iOS simulator but needs real-device hardware triggers for proper validation.

BrowserStack App Automate enables teams to run stable Appium tests on real devices at scale, helping catch locator, performance, and OS-specific issues early in the testing cycle.

Talk to an Expert

Use Wait

Proper waits prevent flakiness caused by asynchronous rendering or network delays.

Significance:

Mobile apps often load data progressively, animate transitions, or display dynamic elements. Hard-coded sleeps introduce unpredictability and slow the suite. Explicit waits tied to element states, activity transitions, or network conditions ensure interactions occur at the correct moment.

Refer to Appium Timeouts documentation here.

Apply this best practices in real user scenarios like:

A product list API call takes longer on certain network routes; tests fail because elements are not yet visible.
A multi-step onboarding animation runs at different speeds on iOS and Android, causing inconsistent tap timing.
A modal appears after a delayed permission check; without proper waits, the script attempts to interact with underlying elements.

Use Appium Logs

Clear logs accelerate debugging and help trace root causes of unexpected failures.

Significance:

Appium server logs contain detailed information about session creation, commands, responses, capabilities, and element interactions. Reviewing these logs helps pinpoint locator errors, capability misconfiguration, or timing mismatches. Logs also offer visibility into device behavior during complex flows.

Apply this best practices in real user scenarios like:

A script intermittently fails when launching the app; server logs show an incorrect package/activity configuration on Android.
An iOS test stops responding during a deep navigation flow; logs reveal repeated element search failures caused by a stale hierarchy.
A CI job shows inconsistent app launch timing; logs highlight delays triggered by background OS processes.

Keep Code Modular

Structuring tests into reusable components improves maintainability and reduces duplication across workflows.

Significance:

Mobile test suites grow quickly as features expand. Without modular design, shared flows—such as login, navigation, or API setup—get duplicated across multiple tests, increasing maintenance effort when changes occur. Modular architecture separates concerns into helper methods, utilities, configuration files, and reusable business-level actions, making updates faster and reducing the chance of inconsistent behavior across tests.

Apply in real user scenarios like:

A login workflow is used in 40+ test cases; a UI update to the login button requires modifying only one shared method instead of fixing every test individually.
A payment flow reused across checkout, subscriptions, and add-ons changes its security step; modular utilities ensure the new step is updated once and applied everywhere.
Multiple teams contribute to the same test suite; shared, modular components prevent conflicting logic and ensure uniform interaction patterns.

Use Consistent Naming Conventions

Clear and predictable naming helps teams navigate large codebases and understand test intent quickly.

Significance:

Mobile automation suites often include hundreds of test scripts, page classes, helper utilities, and element locators. Inconsistent naming slows onboarding, increases confusion, and leads to accidental duplication. Consistent naming conventions create an organized structure where tests, variables, and methods are easy to interpret, reducing errors during updates or reviews.

Apply in real user scenarios like:

A tester joins a project mid-cycle and can immediately understand methods like tapLoginButton() or enterEmailAddress() because they follow a standard format.
Locators named inconsistently across pages lead to accidental reuse of outdated identifiers; consistent naming eliminates ambiguity and ensures accurate updates.
CI failures are easier to diagnose when test names clearly represent workflows, such as test_add_item_to_cart or test_update_profile_picture.

Leverage Version Control

Storing the automation framework in version control enables collaboration, traceability, and safe iteration.

Significance:

Mobile test automation evolves with frequent code updates, device variations, and feature changes. Version control systems like Git ensure every modification is tracked, reviewed, and reversible. This prevents accidental overwrites, supports parallel development, and helps teams experiment safely without impacting stable test branches.

Apply in real user scenarios like:

A script update breaks multiple flows; version history allows teams to revert to a stable commit instantly.
Two testers working on similar modules create a merge conflict; version control helps detect and resolve inconsistencies early.
Feature-specific test branches enable isolated development until a new feature is ready to merge into the main suite.

Manage App State Efficiently

Controlling reset behaviors improves execution speed and ensures tests start from predictable states.

Significance:

Reinstalling the app or clearing data for every test run increases execution time unnecessarily. Using noReset=true or fullReset=false allows tests to resume from a signed-in or configured state, reducing setup steps and improving reliability for workflows that require consistent app data or user sessions.

Apply in real user scenarios like:

A sign-in flow requires OTP verification; setting noReset=true preserves the authenticated state so subsequent tests skip redundant login steps.
A shopping app needs the cart pre-populated for specific test paths; a controlled reset strategy ensures the cart remains intact between tests.
A mobile banking app test suite runs faster when onboarding screens are disabled after the first run, thanks to preserved application state.
