Thread: what is the difference between SIT & Sytem testing?

What is the difference between sytem integration testing and system testing? and also can u tell what are all the tests that we do under system testing?

Sytems integration testing mainly deals with testing how integration of various modules work. You check if very module is working as per its spec after integration. You also check that functionality that require modules to interact with each other.

Unser Sytem testing you will do, fucntionality test, load/stress test, performance test, compatibility test etc

System testing

1. System testing should be performed as per SRS and FRS
2. In system testing it doesn’t have the knowledge of logic or code. It falls under black box testing
3. All the software components which have been passed integration testing and it is checked with different hardware

System integration testing
1. It requires multiple integrated system that have passed system testing

Hi All,

Here you go with some more points on difference between System testing and SIT

"System testing" is a high level testing, and "integration testing" is a lower level testing. Integration testing is completed first, not the system testing. In other words, upon completion of integration testing, system testing is started, and not vice versa.

For integration testing, test cases are developed with the express purpose of exercising the interfaces between the components. For system testing, the complete system is configured in a controlled environment, and test cases are developed to simulate real life scenarios that occur in a simulated real life test environment.

The purpose of integration testing is to ensure distinct components of the application still work in accordance to customer requirements. The purpose of system testing is to validate an application's accuracy and completeness in performing the functions as designed, and to test all functions of the system that are required in real life.

For some projects integration testing can further be divided into two levels:
– Assembly Integration Testing.
– System Integration Testing.
During assembly testing, the integration of the software components is tested. During system integration testing, the communication with external systems is tested. Integration Test Plan should be written from LOw Level design document

System Testing is Highlevel design and it complaince with respect to SRS.

Hi ,

Types of system testing

The following examples are different types of testing that should be considered during System testing:

• GUI software testing
• Usability testing
• Performance testing
• Compatibility testing
• Error handling testing
• Load testing
• Volume testing
• Stress testing
• User help testing
• Security testing
• Scalability testing
• Capacity testing
• Sanity testing
• Smoke testing
• Exploratory testing
• Ad hoc testing
• Regression testing
• Reliability testing
• Recovery testing
• Installation testing
• Maintenance testing
• Accessibility testing


Each of these testing has detailed Explanation and it would be relevant practiced depending on the Software organisation
