TOP 7 efficient app testing tools for 2021-22

Nowadays, we’re facing an exponentially growing number of apps. Only in the first quarter of 2021, the Apple App Store counted 2.22 million available apps, while on Google Play Market they were in a number of 3.48 million. (Statista)

Due to the fact that the competition is high, obviously, there is a huge demand on them to provide a top user experience journey. To ensure apps’ workability and efficiency, the development team, namely quality assurance engineers, continuously improve apps, fix bugs by regular tests. Clearly, tests are the key aspect that ensures apps’ security, scalability, functionality, accuracy, and many others that offer the user a great experience.

To run comprehensive app check, QA teams rely on manual testing, web testing, browser testing, regression testing, and API testing, and more. Regrettably, this process is time-consuming. Therefore, quality assurance engineers’ resort to certain tools in order to carry out automated tests.

To clarify which tools are more practical, more effective for testing applications in 2021-22, we realized comprehensive market research and came up with an integrated analysis on this topic.  You’re curious? Let’s see what each of them represents.

Selenium framework is intended for testing web applications on various browsers and platforms such as Windows, Mac, and Linux. Selenium helps QA engineers to write tests in different programming languages ​​such as Java, PHP, C#, Python, Groovy, Ruby, and Perl. Moreover, this tool offers recording and playback functionality for writing tests without learning the Selenium IDE (Integrated Development Environment). Selenium proudly supports some of the largest, well-known browser vendors who are confident that Selenium is a native part of their browser.

If we refer to its advantages, we emphasize the flexibility, additionally the ability to write complex and efficient scripts to test the applications. On the other hand, in order to start working with Selenium, the tester must have extraordinary knowledge of programming and be ready to devote some of his time and energy to writing special frames and libraries that provide specific functions during the testing process.

    Mobile app architecture: components and factors

    Today, due to the development of the mobile industry sector, companies have the opportunity to increase their businesses’ value by implementing mobile applications. But until you get a successful application, it is important to focus from the beginning on its architecture. Building clearly defined mobile app architecture it’s not an easy process, it heavily relies on a very meticulous plan, just like building a city. Due to this, you’ll save time, stress, effort, money because ahead a well-designed app’s architecture makes it easier for you to modify, test, and debug.

    ARCHITECTURE …? WHAT IS THIS?

    Being more explicit related to app architecture, we can define this as a roadmap and a detailed guide app of how the mobile app is supposed to be created. It consists of structural elements and interfaces, connections between selected elements, the general style of the program, and several layers, including:

    Presentation LayerBusiness LayerService LayerData Layer
    contains UI elements along with the parts processing them.consists of workflows, business entities, and components.is made up of service interfaces and message types.involves data utilities, data access components, and service agents.

    Once you have decided to create an application, invest time and money in its architecture. Focus on its convenient functionality, rapidity, safety, and excellent structure. Firstly, start by checking key principles that a mobile app architecture should include:

    1. Efficiency. The application performs the assigned tasks and performs the functions in any conditions. The system is efficient, reliable, and can handle all loads.
    2. Flexibility. The solution you choose is easy to change and there are fewer mistakes. You can change one element, and this will not be fatal to other components.
    3. Extensibility. You can add as many features as you like to your application if required.
    4. Scalability. Development and addition time is reduced. A good architecture allows you to streamline development into multiple parallel threads.
    5. Testability. You are able to test each component separately, to allow future consistency to diverse variables.
    6. Manageability. You monitor the workability, functionality, security, and efficiency of the system.
    7. Reusability. The elements and structure can be reused in other projects.
    8. Maintainability. Due to market conditions and consumer behavior continuous changes, architecture should always have the capacity to be changed, corrected, modified, and improved.
    9. Comprehensibility. The code should be understandable to as many people as possible. A lot of people are working on the application. A good architecture allows beginners to quickly understand a project.
    10. Performance. Ensure quick response to users’ intent/request during app usage. Therefore, we provide amazing customer satisfaction, without resorting to the app uninstalling and customer loss.
    11. Security. The architecture should be maximum robust to fully secure and protect user data and data which is used by the app.

    Then, based on the target audience, platforms it’ll be deployed on, features and functionality, correctly choose the right type of your mobile application:

    • NATIVE APP

    is a program for iOS, Android, and other platforms. Native means the app is built for one platform.

    + efficiency due to compliance with all the requirements of the selected category of devices;

    + more secure;

    + has better performance as compared to a hybrid app;

    + interact with other native APIs;

    + doesn’t depend on plugins and WebViews;

    + perform much faster as compared to a hybrid app;

    + quick access to new features;

    + better user engagement;

    – two separate codebases and databases – one for Android and the other one for iOS;

    – require installation;

    – difficult to run SEO campaigns and strategies;

    – costs (time/budget).

    • HYBRID APP

    a site optimized for use on a mobile device.

    + reduce development time and costs;

    + leverage cross-platform capabilities;

    + work on multiple platforms;

    + less time-consuming to create;

    + automatic updates;

    + easy maintenance;

    – requires a constant Internet connection, because it is located on a separate server in the network.);

    – limited user interface;

    – depend on the browser’s speed.

    and:

    • bandwidth scenarios;
    • user interface;
    • navigation methods;
    • the device types:
    ANDROID APP ARCHITECTUREiOS APP ARCHITECTURE
    For the Android mobile architecture app, a good solution is the Clean Architecture because it makes your app more independent of frameworks, databases, layers, and more. In other words, your developers will not be tied to a specific framework or database. Also, we use, MVVM, MVP, MVI.

    Deciding architecture type, pay heed to android frameworks, libraries, app developing concepts, app components, and fragments to provide an ideal approach and an outstanding user experience.
    For iOS, you may find suggestions from Apple to use the MVC (Model-View-Controller), MVVM architectural pattern for UIKit, but again, you need to understand and carefully analyze every detail to realize which kind of architecture will make the best version of your app.

    We at DAS Solutions design mobile applications using the following methods, depending on the project objectives:

    MONOLITHIC ARCHITECTURE

    The necessary logic is stored on the server, and all the necessary information for the server is stored in the database. Such applications are very simple and require relatively little development time. But in the long run, applications are bound to change because they have to fit new platforms, gadgets, and operating systems.


    MICROSERVICES ARCHITECTURE

    This is typical for cloud-native applications, which are now popular due to the advantages that cloud environments provide for business. It is a method of building independently developed and distributed applications, each of which runs as one or more isolated processes.


    For any changes, even the smallest, monolithic applications require rebuilding and deploying the entire monolith. Whereas microservices are broken down and placed independently of each other. This means that microservices offer a completely independent approach, with each individual component performing a different function for the entire system to work.


    SERVICE-ORIENTED ARCHITECTURE

    SOA is independent of the programming languages, platforms, or protocol specifications used for services developed. Also, an important aspect of SOA is high flexibility, which is achieved due to the ability to quickly adjust business logic – a change made to a business function will eventually affect all the necessary applications.


    With the increasing complexity of applications, some modules are moved to separate hardware parts and services. Modules here sometimes hold their own databases and reside on separate devices. This has its pros and cons.
    Such an architecture requires serious investments at the start, but with a competent approach, costs are reduced at subsequent stages of development. Service-oriented architecture is good for large companies.


    Before developing your mobile app architecture, consider some important factors and elements like:

    Device Types

    • Screen resolution;
    • Screen size;
    • CPU Features;
    • Storage Space;
    • Memory;
    • Availability of the development framework.

    ✓ Bandwidth Scenarios

    • with an internet connection (3G, 5G);
    • offline connection.

    ✓ Navigation Methods

    • Stacked navigation bar;
    • Navigation bar (top and bottom);
    • Tag driver;
    • Modular controller;
    • Single view;
    • Scroll view;
    • Gesture-based navigation;
    • Search-driven navigation.

    ✓ User Interface (UI)
    ✓ Real-Time Updates vs Push Notifications

    It might look difficult to plan the architecture app, and it is we confirm, this is why we recommend to work with an expert software development company.

    DAS’s architects are experienced and qualified specialists who work in tandem with programmers, coming with advice to developers related to the app and giving instructions on how to create an app. At the same time, the architect is looking for compromises between customers, managers, developers.

    We know how to create a fast and reliable architecture, providing a unique user experience. Designing mobile applications is our specialty. Contact us by email and let’s speed up your mobile app architecture.

      Your Business Can Be So Much More With the Right Software Tools

      Companies are looking for a strategic partner that provide software platforms which impact their day-to-day business workflows and will positively affect their bottom line.

      Mobile Applications Used in Business: Convenient and Simple

      Mobile applications used in business improve the workflow inside the company, and have a beneficial impact on customer service and customers’ loyalty. More and more small and mid-size businesses understand the mobile trend and the fact that they need more than a website and a profile on social networks. Customers are overloaded with information and you need to add value to catch their attention and win their affection.

      Mobile applications used in business are a necessity, because they can:

      • provide customer service (e.g., banking or shipment tracking apps)
      • give value added benefits (e.g., retail apps can use a reward program)
      • bring convenience (airline apps allow you to change your flight or buy another ticket quickly)
      • send push notifications to let your customers know about a promotion you are running
      • bring additional revenue (your company can sell the premium version of the application)
      • accelerate mundane tasks
      • provide access to information when the employee is not in the office (e.g., access to CRM and databases).

      A survey conducted by Canvas has shown that employees used from 1 to 5 business mobile applications in their work in 2014, while in 20% of the companies surveyed, employees used more than 10 apps in their work. Canvas has found that companies are saving a lot of money by using mobile applications that reduce manual processes. Also they have found that signature and image capture are the most popular features in business.

      There are many mobile applications used in business, however if a process has to be simplified then it is close to impossible to find an application for that in an app store. In this case you need a nice and intuitive custom application developed with your process in mind. Let’s say it takes a lot of time to do a certain task, because the employee has to be outside the office and has to fill in a lot of vital, accurate information once he or she is back. If the task is completed on the go then the information stays error-free and it takes less time to complete the task. If your staff uses a custom enterprise application, then you will outperform your competitors.

      Your business can streamline business processes, eliminate paperwork and make your customers loyal. Contact us to get an estimation for your custom mobile app.
