App crashed! Taking too much memory! Data Transfer error! Phone hanged at call interruption! Cannot retrieve GPS location! Complicated UI! Unable to install updates! Poor graphics! Functional Errors! Data loss! Network connectivity issues! Blah…Blah…Blah…I guess you understand the need for different Mobile App Testing Types 😉
Mobile App Testing Types
Yeah! These are some of the common App errors that force Users to dislike & eventually uninstall the App. Multiple Operating Systems, Devices, Network operators and interfaces increase the risk of failures, if not tested properly. Keeping in mind the permutations & combinations involved in Mobile App testing, let’s try to answer the basic question – Test Coverage – or the Mobile App Testing types required to get that awesome App experience.
The most important tests for ANY software – whether it functions as per the requirements / User needs? What if a User is unable to make a payment using your e-commerce App? Every other Mobile App Testing comes next!
First the App has to be installed on a smartphone, except Web Apps & pre-installed Apps. User should be able to Install, Update & Uninstall the App without any issues.
One of the major feature that sets Mobile App apart from a desktop application is its usability. Rendered on a handheld small screen with touchscreen navigation, Usability is the first thing a User would notice when using the Mobile App. Is the app intuitive to use? It’s the key to commercial success. Mobile App Testing for Usability covers checking App’s User friendliness, ease of navigation & usage, Uniform User experience across devices, UI layout and design, etc.
One of the major Mobile App Testing type – verifying that the App is compatible with different Mobile devices, Operating systems, Browsers, Screen sizes, Interfaces and Network operators.
Is the App responsive? I.e. quick processing of User actions. Concurrent Users, Long App usage, multiple transactions, Battery usage, Data consumption, processing power, Network variations (2G, 3G, and Wi-Fi) and Application speed are few examples of performance test parameters.
Contacts, Photos, Messages, etc. are something very personal to a Mobile User. Security checks are important for Mobile App Testing strategy to check for vulnerabilities to hacking, authentication and authorization policies, data security, session management and other security standards.
Can the App suspend & resume in case of interruptions (which are highly probable)? E.g. Incoming or Outgoing SMS/MMS, Incoming or Outgoing calls, Notifications, Battery Removal, Cable Insertion and Removal (for data transfer), Network outage and recovery, Media Player on/off, etc.
Backups and recovery plan if battery goes down, Data loss while upgrading the application, App behavior during low battery or bad network, Offline usage, Voice and/or Data connection usage to perform specific functions and using external features like GPS, accelerometer, sensors are just few examples of operational tests.
App Life-cycle & Regression
Agile development, near real-time resolution of bugs and feature updates lead to newer versions of App being released frequently. With each App Update, a round of regression Mobile App Testing ensure that the original functionality & features are not impacted.
What would your ‘Map’ App do if a GPS signal was lost or couldn’t be obtained? What if there is no Data connection? Using camera when battery is low? An awesome App is not just about the functionalities & UI – Error handling is also inbuilt to ensure User is not upset or frustrated with the App (in some exceptional error scenarios).
This is my list of basic Test coverage for ANY Mobile App Testing strategy. On top of this, there might be some other Testing Types required based on the specific ‘App’ under test. With over 40 Lac Apps already in Market – a strategic Mobile App Testing approach is a must if you want to build an ‘Awesome App’ that stands-out from the rest.
I know this is not an exhaustive list of App Testing Types, which means I would love to read your thoughts on it…Please reply below & help the Mobile App Testing community!
