Testing Flutter Applications Quality Assurance

An integral part of the development of any application is the testing phase or Quality Assurance (QA). This approach ensures the high quality of the software product, helps to identify and eliminate errors in its operation, checks scenarios under valid and invalid conditions of use, and also determines the level of release readiness.

The Flutter framework allows you to create high-performance and reliable mobile applications without using native components. During their testing, the following are subject to verification: software functionality, usability, performance, speed and security level.

Features of testing Flutter applications Flutter

Flutter is a cross-platform framework and allows you to compile the created project for three operating systems: iOS, Android, and Fuchsia. It uses the Dart programming language, whose syntax is very similar to that of Java.

All Flutter applications include one or more widgets – instances of classes that allow you to create text and images on the screen. These features are necessarily taken into account by QA specialists when checking software.

Despite the variety of Flutter applications, the developers adhere to the following algorithm when testing:

Functional testing – checking that the program meets the requirements. Experts consider the correctness of the main functions and capabilities of the product, as well as the operation of system processes.

All interface elements, the logic of transitions across screens, forms and fields, buttons, the process of installing and launching an application, power consumption and response to interruptions are tested.

Usability testing is a technique for testing an application for usability. Its structure, interface components and software compliance with the specified specification are assessed.

At this stage, the following aspects are checked:

  • simplicity and clarity of navigation;
  • whether the app provides a positive user experience
  • compliance of the design with the functionality specified by the customer;
  • correct passage of user scripts;
  • quality and availability of content;
  • compliance of the product with key performance indicators.
  • Performance testing is a set of measures aimed at determining the health, stability, response speed, resource consumption and other attributes of the application quality.

During testing, various use cases and load cases (to identify peak) are applied, opportunities for further scaling are evaluated, etc.

  • Compatibility testing determines whether the application works correctly on gadgets of different models, with different versions of the operating system, as well as whether it is displayed correctly at startup. During validation, QA specialists use different devices to quickly identify errors and optimize the product.
  • Security testing is aimed at finding, detecting and fixing defects related to the storage of user data. Attempts to find out the password using external means, system attacks using utilities and other means are prevented.
    For this, an analysis of the application architecture, building a threat model and a risk matrix, searching for vulnerabilities in the source code, load and dynamic testing is used.

Flutter allows you to create all elements of the application’s user interface from ready-made widgets, so special attention is paid to widget tests (or component tests). Their purpose is to prove that the widget interface looks and interacts with the user without errors.

The simplest method for testing software products is unit testing. It relies on ensuring that a piece of code (function) or class method is correct. This method has one significant drawback: it does not reflect the real environment, therefore it is usually used in conjunction with other types of testing.

Integration tests are another form of UI validation. Unlike widget tests, they evaluate all the functionality of an application or a significant part of it. The goal of integration testing is to make sure that all services and widgets work together correctly.

Benefits of testing Flutter applications in AVADA MEDIA AVADA-MEDIA

AVADA MEDIA offers services for the development and professional testing of Flutter applications for various fields and areas, both manually and using proven automation tools.

The main goal to which our specialists strive is to create a universal software product that fully meets the needs of the user and the wishes of the client, as well as provides a positive experience when interacting with him.

In addition to checking the quality of the application, testing also performs other important functions:

  • detects errors and problems in the operation of software;
  • checks the display of interface elements on various devices, with different OS and screen resolutions;
  • determines the effectiveness of the application under conditions of increased load;
  • evaluates the interaction of modules within a system or between several systems;
  • identifies redundant transactions, compares conversion and real user routes;
  • eliminates performance defects;
  • minimizes the likelihood of data corruption and theft.

The team of QA engineers of AVADA MEDIA conducts a full cycle of application testing (on mobile devices and emulators), covering all the main stages of project development: from requirements analysis at the software design stage to final tests before release and promotion on the market.

We develop high-quality and stable products aimed at scaling and increasing the efficiency of our clients’ business.
