The mobile app testing checklist. When testing smartphone devices, keep those 3 points in mind.

Mobile apps are now experiencing such a boost that their success cannot be overstated. About every company needs a smartphone app: social and texting, finance, food ordering, and shopping. Of course, we want them to work perfectly and quickly. But how can you be confident because there are thousands of different mobile device types and platforms to choose from? We’ve created smartphone app review guidelines to make it a little smoother.

Mobile application testing checklist:

Various ways of data input

The vast majority of mobile apps follow a basic rule: users input data (text, images, and videos) in some form, which is then processed through different operations. If your software falls into this category, you can ensure that it can perform the following during mobile app testing:

  • When a keyboard is invoked, it appears with the required layout.
  • Inputs that accept both typed and pasted text. While you’re there, take a look at the autocomplete and autocorrect choices.
  • One or more fingers are used. The program should be able to recognize and respond to appropriate movements or commands. Tap, double-tap, press and hold, multi-touch, swipe, pinch, and other common commands are included.
  • the phone camera. If necessary, the app’s camera should be able to recognize barcodes or QR codes in addition to taking images and videos. In the case of devices with multiple fronts and rear cameras, the appropriate one should be launched by the application by default.

Screen orientation

Screen orientation is the second item on our mobile app review checklist. The device’s sensor can sense when the phone’s orientation shifts from vertical to horizontal (known as portrait and landscape). This often necessitates a major shift in the application’s architecture, which is crucial in mobile app development.

For cosmetic or technical purposes, certain applications on the market do not allow screen rotation. If the application must be both horizontal and vertical, you can test it many times to ensure that the rotation of the interface between the two, as well as any adjustments made during the process, do not result in:

  • the data entered by the user would be lost by the application.
  • the application’s condition to be changed.
  • After saving, the data does not fit what was shown previously.


Any of the smartphone application’s features require access to the device’s basic features. Allowing the app to use the camera or photo gallery is needed if you want to post a cute selfie with your cat on Instagram. Contacts or a microphone are two other common accesses needed by certain applications.

However, the issue of permission does not exclude your users from accessing the application’s other features. Members of the aforementioned Instagram should be able to access their photo feeds and watch stories without experiencing any issues.

When testing permissions/accesses, you should take into account whether:

  • There are no defects in the application’s daily service when access is restricted or denied.
  • The program only requires the approvals that are needed for its regular service.
  • The failure of an application is not caused by refusing any permissions during installation.

React Native Vs Flutter-This distinction could alter your approach to app development

The mobile application development environment is being conquered by cross-platform frameworks such as Xamarin, React Native, Flutter. It is capable of operating on various mobile platforms. It allows startups to save lots of costs and reduce development time. Generally, once you build a native app-you need to build a separate one for IOS and a separate one for android. But within the case of Cross-platform apps, you’ll create an app that will target both Android & IOS Devices. Cross-platform development provides the pliability to make your app employ a universal language like Javascript. you’ll likewise export your app to varied smartphone platforms with Javascript.

What is Flutter?

Flutter may be a free and open-source mobile UI framework created by Google. Flutter aims to provide an open framework to create beautiful native apps on multiple platforms quickly. Flutter allows you to make a native mobile application with just one code. It means you’ll use one programming language and one codebase to make apps on IOS and Android at an equivalent time.

What is React Native?

React Native is an open-source mobile application, Facebook makes the system of React native applications. React Native is compiled from one JavaScript codebase. It enables code reuse between android and iOS. It covers a huge scope of platforms like IOS, Android, Android TV, windows, and UWP. React native joins the right aspects of local advancement with React, a top-tier JavaScript library for building UIs.

Flutter & React native backed by Google & Facebook, severally. That’s why we witness the tough competition between Flutter & React-native nowadays. If you would like to make an app in iOS or android React Native and Flutter are the highest mobile frameworks nowadays. These frameworks are the gossip amongst the developer community, with tons of competition and comparison between them in recent years.

It is tough to mention which one is the best, but from browsing the below-given points you’ll choose appropriate app development software as your requirements.


Flutter & React native extensive 3-way layered system. There exist a series of independent libraries that depend upon the underlying layer. Every part of the framework level is meant to be optional and replaceable, Each layer has its importance & utilization.

  • Framework
  • Engine
  • Embedder

Flutter’s design is stratified. Flutter uses Scaffold that runs by a C/C++ engine and a platform-specific embedder. In short, Flutter has everything required for app development among the Flutter engine itself.

On the other hand, React native ties the knot between the native thread & Javascript thread. Android & iOS respectively use JavaScript Cores & Bundles of JS Cores to run all the codes easily. While this might increase the native functionality, it also increases the app size, resulting in performance issues or device lag.


Flutter uses dart programming for writing their codes. Although Dart is relatively easy to pick up and a far better programming language. A developer sitting on a plane has got to travel through Dart. Typically, developers from a C++/Java background can relate to Dart quite JavaScript developers.

React Native is written entirely within the JS framework. This is often a plus point for React Native since JavaScript consistently ranks together as the foremost popular and used programming languages around the globe. Finding developers to code in JavaScript is straightforward, and hence learning React Native is simpler for any JavaScript developer.


The respective community of both RN and Flutter are a touch divided over the subject ‘performance’ as everything about them sounds good in terms of agility and speed. But Flutter has the whip hand because it doesn’t have a JS connection bridge-like React native. In Absence of Js Bridge in Dart- Flutter is better than React native in terms of performance.

IDE (Integrated Development Environment)

Flutter is more targeting working with Intellij, Android studio & Visual studio(These are the trending IDEs). These IDEs are the simplest for the developers that employ flutter. Few plugins are required to figure on IDE with Flutter.

React native is especially focused on working with Nuclide, Atom, & Webstorm. Since React Native is open-source, the simplest IDE or editor is the one with a broad deployment. you want to also confirm that each one of your supporting tools and software are widely used while working with React native.

Community Support

In React native you won’t find any appropriate guide for deploying an app to the App Store. On the opposite hand, Flutter gradually grows with the trend as CLI (Command Line Interface) most ordinarily used for deploying your application simply in Flutter. consistent with some Significant data/insights on various platforms like StackOverflow, Google trends & Github analytics- you’ll likewise compare the react-native & Flutter.


In general words, we can say that documentation is the inventory of knowledge. Your framework Documentation should be easy & simple. you’ll easily explain it to your client or other developers can easily understand the info written within the documentation. React Native has decent documentation. It mainly focuses on senior web developers who are already conversant in JavaScript & Coding. Contrary to React Native, Flutter has rich documentation. It offers detailed guides amid graphics and video tutorials.
