Manual Testing : Test Suit and Test Script

Test suite :
            In software development, a test suite, less commonly known as a validation suite, is a collection of test cases that are intended to be used to test a software program to show that it has some specified set of behaviours. A test suite often 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, a test script, or even a test scenario.
                   An executable test suite is a test suite that can be executed by a program. This usually means that a test harness, which is integrated with the suite, exists. The test suite and the test harness together can work on a sufficiently detailed level to correctly communicate with the system under test (SUT).
Test Script :
              A test script in software testing is a set of instructions that will be performed on the system under test to test that the system functions as expected.
There are various means for executing test scripts.
-Manual testing. These are more commonly called test cases.
-Automated testing
