System testing definition

System testing is the testing process in software testing to verify the completeness of system with its original requirement and to find the problems. System testing is start after completing the integration testing. System test is the third phase of testing in STLC. System test is most important phase in STLC because bugs not found in unit and integration testing are founded during system test.

Definition of acceptance testing

Acceptance testing is performed by software testing engineer or end user. Acceptance test gives confidence to end user that application being delivered to them meets their requirement or not. Acceptance testing is fall under black box testing.

Definition of integration testing

Integration testing is the testing process in software testing to verify that when two or more modules are interact and produced result satisfies with its original functional requirement or not. Integration testing is fall in Black box testing. Integration testing will start after completion of unit testing.  Software testing engineer is performing integration testing.

Unit testing is the testing process in software testing to verify that the smallest testable part or a unit of an application, are tested independently and individually to verify that specific unit is working fine as per requirement or not.

Generally software developers have to do Unit testing when they develop smallest part of an application. After development of specific unit of an application, developer check and verify that how behaves new developed unit independently. If there is any error or bug then they have to solve it in first stage.

Types of Testing in Software Testing

Software tester has to do many types of testing in developed software as per the requirement of application and requirement of client/user. But from them, four testing types are main and will be performed on any new developed application or software in software testing. Here is the list of those main four types of testing.

Definition of software testing:

Software testing is a process of validating and verifying that a software application or software program is developed and work as per the business or user requirements.

Why software testing require?

why software testing require is the question in mind of everyone who doesn’t know anything about software/IT field. Now I am describing why sw testing is needed.
