When people build a product or software, they build it to implement and perform myriads jobs at a time. Functional Testing is, as a result, the all-inclusive procedure by which you determine whether the precise software application performs tasks well or not, for which it was launched or designed. More colloquially, it asks whether the specific software application particularly meets the criteria or requirements. This type of testing is thus what we might rationally think of as the fundamental kind of software testing.
Such testing is done to validate all the functionality of the product. As the name proposes, a functional test is a type of black-box testing that is performed for scrutinizing the functionality of the system or an application or is functioning as expected. It critically involves black box testing and it is not concerned about the app’s source code. Every single system’s function is perfectly tested by giving suitable input, verifying the output and comparing the definite results with the projected results.
This testing encompasses checking of Database, User Interface, security, APIs, client/ server apps and Application functionality under Test. Such testing can be done either using manual or automation. Functional tests are all-inclusive procedure perfectly designed to confirm that all of the components of a piece of code or software function properly. It mainly focuses on testing the interface of the application to guarantee that all user requirements for properly working are met.

In Functional Testing following things are mainly covered:
- Unit Testing
- System Testing
- Integration Testing
- Interface Testing
- Smoke testing
- Regression Testing
- Sanity testing
5 Essential Factors for Successful Functional Test Automation:
1. Build an adept and fervent team
It would be dreadful to get the manual testing team to work on test automation stringent jobs. The strategy and methods for both are different, and even the end results projected would differ. Test Automation is a focused and dedicated activity to consider, and cannot be mixed. For this reason, it is most important to bring a devoted and fervent team on board for the same.
2. Choose a suitable Test Automation Tools
There are some common points to consider while selecting the best functional test automation tools for proper testing — the underlying objective and the training implicated. It is vital to pick out the most appropriate and active tools that are compatible with the company and the people who would be involved in the testing procedure.
Besides, a test automation framework encompasses a predefined set of guidelines and instructions that guarantee the constancy of the functional testing process, improve reusability, and decrease the necessity to conduct constant code maintenance. Experts have defined several critical factors that define the effectiveness of the test automation framework. As a result, an automation framework should:
- Reliable and consistent
- Easy to maintain
- Allow maximizing test coverage
- Be scalable for new needs
- Generate reports of test results
3. Keep the objective in focus for favored results
Again, it is most important and smart decision to keep the objective in focus while constructing the strategy for functional test automation. It is sensible and praiseworthy to start or commence the functional automation testing process by creating the test case in a manual format — gather all the requirements and testing data to build the automation strategy.
4. Understanding and knowing your software or app
Knowing your software or application is also one of the critical steps to consider, understanding the application at one hand and knowing the significant features of the application on the other hand. It will help implement the tool competently and enable right third-party integrations. It will guarantee efficient automation even in the upcoming days. Additionally, it will help identify performance issues, scalability problem, recognize memory leaks, any possible flaws, and more.
5. Automation can’t answer for all
Automation can solve the main critical complications; however, it cannot be done for everything. Therefore, it is a misconception that if you choose a suitable tool you can automate everything. Such automation tools can just make the process fast and simpler. You will have to loop in and make use of the right processes that can meet the preferred objectives.
Functional testing is the practice of testing functionalities of the system and makes sure that the system is working as per the functionalities specified. The main aim of this functional test automation is to verify whether the system is functionally wonderful.
