Software testing executes an application to identify whether the actual results match the expected results or not. It helps to assure that the software system is free of Bugs. It can be either done manually or using automation testing services as per the requirements as well as budget. Software testing classified into two categories –
Functional Testing analyze every aspect of the software to ensure that it works correctly. Functional testing checks that system must perform as expected when its features exercised by some other system or straight by a user.
Common Functional Tests –
Benefits of Functional Testing
How Functional Testing Works?
When consulting functional testing services, the team follows a process that looks something like this –
After this method is followed, if the actual results and the expected results match, then it can be concluded that the software work correctly. If they do not match, then an issue is present with the software.
Functional Testing Best Tools
In the era of automation, applications are developed to perform work quickly and efficiently. There are several tools present for testing. From open source to paid versions of tools are available for the use. Various types of Functional Testing Tools are –
Wrapping Up
Creating a highly-scalable and cost-effective software application helps companies to Increase business efficiency. And to build application testing is quite crucial, earlier manual software testing was the most popular approach but now people invest in Automation testing. It is costly but saves a lot of money, time & other resources. Functional testing can be performed both manually and automation depending on the budget & software requirements.

Functional Testing analyze every aspect of the software to ensure that it works correctly. Functional testing checks that system must perform as expected when its features exercised by some other system or straight by a user.
Common Functional Tests –
- Unit Testing – Unit testing must begin at the very beginning to make sure that each block of code performs its intended manipulation of inputs into desired outputs for the next module. Tests an individual unit to validate that each unit of the software performs as required.
- Integration Testing – Takes several individual units of the software and tests them as a group to see that the unit modules connect as desired and convey data throughout the system per the specifications built.
- Smoke Testing – Smoke tests checks the major/critical functionalities of software in a non- comprehensive way to ensure the software works perfectly to move on to additional tests. Execute before the detailed functional tests performed on the software build.
- Sanity Testing – After receiving a software build make sure that minute changes and fixes applied do not have unexpected side effects in, apparently, separate parts of the system. If sanity tests fail, the build will be rejected for cost & time saving.
- Regression Testing – It checks that the features added at the later stages and bug fixes not adversely affect existing features. It is nothing but the selection of already executed test cases which are executed again to ensure existing functionalities work appropriately.
Benefits of Functional Testing
- It makes sure that the customer is satisfied.
- It builds a defect-free product.
- Make sure all the requirements are met.
- It makes sure the proper working of all the functionalities of an application.
- It verifies that the software/product works as desired.
- It guarantees security and safety.
- It enhances the product quality.
- The risks and loss associated are reduced.
How Functional Testing Works?
When consulting functional testing services, the team follows a process that looks something like this –
- Employ test data to find the inputs.
- Find the expected outcome depending on those inputs.
- Run test cases with the support of proper inputs.
- Verify actual results with expected results.
After this method is followed, if the actual results and the expected results match, then it can be concluded that the software work correctly. If they do not match, then an issue is present with the software.
