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.

Frequently Asked Questions

faq

FAQ

While identifying bugs is crucial, functional testing goes beyond a mere "bug hunt." It's an investment in the user experience. Functional testing fosters trust and confidence in your product, which leads to a higher user acquisition rate and better user loyalty. Moreover, it mitigates potential risks associated with post-release issues, safeguarding your brand reputation and helping avoid potentially costly fixes down the line.

Functional testing acts as a bridge between software development and user engagement. By providing early feedback on usability and functionality, it helps shape the development process toward a user-centric approach. This synergy leads to a more efficient development cycle, reducing the need for extensive rework and revisions later on. Additionally, functional testing fosters a culture of quality within your development team, encouraging proactive problem-solving and continuous improvement.

Nowadays, the market offers a wide range of solutions for automating functional testing. The most popular among them are Cypress, Playwright, Selenium, Cucumber, and others.

While bug count is an important indicator, it's vital to adopt a holistic approach to measuring the success of your functional testing efforts. Consider factors like increased user satisfaction, reduced post-release support tickets, and improved user retention rates. Additionally, track metrics like test case coverage and regression testing effectiveness to gauge the overall efficiency and effectiveness of your testing process.
