Functional Testing Services
Functional Testing Services
Several types of functional testing services are offered by testers that will eradicate the most significant issues from your software. The following are the functional testing services that you can get.

Unit Testing
Performing unit testing will validate the functionality of a specific software component to ensure that they work as anticipated. Executed at the early stages of development, unit testing helps in saving significant costs in defect fixing. Techniques used in testing include boundary value analysis, branch coverage, decision coverage, and statement coverage.

Component Testing
Component testing involves testing various software modules in isolation to identify any underlying issues. Moreover, it is performed on a section of the code after completion. Though it may sound similar to unit testing, the only difference is that it also tests whether the components work together as expected after integrating with other components or not.

System Testing
Also referred to as end-to-end testing, system testing involves testing the software to determine that all the functional and business requirements are fulfilled. System testing can identify any performance, functionality, or compatibility issue, reducing the overall delivery time of the software.

Acceptance Testing
Understand the acceptance rate of your software by the end user. Performed after system testing, this black-box testing technique aims to ensure that your software meets the requirements and needs specified by the end users. This testing ensures that your application is accepted rapidly by the users, increasing your software's initial and overall growth rate.

Regression Testing
Sometimes, code fixes or implementation of new features can hamper the software's existing functionality. Regression testing ensures that any code modification does not introduce new issues to the software.

Smoke Testing
Named after the practice of testing electronic equipment, smoke testing is performed to understand whether the new code is stable enough to test further or not. Only the core and most critical functionalities are considered for testing here.

Sanity Testing
Similar to regression testing, sanity testing involves testing software when adding new code. However, the difference lies in the target areas. Sanity testing targets only the affected areas of the code. The build will not progress to the next phase if it fails sanity testing

Integration Testing
Unit testing ensures that individual components of the software work efficiently. However, they need to work together in a group to complete the software. Integration testing validates that every component communicates and works together to ensure they function appropriately.
Identification of Defects
Functional testing begins at the initial stages of development and is performed until the software is released. This rigorous testing identifies defects and bugs in the software and allows developers to fix them before they become serious.
Better Functioning Software
Functionality testing is all about testing the functions of the software to ensure they work as expected. By ensuring that each feature works as required, it meets the requirements of the end-users.
Minimize Risk
Software failure can impact the organization or users. Addressing issues in early development stages through functional testing can reduce the risk of expensive fixes, downtime, and reputational damage.
Improves User Experience
User acceptance testing in functional testing ensures user satisfaction and usability. It validates software responsiveness, user interface, and error rate. The report informs developers of optimization and enhances user experience.

Frequently Asked Questions
How is functional testing different from other testing types?
In functional testing, the overall functionality of the software such as user interactions, features, input validation, and data manipulation is evaluated. On the other hand, other testing including security or performance is targeted towards data safety and speed of the software.
Is automating the functional testing process possible?
Many organizations prefer automating functional testing processes to increase their speed and efficiency while reducing manual efforts. Automation can be achieved through industry-leading frameworks and tools.
How do you ensure comprehensive test coverage in functional testing?
Before executing the tests, our experts create a well-defined test strategy based on your requirements. This strategy involves test case designing that covers various scenarios such as user workflows, and boundary conditions. Moreover, various techniques and test cases are implemented to ensure comprehensive test coverage.
Can you help in fixing issues found in the testing process?
ThinkSys not only helps in identifying the issues, but fixing them in minimal time consumption. Our team will work closely with the developers to understand the defect’s origin and ensure that the issues are resolved without causing any error to the existing functionality of the software.
When should functional testing be performed in SDLC?
For the best outcome, functional testing should begin early in the software development lifecycle. Doing so helps in early defect detection, and requirement validation, and saves time and resources throughout the process.
