type of testing...

Functional testing: answers the question "what "the system does. Functional testing checks the output obtained by entering any input when the output result should adjust our expectations.
 Several types of test:
*Security testing
*Interoperability testing
*smoke test

*Unit/component testing: white box testing. the testing performed by developers. the testing focus in an individual component of the system.

*Integration testing: white box testing. the testing performed by developers. Performed on the system with the center mark on connecting sections of code. the test start from bottom up  and after that go from the top down.

 *System testing: black box testing. ensuring the interactions between systems behave as expected. performed then the development of system ended.

 *regression testing: After changes are made to the code necessary to testing again. the test will be performed to check whether the bugs have been fixed as well really test whether correction of bugs did not lead to new bugs.

Non-functional testing:  answer the question "how" the system do this.
Several types of test:
*Performance testing:
*Load testing: This test checks the load on the system. What amount of users the system can stand without a crash.
*stress testing: Putting the system under stress
*Usability testing
*Resilience testing
*Security testing
*Scalability testing
