Framework test suite</title><prolog><metadata><keywords/></metadata></prolog><conbody>
<p>This topic describes the Multimedia Framework test suite. It provides an
overview about the test suite, its coverage, how to set up the test environment
to execute the test suite, and how to find further information about the test
cases offered by this test suite. </p>
<section><title>Test suite overview</title> <p>The Multimedia
Framework test suite consists of several regression test suites that provides
tests for the following classes: </p> <ul>

to confirm that errors are returned as documented. The tests are completely
automated. </p> </section>
