As the title suggests, it is not only about choosing one between Unit testing and Functional testing for software development, the blog will cover much more. As a matter of fact, you will see in the blog that both software testing types have their own importance in offshore software development, and have their own advantages as well as limitations. However, there are different contrary opinions about both the functional testing types. Thus here we have compared Unit Testing Vs Functional Testing.
To put it another way, the ultimate aim of any software testing is to provide a quality product. Another key point of the foundation of the testing process is Unit and Functional testing. Generally speaking, the major difference between the two software testing types is:
- At the time of the development cycle, the developer performs the Unit testing, and
- The tester performs the Functional testing at the level of system testing in software development
With this in mind, you will get to know several such differences through this blog. With this in mind, the blog post aims to make you understand the different aspects of both software testing types. Moreover, this blog post will cover the parameters like the objectives of both types of testing, benefits of each software testing types, differences, and other valuable information. So, stay tuned!
Let’s see the prime objective of Unit testing:
- It tests the units of code in isolation
- It verifies if the code is correct
- It tests each function as well as procedure
- It detects bugs earlier and fixes them in the development of software cycle simultaneously saving cost
- It helps in understanding the code-base by the developers and allows them to quickly make changes
- It also assists in code reuse
- Unit testing enables mobile app developers to know about the functionality provided by a unit. Additionally, explain to you the way of using it for gaining a basic understanding of the unit API
- Unit testing enables the developer to refine code and ensure the working of the module is appropriate
- Unit testing allows testing of the project’s parts without relying on others for the purpose of completion
Functional testing is a process of software testing that substantiates the software system in opposition to functional specifications. Testing every functionality of software application is the purpose of functional testing which is done by providing appropriate input and output verification against the functional specifications. In simple words, functional testing is a type of testing in which the system is tested in opposition to the functional requirements or specifications.
- It detects the defects that might be missed by programmers while developing software
- It helps in gaining confidence and delivers information regarding the level of quality
- It ensures the outcome that meets the business and the user’s expectations
- Functional testing is very essential for the evaluation of performance and the functionality of a software application before delivering it to the client
- Considering the user’s perspective enables the software development team to build test scenarios representing the real-world use scenarios
- Enabling the team to meet all the requirements/demands of the user and client both
- This types testing helps in improving the actual system usage
- The quality of the software product is enhanced with the use of Functional testing
