Today, in this article I will share the two core types of testing (Functional Testing and End-To-End Testing), if you are in the software industry then you must be aware of software testing.

Software testing is very important part of software development life cycle. Software testing ensures that software is working as expected and does not contain any kind of bug or error in it.

Functional Testing and End-To-End Testing are the most important types of testing, they both have their own purposes and they both perform different kind of testing.

What is a Functional Testing?

Functional testing is a type of testing which is responsible to verify the software all functional requirements. It mainly focusses on testing the individual feature or module of the application software.

These includes the user input validations, proper data processing and the final result generation of the software.

It can be done either manually or using the automated software testing tools.

End-To-End Testing

On the other hand, End-To-End Testing is the type of testing which is responsible to test the entire software application from start to finish.

It also verifies all the components of the software and make sure that these all working together without any error and producing the result which is mentioned in the user’s or client’s requirement.

It also includes the user interface testing, integration of software with other component or other software such as API testing, and check the entire data flow of the software.

Conclusion

Both types of testing have their own benefits and both helps to improve the system by detecting any bug in the software.

If I conclude them, I can say that functional testing mainly focusses on the verification of individual function behavior while end-to-end testing focuses on the entire software which should be working correctly.

I hope this tutorial will help you get some idea about software testing and why are they important to implement during software development.
