Functional Testing

Functional testing occurs when it is necessary to verify the conformity of the system features to the stated requirements. KeyUA specialists carefully check software and applications both with or without specification.

White box testing
Black box testing
Full checking of basic functionality

System Testing

If you are looking for someone who can conduct high-level testing of all the software, we would be happy to help you with this. Our team will prepare comprehensive test cases and verify compliance with functional and non-functional requirements.

Check unintended application use cases
Environment compatibility checking
Alpha & beta testing

Performance Testing

Do you need to determine how fast the system works, how it behaves under load, or what its maximum throughput is? Our quality assurance experts carry out comprehensive tests to determine the maximum parameters at which the system will work normally, as well as identify the results at which the system stops responding.

Load testing
Stress testing
Cloud channel testing

Regression Testing

Adding new features may cause old features to fail. The purpose of regression testing is to determine how changes in the system affect its functionality as a whole, identifying defects in the new and old functionality.

Full testing of all components
Version testing
Checking of already fixed bugs

Security Testing

Want to check how strong the security of your software is? Our testing services focus on providing a holistic approach to application security, including detection of bottlenecks, malware, and access to private data.

Authentication testing
Internal processes check
Examine the business logic

Usability Testing

You need usability testing when you want to check if the product interface is user-friendly, understandable, and attractive. KeyUA testers will quickly deduct any problems associated with UX and UI.

Quality Assurance Solutions

We direct all efforts to maintain the high quality of the product at all stages of development and even after release.

Manual Testing

KeyUA testing specialists model all types of user behavior in order to identify software vulnerabilities and incorrect functionality. We carefully check how the application works with all operating systems.

Automated Testing

Autotests guarantee the right performance of critical parts of the system. They are created to check important functionality in a short time, accelerating time to market. Our testing experts have an extended pool of tools for automation, with a focus on Selenium.

Unit Testing

Unit testing is performed by developers immediately after writing the code. It means that software engineers create a program that tests their code. It's a good way to quickly identify numerous errors and reduce the testing time of QA specialists.

Code Audit & Refactoring

The code is audited by a developer who did not write the tested functionality in order to determine how the code can be improved from an independent point of view. Refactoring is also equally essential, as it enables software engineers to significantly improve the speed and performance of the system, without changing the basic functionality. KeyUA developers are fully result-oriented and deliver top-notch code even in a short time.

Project Steps

We take a very responsible approach to the testing process to make sure that the product meets the highest quality standards. Our quality assurance process is as follows:

Documentation Analysis

We study the business requirements and project functionality. This step includes working with documentation, as well as cooperating with developers or analysts.

Assessment and Testing Planning

Based on data obtained as a result of the analysis, we develop a testing plan and strategy, including information on which environment the quality control will take place and with what data, the development of basic criteria and standards, etc.

Scripts Development

This step is the creation of all possible scenarios of user behavior in order to find the conditions under which the system starts to work incorrectly.

Testing

We begin to check the app for compliance with the stated requirements.

Summarizing

At the end of testing, we create detailed reports on the gathered results, as well as set tasks for developers if something needs to be fixed.

Examples of Our Successful Projects

At KeyUA we provide services for beginner entrepreneurs, federal agencies, corporate clients, and large businesses. Over the 12 years, we have been delivering quality web apps to the market, most of which we support until now.

Frequently Asked Questions

Below we have prepared a list of the most common questions that customers ask us.

What is the cost of app testing?

The price depends on multiple factors, including the complexity of the functionality and the number of specialists who will work on the software. You can contact our technical experts to get an assessment of your project, including plan, cost, and time.

What do you need to test my application?

In order to start working on your project, we must get a specification with requirements, access to the product, mockups, and source code (if you want us to conduct code auditing, unit testing, or refactoring). You can give us the requirements orally, after which our specialists will prepare the relevant documentation.

Can you fix bugs in my software?

Yes, we can fix any inconsistencies in your mobile or online application, even if we did not write the code. To do this, our team will need to first check your mobile or web application and compile a report. After which, we can sign a contract with you for development, and our engineers will begin to correct the code.
