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>

</ul> <p>All APIs that Symbian classify as <b>PublishedAll</b> are tested

within this class. </p> <p> <b>Note:</b> Any mention of <codeph>epoc32</codeph> is

offset by <codeph>%EPOCROOT%</codeph> that is, the full path where the epoc

tree is installed. </p> </section>

<section><title> Test approach</title> <p>The test suite ensures that the

APIs work as expected. Negative testing will be performed where applicable

to confirm that errors are returned as documented. The tests are completely

automated. </p> </section>
