Before we start the mobile app testing process we should know about what is mobile app testing first.
Mobile app testing is the process of testing the functionality and usability of the mobile application to make sure that it meets the requirements and that the application is ready for launch.
What are Mobile application testing requirements?
In a mobile web application, the Website opens on the device with the help of the mobile browser. The Mobile web app does not require any installation.
The native application is specifically developed for one platform (iOS, Windows 10 Mobile, Android)
A hybrid application is the combination of a mobile web application and a native application. It can be defined as mobile website content shown in the application format.
Before starting testing, we are required to plan what we have to test and for planning the test to analyze the requirements.
Before testing any mobile apps, we identify what testing is required to test the particular mobile app: functional, usability, compatibility, performance or security, etc. And also determine what functional requirements should be tested.
Identify what target devices to include:
Make a test case document for each and every feature and functionality.
Make separate suites for manual test cases and automated test scripts as required. Make typical sets for manual test cases and automated test scripts. Define any reusable automation scripts and modify them as per the project requirements.
Download, install, and configure the particular application on the different mobile devices to set up the testing environment. Before starting with the actual testing make sure the test version of the application is established.
We are required to execute both manual and automation test cases.
You have already identified and created which tests and scripts to use. In this phase, you’ll actually run these on the basic functionalities to ensure that there are no bugs.
The usability testing purpose is to uncover how much the product is easy to use, understandable, is it able to satisfy the user’s needs impressively. Usability testing is the way how output can be used by users to reach specified goals.
UI testing is one of the very important tests in mobile application testing.
Some characteristics that should be tested for every app:
Common screen resolutions are:
Verification must be done starting from the smallest to the biggest resolution. If the application has a large list of cards with information then those also need to be tested on a different resolution for their information wrapping.
There are too many variations in screen sizes in smart devices especially.
Make sure the control size looks good and the control is properly visible on the screen while testing.
Test the application with different browsers, mobile devices, screen resolutions, and OS versions as per the requirements.
When the regression testing is completed by the QA team, the build moves to User Acceptance Testing and this is done by the client. They make sure the application is bug-free and working as expected on every defined browser.
Performance Testing of the application using changing the different connections from 2G, and 3G to WIFI, responsiveness, battery consumption, stability, etc.
Test the application to measure scalability and performance issues.
Localization Testing is used to test making a product, application, or document content adjustable to meet the cultural, lingual, and other requirements of a specific region or locale.
In Security Testing, ensure that the application is secure by validating SQL injection, data dumps, session hijacking, packet sniffing, and SSL.
When a device is tested ensure that it is working as expected.
Execute test cases and scripts in all the devices, in the cloud, and/or in physical devices in the lab or via testing tools.
