A quality analyst has a very difficult job. They are frequently despised by developers since no one enjoys hearing that their code is flawed. However, the work of a QA is highly crucial and rather interesting in the process of developing software. A QA plays a crucial function, particularly in the current era of digital transformation, when the number of smartphone users is growing every day and businesses are increasingly turning to the development of mobile applications. based on the end user’s device or browser, an app’s behaviour may vary based on its functionality or user experience. Let’s talk about the manual testing techniques required to guarantee a mobile application’s successful, defect-free deployment.
choosing a device type
Identifying the number of devices that will be used for testing is a crucial task before the testing process begins. The number of iOS-compatible devices is constrained. The platform or device on which Android can be installed, however, is not constrained. This has led to the presence of hundreds of Android smartphones, each with a unique UI and screen resolution. It will also be better.
- Utilizing analytical tools, conduct market research to identify the devices that end customers like to use with the kind of application you have created.
- For your mobile testing team, get a few Android and iOS devices if the project budget estimate is adequate.
- The default emulator in the browser or mobile device emulation plug-ins will do for UI testing since functionality testing is covered in genuine mobile devices.
Emulator or Device: Which Should I Use?
You must make the following important decision after conducting a market study and selecting the devices for testing. Whether to test on actual devices or browser emulators. Let’s talk about the benefits and drawbacks of each.
Real gadgets are:
- The identical hardware and operating system that an end user would employ can be used for testing.
- You can also test an application’s performance when it is being interrupted by a voice call or SMS.
However, there are drawbacks as well, such as
- Cost of purchase and upkeep.
- Devices that are available but are only used in specific nations.
On the other hand, emulators are
- Easily accessible, with the majority being open-source and free.
- Expected actions are simple to locate.
- They are able to be connected to an IDE during the development stage.
- Functionalities of both software and hardware can be duplicated.
There are also some drawbacks.
- It is impossible to simulate real-time events like device heating or battery loss.
- more slowly than the actual equipment.
- Not every OS version is supported.
a cloud test
In-house solutions work well for unique testing needs. But in the recent era of digital change, the Cloud offers us a variety of testing options.
- By doing testing on a cloud platform, the issue of procuring various devices and maintenance costs can be avoided.
- Multiple places can access the device pool.
- The main benefit is consistency. It is possible to redeploy and run test case scenarios each time the developer edits and adds code.
- By improving test coverage, the application’s quality is ensured.
- allows for the simultaneous execution of the same scenarios across numerous devices, supporting parallel test case execution.
It’s crucial to evaluate how the application works in an area with spotty network coverage before releasing it live in production. Testing the application on actual hardware with various network connections is challenging and time-consuming because connectivity varies by location and network providers. Another solution is offered by cloud testing, which gives users the opportunity to simulate various connectivity ranges.
Browser compatibility and user experience
It is preferable to carry out UX testing on genuine devices. The test should be performed manually.
- Button, dropdown, and other application component responsiveness to touch.
- Animations, page changes, and reaction times that are specific to user activity.
- responsiveness of the viewport on many platforms with various resolutions.
- If the program is web-based, it should be tested to see how it behaves and how well it performs in main Android or iOS device browsers.
Testing for performance and security
Storage space on mobile devices is constrained. When the mobile device’s storage capacity is getting close to being filled, applications frequently become sluggish or unresponsive. The application needs to be manually tested to see how it works on a device with limited storage. Additionally, testing should be done to see how it functions as the number of users increases if it generates files like photographs or reports.
Out-of-the-box security testing concepts are necessary if the app handles sensitive data like banking or online transaction-related information. It should be made sure that the app doesn’t save any data to the device in particular. It can be quickly tested by:
- launching the program and signing in.
- Close the browser window or click again.
- Reopening it to see if the user is still signed in.
Testing mobile apps manually is not glamorous. It is, nevertheless, a difficult job that occasionally calls for the tester to come up with an original idea. Mobile consumers are typically intolerant, so if they see an application isn’t operating as expected, they’ll delete it right away. Therefore, a successful manual testing method is essential to the success of an application.
