<H3>BOOST_WARN( predicate )</H3>
|
|
<P class="first-line-indented">This tool is used to perform a weak validation
|
|
of the predicate. This check failure does not cause the test case to fail,
|
|
but only warning message logged in test output stream. Use this tool to
|
|
validate aspects less important then correctness: performance, portability,
|
|
usability etc.</P>
|
|
<P class="first-line-indented">If predicate evaluates to <I>true</I>, the tool produces a confirmation
|
|
message (note: to manage what messages appear in the test output stream set the proper log level),
|
|
in other case it produces a warning message in a form "warning in <test case name>: condition
|
|
<predicate> is not satisfied"</P>
|
|
<H4>Example: test.cpp</H4>

<PRE class="code"><SPAN class="cpp-type">int</SPAN> test_main( <SPAN class="cpp-type">int</SPAN>, <SPAN class="cpp-type">char</SPAN>* [] ) {
