Differnce Between System Testing and Integration Testing

Testing service providers use various testing techniques and methods for checking the quality of software products. The choice of testing approach depends on a particular software application under test, the customer’s requirements, project deadlines and other factors.

Thus, there are many types of software testing. It is sometimes difficult to get a detailed understanding of a particular testing type.

Well-trained personnel of a software qa company is the key to the success of your business. It means that the specialists have excellent testing skills and experience to perform any testing in the most efficient way.

Typically, beginner testers have some difficulties in running system testing and integration testing. To understand the fundamental difference between these types of testing, let us learn more about each.

System testing and integration testing. What’s the difference?

System Testing

• It is the process through which the product is tested as a whole (not a module) so that to verify the behavior of the whole system and detect defects in it. At that, the product under test must properly perform its functions, namely in accordance with the customer requirements.
• When carrying out system testing, the tester evaluates whether the system is in compliance with functional and non-functional requirements.
• System testing does not deal with verification of the code and its visual component. Integration testing helps to know how the multiple software modules work together.  
• System testing is the black box testing technique, while combination of white box test design technique with black box test design technique is used for integration testing.

Integration Testing

• It is concerned it helps to verify the performance, functional and reliability of integrated systems or components by using test drivers or test stubs.
• Continuous integration services are delivered to test isolated changes without any delay and report on them once they are entered into a larger code base. The goal is to provide a quick feedback in order that the defects, if they are introduced in the code base, can be detected and fixed as soon as possible.
• Integration testing is run to check how integrated units or systems interact so that to reveal defects in this interaction or in the interfaces. 
• This kind of testing is performed prior to system or unit testing.
