On the basic idea a test is the combination of steps

grouped by test cases. Whether you can run the test (steps)

manualy/automated by adding in test lab.

In Business prosess testing the combination of components

wil become a test(business process test) Components are

easily-maintained, reusable units that perform a

specifictask. They are the building blocks of business

process tests. Each componentis comprised of several

application steps that are logically performedtogether in a

specific order. For example, in a Web application, a

logincomponent might be comprised of four steps. Its first

step could be to openthe application. Its second step could

be to enter a user name. Its third stepcould be to enter a

password, and its last step could be to click the

Submitbutton on the Web page. By creating and calling

functions stored infunction libraries, you can enhance the

component with additional logic to

test important details of the login task.By design, each

component tests a specific part of an application. When

combined, components are incorporated into a business

process test in a serial flow representing the main tasks

performed within a particular business process. The task of

creating and running components and business process tests

is generally performed by Subject Matter Experts working in

Quality Center.
