<H3>BOOST_CHECK_EQUAL( left, right )</H3>

<P class="first_line_indented">The same as <A href="BOOST_CHECK.html">BOOST_CHECK</A>( <I>left</I> ==
|
|
<I>right</I> ). Use this tool to see mismatched values. Note that it most probably bad idea to use
|
|
this tool to compare floating point values. Use <A href="BOOST_CHECK_CLOSE.html">BOOST_CHECK_CLOSE</A>
|
|
tool instead.</P>
|
|
<P class="first_line_indented"> If comparison is successful, the tool produces a conformation message
|
|
(note: to manage what messages appear in the test output stream set the proper log level) in other
|
|
case it produces an error message in a form "error in <test case name>: test <<I>left</I>
|
|
argument name> == <<I>right</I> argument name> failed [ <<I>left</I> argument value>
|
|
!= <<I>right</I> argument value>]".</P>
|
|
<P class="first_line_indented">The tool's first parameter is the <I>left</I> compared value. Second
|
|
parameter is the <I>right</I> compared value. Parameters are not required to be of the same type.
|
|
But there should exist comparison operator for <I>left</I> and <I>right</I> type (this may involve
|
|
implicit conversions).</P>

<H4>Example: test.cpp</H4>
