In software testing, a test harness is a collection of software and test data configured to test a program unit by running it under varying conditions and monitor its behavior and outputs. It has two main parts namely, Test execution engine and the test script repository

Test harnesses should include the following capabilities:

A standard way to specify setup (i.e., creating an artificial runtime environment) and cleanup.

A method for selecting individual tests to run, or all tests.

A means of analyzing output for expected (or unexpected) results.

A standardized form of failure reporting.

Test Beds :

A testbed is a platform for experimentation for large development projects. They allow rigorous testing of scientific theories and new technologies.

The term is used across many disciplines to describe a development environment that is shielded from the hazards of testing in a live or production environment.

Setting up the Hardware and software requirements (Environment) before start testing is known as test Bed

Test Suite : The most common term for a collection of test cases is a test suite. The test suite often also contains more detailed instructions or goals for each collection of test cases. It definitely contains a section where the tester identifies the system configuration 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).

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.
