 Testing the complete system with respect to requirements.  In System testing, the functionalities of the system are tested from an end-to-end perspective.  If you are a software developer the last test you will do before handling over the system to the user for acceptance testing.

 Testing the unit or element of a software.  Unit tests are basically written and executed by software developers.

 Integrate the unit tested module one by one and test the behavior as a combine unit.  When the developers combine the different tested units and see if there integration point is working correct or not.

 Functional Testing.  Sanity Testing.  Ad hoc Testing.  Performance Testing.  Stress Testing.  Load Testing.  Security Testing.  Usability Testing.  Regression Testing.

 The prime objective of functional testing is checking the functionalities of the software system.  Each and every functionality of the system is tested by providing appropriate input,verifying the output and comparing the actual result with the expected result.

 It is very basic level of testing done by QA by after fixing some “bugs”.  sanity testing is performed to ascertain that bugs has been fixed and no further issues are introduce due to these changes.  A sanity test is a narrow regression test that focused on one or a few areas of functionalities.  Sanity test is usually narrow and deep.

 Testing without any process, procedures, organized approach is called ad hoc testing.  Ad hoc testing is not structured and is a random type of testing.

 Performance testing is a process of determining the speed or effectiveness of a computer, network, software program and device.  Check the response time at which a system functions.  Goal : Is to reduce the response time to an acceptable level.

 Stress testing is use to determine the breaking points or safe usage limits, to determine the modes of failure. (how exactly a system fails)  Aim of this testing is to find at what point system will break.

 Load testing is the process of putting demand on a software system or computing device and measuring it’s response.  Check at what point application performance start to degrade.

 Security testing helps in finding out the loopholes that can be the cause of loss of important information.  We check that the application is secure against the unauthorized access, viruses and other attacks.

 Application is easy to use and understand.

 Regression testing is the process of testing, changes to computer programs to make sure that the older programming still works with the new changes.  When we found a bug in verification and fixed it then we need to verify : 1. Fix is done correctly. 2. Verify that the fix does not break anything else. This is called Regression Testing.

 Acceptance testing is a testing technique performed to determine whether or not the software system met to requirement specifications.  Acceptance testing is a level of the software testing where the system is tested for “Acceptability”.
