Different Levels of Testing in Software Development:
There are four levels of Testing in Software Development. Each level has their own Functionality. The Functionality of the four levels of Software Testing is mentioned Below:
- Unit Testing
- Integration Testing
- System Testing
- Acceptance Testing
Unit Testing:
Unit Testing is generally done to check whether the individual module of the source code works properly without any error. It means testing every unit module of an application by the developer in the developer’s environment. It is also known as Component Testing.

Integration Testing:
Integration Testing processes the testing of the connectivity or data transfer between a couple of unit-tested modules. It is also known as AKA I & T Testing or String Testing. It is subdivided into categories such as Top-Down Approach, Bottom-Up Approach, and Sandwich Approach (Generally a Combination of both Top-Down and Bottom-Up Approach).
System Testing:
System Testing is a Black box testing known as End to End Testing. Testing is a fully integrated application which is called end-to-end scenario testing. Ensure that the software works in the intended target systems, must verify thorough testing of every input in the software applications to check for desired outputs.
Acceptance Testing:
Acceptance Testing is also called pre-production testing. It is usually done after the system testing, which is the final phase of the Software Testing process. Generally, companies hand over the application to the desired customer to perform the acceptance tests only if the system testing is entirely over and it’s signed off. To obtain a customer sign-off so that the software should be delivered and payment must be received. Some of the various types of Acceptance testing are Alpha, Beta and Gamma Testing.
