Quality Assurance Services

Measure twice, cut once. Errors detected in software after the release phase can have devastating consequences not only for the user interaction but also for your budget and success of the app as a whole. That is why any product must be thoroughly tested before it can be used effectively and safely. By following the Quality Assurance approach, we go beyond the surface, find and fix defects, thereby reducing the level of risk and improving the overall software quality.

Quality Assurance Services

We make your idea flawless

Implementation of fully working systems with no hidden pitfalls and flaws is one of our core objectives. We take care of every aspect of the client’s software by testing it far and wide before the official launch. Through the QA sessions, we strive to ensure that a product works stably and is devoid of bugs, errors, and noncompliance at every stage of its life cycle. Our QA services aren’t about eliminating shortcomings. They’re about bringing more value to your IT infrastructure and strengthening your confidence in the delivered technological solution.

Building QA processes in SDLC

Testing is a comprehensive process, not just a phase. When QA is considered only as one of the many phases in the development process, you run the risk of disrupting the deadline and missing some crucial defects. Companies are trying to bring together all types of testing and examine the product in all areas at the final stage. In most cases, they face issues related to product safety, stability, and functionality.

That’s why we set up QA processes on each step of the Software Development Life Cycle. Such an approach allows us to drastically increase the client’s product quality and performance. Instead of overloading QA specialists with tests prior to product release, we plan testing flow in advance. As a result, we detect errors in the early stages, thereby, speeding up and facilitating the fixing process.

Functional testing

To ensure that we’re on the same wave with a client when it comes to product vision, nothing can give us more benefit than functional testing. We use this method to check out that a dev team implemented all features based strictly on your requirements.

To do this, our QA engineers check the ability of an information system to solve the problems of users (user cases) under different conditions. By simulating the actual use of the system, functional testing allows us to quickly identify existing errors and fix them as soon as possible, even at the earliest stages of the software life cycle.

Usability and UI

During Usability testing, we check how easy it’s to use the product and whether it complies with specified requirements by a client. During UI testing our primary task is to ensure that a GUI interface is built in accordance with an approved prototype. Identification of structural and visual mismatch helps us to modify the app interface and ensure its convenience for navigation and understanding by users.

We use several approaches, including manual testing to verify the UI of the app in comparison to the layouts, automated testing after each product build to detect interface errors and regression bugs and use focus groups. All this is accompanied with cross-browser and multiplatform testing.

As a result, you get a high-quality app interface that perfectly matches original mockups and correctly work on all existing devices and in every browser.

Unit testing

Unit testing is a way to separately test the behavior of each independent unit of program code in the artificial environment. By using it, our dev teams test individual units/components and prepare separate parts of the code for testing these units/components. Finally, we clearly understand the role of each class within the entire software system.

The main benefit of unit testing is reducing risk of regression defects after code changes.

Automation of testing

The automated testing is an analog of manual functional testing that comes in our handy when we can’t conduct some tests manually or they require significant expenditures (additional equipment, personnel, etc). Through the use of special automation tools, we prepare end-to-end automation scripts to check whether product features are working correctly. Such an automated approach improves the quality and speed of the testing process.

Performance/Load/Stress testing

We use these types of testing to check out whether your product can work with the required amount of users and under extra loads.

The difference is that load and performance testing measure response time when an application is used by a larger number of users. Thus, we test the potential ability of the application to increase the server load and cause crashes of servers. During the QA session, we ask: “Is the system fast enough?”

Alpha/Beta/Acceptance testing

In case you want to conduct an independent QA assessment of your product, you can request KeplerCode’s acceptance testing service. We apply alpha and beta testing to determine whether the product is ready for mass consumption.

Dedicated QA teams

We can assign dedicated QA teams for your long-term (e.g. executing QA tasks on a full-time basis while SDLC) and short-time (e.g. conducting some targeted complex types of testing) testing initiatives.

Our QA specialists can be both the part of our internal team working on your projects from A to Z locally, and the dedicated team, which expands your in-house departments, being responsible for independent testing of your products.

Even being geographically distributed, we pay special attention to effective communication, competent documentation, skillful use of processes, their continuous improvement and adaptation to changing project conditions.

QA education

We’re happy to share our expertise and insights in the area of software testing by providing a comprehensive range of QA trainings for your engineers. Your team will get advanced knowledge as well as practical skills needed for a more efficient testing workflow within your company.

Generally, we educate in two directions: manual testing and automation of testing. This includes an introduction to the fundamentals of manual testing, explanation of the process essence and assistance in drafting documentation, and applying theoretical skills in practice to implement your own automation testing environment.

Security testing

This test is aimed at diagnosing the potential ways of hacking the system and assessing the security of web, mobile, and desktop projects. We analyze the system risks and check how well the confidential data are stored to determine whether your app can be hacked. Based on the principles of confidentiality, availability, and integrity, security testing helps us ensure the safety of data, accounts, access, and connections of your users.

By assessing the potential vulnerability of system components during security testing, our QA engineers check the actual reaction of the product’s defense mechanisms and form practical recommendations on how to increase the level of security against unauthorized actions. After testing, we apply the standard requirements for the protection of applications and provide a list of defects with gradation on the vulnerabilities’ severity.
