Why Do You Need Functional Testing Services?

Thorough Software Functionality Check

By catching the majority of defects before release, functional testing guarantees your software works as intended.

Early Bug Detection

Functional testing helps identify and resolve defects early on, reducing bug-fixing costs, improving product quality, and streamlining the development process.

Fewer Post-Release Defects

Effective functional testing reduces post-release defects by up to 90%, saving a lot of time and resources.

Higher Customer Satisfaction

Comprehensive functional testing improves software quality, leading to higher customer satisfaction.

Functional Testing Services We Provide

Based on the specific needs of your project, we come up with different types of functional testing, executing them manually or with the help of automation. Our scope of functional testing services includes the following:

Regression Testing

Our aim is to confirm that recent updates or code modifications haven't caused any defects in software functionalities that previously worked well.

Smoke Testing

Before getting to comprehensive testing, we check the core app functionalities for critical issues to prevent the wastage of valuable time and resources.

Sanity Testing

We execute this brief and focused testing to check whether a particular set of functionalities or software components work as expected after a code change or a minor update.

Integration Testing

We pinpoint issues that may arise when different software components are integrated, ensuring seamless data flow and interaction.

System Testing

We comprehensively assess software as a whole, checking adherence to predefined functional specifications.

User Acceptance Testing

We work closely with stakeholders to ensure that the software meets specified criteria and is ready for launch.

Read Story

Dev capacity:



Didn’t have a formal QA process

Built smooth and well-working processes

Didn’t make automated testing

Test automation : smoke, API, UI on all supported browsers

Testing was carried out by the devs

Full coverage of the application by test cases

Read Story

Test coverage :



Existing workflow in Jira didn’t allow to understand how many bugs were left unfixed before the release and their priorities

Adjusted the Jira workflow, integrated TestRail with Jira to be able to see statisticls of the issues per release

The lack of test documentation

Developed necessary test artifacts that adhere to industry standards and are easily maintainable

No Automation test coverage

Added multithreading to run tests in parallel on 10 different threads, which reduced the time of the test run in 7 times
