Full Life Cycle Software Testing

XB Software renders software quality control services, which inlude full lifecycle testing covering the core stages of development starting from requirements testing at the software design stage and completing with final testing at the release and deployment stage. Below you will find description of all types of software testing services we offer.


Requirements testing covers testing of requirements specification as well as assistance in collection and analysis of user data, their domain (area of activites) to research interface usability, profile creation, clarification and shaping up of documentation. Also, it inсludes assistance in the design of project.

This procedure allows improving requirements quality and reducing the number of tests necessary to meet these requirements.


The most important part of software development process is elaboraton of requirements and project design.  Errors discovered and eliminated at theses stages will help decrease software developent time and cost greatly.

Prototype testing allows diving deeply into the future project from the very beginning and making amendments in accordance with product business requirements. It should pass prototype testing to make sure it will work as expected when released. Besides, your prototype will be tested for safety issues to eliminate any risks associated with the product or its misuse. It is also tested to comply with international standards. Most importantly, prototype testing allows assessing the potential production costs on each stage and choosing the most efficient development process.

If you have mock ups or design sketches that are used during project design, they can undergo testing of user interface. The prototype is tested for critical design flaws and ease of use by customers to make sure that it works the way it should. Our quality assurance (QA) team will evaluate your prototype and make suggestions on how to improve it to make your product more user-friendly. This stage can involve focus groups, when required.

To create the product you need, it’s important to document all testing steps. Creation of test documentation will considerably raise the product quality due to closer cooperation, details confirmation while preparing documentation and testing plan. When testing is completed, you may then check off whether all the testing steps were successfully completed.


Unit testing allows scrutinizing individually all small testable parts (units) of your software to check out whether they operate properly. Unit testing is a top-priority testing that involves negative and positive testing of newly-added software functionality during development process.

Integration testing allows you to test how larger app components are interconnected and identify any defects emerging during units integration. This type of testing shows whether the integrated units work in an error-free manner. After all untis are tested for proper integration, we proceed to system testing.

System testing is conducted to explore system functionality. It is carried out during each build and during release stage as alfa and beta testing of the product. For bigger projects it usually consists in creating use cases. System testing covers all aspects of a software system’s performance, its functionality and reliability. It involves testing for compliance with functional and non-functional requirements.

An excellent solution to do regression testing in terms of a big and a long-term project with diversified functionality. We use continious integration (CI) tools such as TeamCity that provides on-the-fly tests reporting and supports different frameworks to automate testing of web applications. We use TestNG and WebDriver for this purpose.


At this stage we test UI user-friendliness and its correspondence to the design requirements and mock ups. We check out whether the app behaves as expected and returns the correct UI output when a user performs some actions in it.

This helps improve the software quality and its usability.

To test user interface we conduct focus groups with potential clients.

User interface testing is directly related to cross browser and cross platform testing.

A variety of operating systems and browsers causes a huge problem for an app development and support. Cross browser and cross platform testing ensures that the working out software operates across all browsers and platforms equally good. Knowing your target audience, we can focus on testing your app in specific test environement.

A great number of applications are designed to be used by many users. This creates additional load and stress on the app parts. Emulation of stress before product release allows identifying the weakest parts of the app. It involves quantative tests (errors frequency or system crashes) and qualitative tests (resistance to DoS attacks).

Other testing services

We also offer additional types of testing. They are aimed at more detailed testing of your product to facilitate its successful promotion on the market.

By type

Functional testing is carried out to define how a component or system meets the set functional requiremetns described in specifications.

This type of testing can be done on all testing levels: component, integration, system and acceptance testing, i.e. on all stages of software development.

Non-Functional Testing – testing of properties which don’t belong to the system functionality. This type of testing covers performance testing, stability and reliablity testing, installation testing, configuration testing, failover and  recovery testing, etc.

By application

Mobile testing is inevitable nowadays. Mobile apps and mobile Internet that continuously gain popularity dictate the terms to support a variety of mobile devices and platforms. Mobile testing allows us to verify how your app performs on different mobile devices to ensure that your customers have a positive experience with your product.

A dedicated team of QA engineers that focuses on desktop apps performance and game testing will raise your app quality as high as possible. We test games of different genres that run on differnet game consoles and platforms (XBox, Playstation, Nintendo Wii and PC platforms).

Our QA team tests applications of various complexity, including simple web applications (sites, e-shops, SPA-applications, web services, etc.), complex web applications (Internet portals, social networks, online auctions, trading platforms, etc.) and high complexity apps (SaaS solutions, various innovative products, search systems, brokerage trading systems, payment systems, etc.).


Seo testing will show whether your website fully conforms with website optimization criteria (internal and external optimization factors considered). After testing we’ll come up with a list of necessary amendments to the site to drive maximum organic traffic.

Usability testing helps reveal the weak sides of the existing project and the problems with its usability. It also determines user satisfaction with your product and increases the chances of converting your clients into customers. Our QA team will make your app more user-friendly and help you improve your brand image.

This type of testing includes language testing of an app and its localization for specific target markets by adding special locale components and translating text into the required language (localization or internationalization testing).

Exploratory testing allows us to find out how the software actually works by creating test cases. This type of testing is widely used when your requiements and specs are incomplete or you don’t have any documentation at all.
