Set of test cases is a test suite

In software engineering, a test suite (more formally known 
as a validation suite) is a collection of test cases that 
are intended to be used as input to a software program to 
show that it has some specified set of behaviors (i.e., the 
behaviors listed in its specification).

A test suite often also contains detailed instructions or 
goals for each collection of test cases and information on 
the system configuration to be used during testing. A group 
of test cases may also contain prerequisite states or 
steps, and descriptions of the following tests.

Collections of test cases are sometimes incorrectly termed 
a test plan. They may also be called a test script, or even 
a test scenario.

An executable test suite is a test suite that is ready to 
be executed. This usually means that there exists a test 
harness that is integrated with the suite and such that the 
test suite and the test harness together can work on a 
sufficiently detailed level to correctly communicate with 
the system under test (SUT).

A test suite for a primality testing subroutine might 
consist of a list of numbers and their primality (prime or 
composite), along with a testing subroutine. The testing 
subroutine would supply each number in the list to the 
primality tester, and verify that the result of each test 
is correct.

The counterpart of an executable test suite is an abstract 
test suite. However, often terms test suites and test plans 
are used, roughly with the same meaning as executable and 
abstract test suites, respectively.

test suit in simple words means collection of test
cases.....it is the responsible of test engineer.......

Test Suite is nothing but record of total Test Cases and 
Out of that How much get executed and How much get failed 
and How much test cases get passed this all record we will 
maintain in test suit.

If I m wrong Please correct me.
