Our Functional Testing Services
  • Unit Testing 

  • Rigorously test individual components, modules, and different code units of the application to achieve the required functionality output. Our QA engineers and developers perform tests and validate each unit or software module against the required parameters. We perform unit testing in both manual and automated ways to fix errors/bugs early in the development cycle at reduced costs.

  • Ensure that not just individual components of the system work perfectly but also work coherently when integrated to achieve the required business results. We perform integration testing under different integration scenarios to validate the functional, performance, and reliability of the system. Our expert QA team carries out both positive and negative integration testing.

  • Integration Testing

  • System Testing

  • Test and evaluate your complete application in aligned with the specified requirements, compliance, and business scenarios. We check the end-to-end workflow, functionalities, and behavior of the system and validate whether it performs as per the end-user expectations. Our system testing services include both functional and non-functional testing.

  • Detect errors, bugs, or defects in the early development stage of your application. Our smoke testing services improve the quality of the application, minimize the risk of failure, and saves test efforts and development time. We perform both manual and automated smoke testing to maintain the system's correctness and ensure its build stability.

  • Smoke Testing

  • Sanity Testing

  • Save time on identifying defects in the core functionality of your system or application. We verify all the significant and vital functionalities of the application so that you can proceed with more stringent testing. We also offer customized sanity testing services like checking only the entire system's specific components or applications. Our goal is to save time for the rollout of regression tests.

  • Re-execute and reverify existing functionalities if your application goes under code-level changes. Our regression testing ensures that your application works according to the specifications when new code is added, bugs are fixed, existing functionalities are enhanced, or new integrations occur. We perform corrective, selective, progressive, and complete regression testing for the desired outcome.

  • Regression Testing

  • UAT Testing

  • Promote your application or system to the production environment with confidence. We expose your system/application under all the acceptance criteria such as functional completeness, usability, performance, and timeliness. We use best practices, advanced tools, and practical techniques to maximize your revenue and enhance your brand reputation.

Our Functional Testing Services Approach

Minds Task technologies adopts industry standard testing tools, techniques, methodologies, test accelerators to eliminate expensive rework via detecting system bottlenecks at early development stages. We focus on determining whether your application is doing what is expected from a business perspective in order to minimize the time between development/testing time and the actual release schedule.

 

How We Deliver Business Results

Our QA specialists and testing engineers help you understand the everyday challenges of testing and how functional testing services can be utilized effectively in improving your applications. We take a holistic approach to comprehend and harmonize with your application strategy, the operating environment, and the organizational structure. We have helped many clients across different industry verticals with our functional testing services to get high-quality systems or applications within the defined time and budget.

FAQ About Functional Testing Services
What is functional testing?

Functional testing is a software testing category that tests and validates the application or software system against the desired functional specifications or requirements. Functional testing assesses each function of the software application by feeding the appropriate and correct input and verifying the output against the desired functional requirements of the business. Referred to as black-box testing, it aids in testing the system's features or functionality. The results of a functional test can normally be stated as a simple “pass” or “fail”. Functional testing can be performed manually or using the automation tools.

Functional testing helps in verifying what the system or application is supposed to do. Functional testing comprises simple methods and steps to execute the test cases. It primarily focuses on mainline functions, basic usability/interfaces, accessibility of the system for the user, and check for error conditions. Moreover, functional testing checks UI elements, APIs, Database, Security, Client/Server interaction, and other components. The testing phase includes the unit, component, and integration systems. However, functional testing requires in-depth customer and system/application knowledge and domain knowledge to develop test cases and find critical defects.

Functional testing has many categories, and these can be used based on the scenario. The most prominent types of functional testing include:

  • Unit Testing– Test individual components, modules, or code units to achieve a particular functionality.
  • Sanity Testing– Ensure that all the major and crucial functionalities of the application/system are performing well.
  • Smoke testing– Performed in order to ensure the build stability of the system.
  • Regression tests– Conducted to ensure that new enhancements are not breaking the existing functionality or causing any instability.
  • Integration tests– Ensure that the system or applications work ideally when linked or integrated with other systems.
  • Usability testing– Performed in the actual kind of environment to provide the real user experience.

There are a plethora of tools available for functional testing. Various tools can be used for both manual testing and automation testing. Some of the most preferred tools for functional testing are:

  • Ranorex
  • Selenium
  • Test IO
  • Telerik
  • CUIT

Selenium is one of the most preferred tools for testing.

We, at Minds Task technologies, recommend the best-of-breed functional testing tools so that you get maximum output and performance for your application or system. If you have any specific questions regarding functional testing tools, feel free to call us.

A software system may be defective due to design/UI issues, database errors, code-level bugs, or other factors. Certain system states are exposed to defects, usability issues, and other functionalities issues, resulting faults/errors in the system's development. Failure in functional accuracy usually results in reduced system reliability, usability, security, and availability. Functional testing is performed in all testing phases, such as unit testing, component testing, integration testing, and system testing. It verifies and validates functionalities and specifications as part of software development. It performs various activities under verification and validation during different SDLC stages to speed up the release cycle at a defined cost.

The principles in testing are essential for successful execution. They form the basis of methods, techniques, methodologies, and tools. They provide better understanding, in-depth evaluation, and higher success rate. Main principles of testing include:

  • Better to fail every time than sometimes
  • Early testing saves time and money
  • Beware of the pesticide paradox
  • Testing is context-dependent
  • Make the problem easier
  • Defects cluster together
  • Apply lessons from experience in process and techniques
