<h4 class="subsubsection">7.2.6.7 Clean up generated test files</h4>
|
||
|
|
|
||
|
|
<p>Usually the test-framework removes files that were generated during
|
||
|
|
testing. If a testcase, for example, uses any dumping mechanism to
|
||
|
|
inspect a passes dump file, the testsuite recognized the dump option
|
||
|
|
passed to the tool and schedules a final cleanup to remove these files.
|
||
|
|
</p>
|
||
|
|
<p>There are, however, following additional cleanup directives that can be
|
||
|
|
used to annotate a testcase "manually".

||
|
|
</p><dl compact="compact">

Cleaning up module files is usually done automatically by the testsuite

|
by looking at the source files and removing the modules after the test

has been executed.
