25 Functional Testing Types – Examples, Tips & More. Functional testing reviews each aspect of a piece of a software to make sure it works (aka functions) correctly. Quite simply, functional testing looks at what software is supposed to do and makes sure it actually does that. Sep 13, 2012 What is Exploratory Testing? Exploratory testing definition “Exploratory Testing is a testing approach that allows you to apply your ability and skill as a tester in a powerful way.”Testers have to understand the application first by exploring the application and based on this understand they should come up with the test scenarios.
Manual testing is a testing process that is carried out manually in order to find defects without the usage of tools or automation scripting.
A test plan document is prepared that acts as a guide to the testing process in order to have the complete test coverage.
Following are the testing techniques that are performed manually during the test life cycle:
Acceptance Testing
White Box Testing
Black Box Testing
Unit Testing
System Testing
Integration Testing
FUNCTIONAL TESTING is a type of software testing which verifies that each function of the software application, operates in conformance with the functional requirements. Each and every functionality of the system is tested by providing appropriate input, verifying the output, and comparing the actual results with the expected results.
This testing mainly involves black box testing and it is not concerned about the source code of the application.
This testing involves checking of User Interface, APIs, Database, security, client/ server applications and functionality of the Application Under Test. Win 10 update download. The testing can be done either manually or using automation
The prime objective of Functional testing is checking the functionalities of the software system. It mainly concentrates on -

In order to functionally test an application, the following steps must be observed.
| Functional Testing | Non-Functional Testing |
|---|---|
| Functional testing is performed using the functional specification provided by the client and verifies the system against the functional requirements. | Non-Functional testing checks the Performance, reliability, scalability and other non-functional aspects of the software system. |
| Functional testing is executed first | Non-functional testing should be performed after functional testing |
| Manual Testing or automation tools can be used for functional testing | Using tools will be effective for this testing |
| Business requirements are the inputs to functional testing | Performance parameters like speed, scalability are inputs to non-functional testing. |
| Functional testing describes what the product does | Nonfunctional testing describes how good the product works |
| Easy to do Manual Testing | Tough to do Manual Testing |
Examples of Functional testing are
| Examples of Non-functional testing are
|
There are several tools available in the market to perform functional testing. They are explained as follows:
Conclusion:
In Software Testing, Functional testing is a process of testing functionalities of the system and ensures that the system is working as per the functionalities specified in the business document. The goal of this testing is to check whether the system is functionally perfect!!!
