SYSTEM INTEGRATION TESTING:-
*It tests the interactions between different systems and may be done after system testing.
*It verifies the proper execution of software components and proper interfacing between components within the solution.
*The objective of SIT Testing is to validate that all software module dependencies are functionally correct and that data integrity is maintained between separate modules for the entire solution.

A testing process that exercises a software system's coexistence with others by taking multiple integrated systems that have passed system testing as input and tests their required interactions?
Integration Testing, abbreviated I&T. Is the phase of software testing in which individual software modules or individual applications, client and server applications on a network, combined and tested as a group. Integration testing is done after Unit testing is completed and before system testing starts. Integration testing takes modules that have been unit tested as its input, groups them in larger aggregates, applies tests defined in an integration test plan to those aggregates, and delivers as its output the integrated system ready for system testing. Different types of integration testing are big bang, top-down, and bottom-up.
What is exact difference between integration and system testing?
After units have been tested, the system must be put together. This involves units starting to work with other units. This is integration. We then need to test how the individual units work with each other, which is integration testing. Just because individual units work properly, that does not mean they will still do so when we connect them with other units. That is why we need integration testing. When all the system has been integrated, we now have a full system. All the individual integrations will have worked, but again that does not mean the whole system will work. At this point we need to do system testing. So in short integration testing is checking how individual units work with other units the communicate with and system testing is testing an entire system.After units have been tested, the system must be put together.

What are the advantages and disadvantages of top down and bottom up testing?
Integration testing is a typically incremental process which involves testing whether individual modules within a system interact correctly.Top-down Integration TestingTop-down integration testing involves starting at the top of a system hierarchy at the user interface and using stubs to test from the top down until the entire system has been implemented. There is no need for test drivers as the user interface provides the means to enter test data. Using Top-down integration testing means that there is a visible system with a certain level of functionality early on.Bottom-up Integration TestingBottom-up integration testing is the opposite of Top-down integration testing. Sub-systems are initially formed at the bottom of the system hierarchy. These are then tested and added to the modules above them to form larger sub-systems which are then tested. Bottom-up integration testing requires the heavy use of drivers instead of stubs.
What comes after unit testing?
These are the next testing levels after unit testing: 1 Integration testing 2 Component interface testing 3 System testing 4 Operational Acceptance testing
What is the normal order of activities in which software testing is organized?
unit ,integration, validation then system
Prerequisites of Regression testing and system testing?
system testing is a kind of retesting where we can test whole system after integration. while regression testing is a process where we do the rerunning the test cases and check whether that re run doesnot affects the real environment.
What is a system integrator?
System integration test is aimed at testing how compatible a system is with an application. This will analyze the system requirements in the computer before installation.
What is the difference between integration testing and system testing In terms of system testing when the test cases for blackbox testing can be designed and when the test cases for whitebox testing?
Integration testing - Its like increment Testing, where we test individual components and their effect on other components as and when they are added. System Testing - System is tested as a whole. You may say that it is integration testing when last component is added. White box test cases are mainly designed and executed by developers or a separate white box test team. This can happen in detail design/coding phase generally during. Blackbox test cases are written once requirements are freezed by test team in parallel to design phase as per V model.
What is the normal order of activities in which traditional software testing is organized?
unit ,integration, validation then system
What is the importance of system testing and documentation in systems?
System testing is necessary because many of the criteria for test selection at unit and integration testing result in the production of a set of test cases which are unrepresentative of the operating conditions in the live environment.
How can project Scheduling affect integration testing?
Scheduling is the approximate time frame definition for future events. Scheduling, for example, is used in laying out the main Framework activities for the project. If the project is behind schedule, then integration testing can't even begin. Integration testing happens after unit testing which happens after coding. Additionally, if scheduling is tight, then project managers could potentially reduce the time in integration testing thus reducing the quality or increasing the cost.
