Building a Practical Mobile Test Plan: Plan Outline

What a Mobile Test Plan Brings to QA

Mobile applications operate in a fragmented and demanding environment. Unlike desktop software, which may only need to account for two or three operating systems, mobile apps must work across dozens of devices, screen sizes, hardware configurations, and network conditions. Add to that the pressure of rapid release cycles and user expectations for seamless experiences, and the margin for error is small.

This is where a structured mobile test plan proves its value. A test plan is more than a checklist. It is a living framework that guides teams through installation checks, performance baselines, compatibility tests, and real-world usage scenarios. Without it, testing risks becoming ad hoc, missing critical cases, and consuming more time and resources than necessary.

Well-designed test plans also create a shared reference point between development and QA. They make it clear which areas are in scope, which are most critical to business outcomes, and how success is defined. This clarity helps prevent late-stage surprises and supports more predictable delivery.

A Comprehensive Mobile Test Plan Outline

Below is an expanded test plan outline that covers both mobile and desktop considerations. It highlights the breadth of areas a QA team should address, from installation through security validation.

Here we show you a Mobile Test Plan Outline and the items to check for Desktop and Mobile applications.

Test Category	Test Area
Installation	Install App via computer link (i.e. iTunes)
	Install App via download internet link (i.e. Web App store)
Exploratory Testing	Launch application in target language
	Ensure that application starts up properly on launch
	Check that orientation is correct on launch.
	Check for application stability
	Launch and close 5-10 times or more
	Install App in different location other than default
	Download an update
	Check graphics appearing in:
	a) Splash/Title/Logo/Loading Screen
	b) Main Menu and all its subsidiary menus
	c) Help/Instructions Screen(s)
	d) About screen
	e) Application Pause Menu and all its subsidiary menus (if present)
	Uninstallation
	Install when disk is full
Spelling Errors	The application must be free of spelling errors.
	A spelling error is defined as a strict misspelling of a word (no grammar or punctuation rules will be applied). Missing diacriticals and accents (e.g. acutes, cedillas,umlauts etc) will not be reported as spelling errors.
Technical Text Errors	The text in the application must be clear and readable.
	The application must be free of technical text display issues such as: Text cut off / Text overlapping
Application Response	The application should never leave the user in a position where the state of the application is unknown or appears to be unresponsive (i.e. may have locked up).
Speed & Performance	The application works in the device it was targeted for. It is usable on the device. The speed of the application is acceptable to the purpose of the application and must not alter the user experience by being uncontrollable.
Unexpected Behavior	The application must be able to handle unexpected user behavior, for example erroneous actions and multiple key presses.
Conflicts/Interrupts	An incoming call/video call while using App
	An incoming SMS while using App
	Pause and launch music/movie player
	Pause and launch camera
	Pause (or not pause) and launch another app
	Low battery when using app
	Plug or unplug USB when using app
	Change USB connection when using app
	Close/Lock screen and open when using app
	Close mobile before quit app
	Minimize the app to status bar and launch it
	Switch to another app, then launch this app from status bar again
Storage	Disk usage
	Memory usage
	Run App for long time and check memory usage
	Use when disk is full
	Save/Load process when using
	Synchronize with computer (if applicable)
	The application must indicate whether data will be permanently deleted or offer easy reversal of the deletion.
	Ensure Updates does not corrupt current save data
Signal and Network Performance	Using with 3G signal
	Using with WIFI signal
	Verify Bluetooth transfer and connections (if applicable)
	Use with intermittent signal
	Using under weak/no signal (such as in high speed car, basement)
	Check GPRS data usage
	Application that uses network capabilities must be able to handle situations where the network connection is not allowed.
	Application that uses network capabilities must be able to handle delays and any loss of connection.
	Application that uses network capabilities must be able to use the connection correctly and correctly close it after using it.
User Interface	Check all Function keys on mobile for both touch screen and keyboard
	Check UI consistency
	From very small to tablet size screens, check UI for incorrect handling of components
	When zooming in or out, check UI for incorrect handling of components
	Check each input methods: both touch screen and keyboard
	Check 4/5 finger gesture scrolling if available.
	Check swiping consistency and awareness
	Check that GameCenter feature functions if available.
	Check that Facebook feature functions if available.
	Check that Twitter feature functions if available.
	Check that the e-mail functions if available.
	Check that in-app purchases functions and no errors occur prior to and or after purchase.
Compatibility	Run on different OS
	Run on different devices
	Change mobile’s time/time zone/date
	Check after update OS/firmware
	Switch to different languages
	Change mobile’s time/time zone/date
	Check after update OS/firmware
	Switch to different languages
Other	Find-ability/Usability for all items
	Response time for each critical tasks (performance)
	File format support
	Error prevention and detection
	The application must be able to handle the cases where the connection to the PIM applications is not allowed.
	When connections are used, encryption is used for sending/receiving sensitive data

 

Items to Check that are the same for Desktop and Mobile
Login/Logout	Login with correct/wrong password
	Logout
	Change password
	Password display (Encryption)
	Security validation
	Logout and Login with multiple accounts
Website	Launch by different browsers if needed
	Check the look time and load time
	Check consistency between mobile site and regular website
	Launch different version of browsers
Text Entry	Switch different input methods
	Check association for each input method

Making the Test Plan Work in Practice

Having an outline is only the beginning. The effectiveness of a mobile test plan depends on how it is used and maintained. Some best practices include:

• Prioritize by risk: Not every test carries equal weight. Focus first on core user journeys and business-critical features.
• Test in realistic environments: Emulators are useful, but real-device testing is essential for accuracy. Include different network conditions, battery states, and interrupt scenarios.
• Balance manual and automated testing: Automation is invaluable for regression and repetitive checks, but manual testing is critical for usability and exploratory coverage.
• Update continuously: Mobile ecosystems change quickly. Review and revise test cases after each release to ensure relevance.
• Document and share: A test plan works best when it serves as a common reference. Keep it accessible, version-controlled, and integrated into team workflows.

By embedding these practices into your testing process, the outline above becomes a powerful tool rather than a static list. It helps ensure coverage, reduces duplicated effort, and aligns QA with business outcomes.
