What is the difference between validation testing and system testing?
Validation testing is to test software if it meets its stated requirements. System testing is the testing of Software and Hardware together and to find out they both can work together to be successful application.
What is the preferred order for performing testing on information technology project?
1. unit testing,integration testing, system testing, user acceptance testing. 2. unit testing, system testing , integration testing,user acceptance testing. 3. unit testing, system testing , user acceptance testing,integration testing. 4. unit testing, ,integration testing, user acceptance testing,system testing.
Which of the testing technique immediatle follow the unit testing?
sub system testing
What is the Difference between functional and functionality testing?
System testing has classifications like functional and non functional testing. Hence the functional testing is a part of system testing. System testing allows the testers to test the typical end product. Every single module, interface and every minute detail are needed to be tested in system testing. Functional testing is aimed at testing the functionalities of the product being tested. These functionalities include volume, stress, load, security, scalability, performance etc. Hardware and software is not concerned with functional testing. Functional testing involves testing of functional requirements as per the specification. On the other hand, system testing involves testing the system as a whole. This may involve testing of proper installation and uninstalling of the application. System testing tests for all internal and external components that make the system.
Which testing is done to validate the entire product?
system testing
What is system testing in manual testing?
System testing is the type of testing to check the behavior of a complete and fully integrated software product based on the software requirements specification (SRS) document. Its a series of different tests whose sole purpose is to exercise the full computer based system. In SDLC, System Testing is perform as the first level of testing where the system is tested as a whole. In System Testing, we test the both Functional as well as Non Functional parameters of Software Testing. System testing involves testing of following: Testing the fully integrated applications including external peripherals in order to check how components interact with one another and with the system as a whole. This is also called End to End testing scenario. Verify thorough testing of every input in the application to check for desired outputs. Testing of the user's experience with the application. . That is a very basic description of what is involved in system testing. You need to build detailed test cases and test suites that test each aspect of the application as seen from the outside without looking at the actual source code. Every software testing company consider all these things while performing system testing.
Why is top-down testing not an effective strategy for testing object oriented system?
Each object should be responsible for its own logic and data, and so each object's tests should be responsible for its own tests. The top-down approach is the polar opposite of this design, as the top level object would be responsible for testing all of its enclosed objects. This works well in procedural programming, but explicitly violates the concepts of object oriented programming, which states that no object should be concerned about the details of any other object's internal design.

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 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
How module testing is different from system testing?
Module testing - (or unit testing) is testing a single module. Its just testing the tyre of a car. If all screws are tight, air pressure is fine. System Testing - System is tested as a whole. You may say that it is integration testing when last component is added. Just like if all tyres and everything else is attached in car, and then we test it. We test if all together is working fine or not.
What is component testing in software testing?
Testing a specific part of a system or even a program. That would be called a component. So it is component testing.
