<p>I found something that might be useful from <a href="http://www.boost.org/doc/libs/1_57_0/libs/test/doc/html/utf/user-guide/runtime-config/reference.html#utf.user-guide.runtime-config.parameters">Boost UTF Runtime Parameters</a>.</p>

<p>After setting the parameter <em>log_level=test_suite</em>, Boost UTF print the currently running test information.</p>

<pre><code>Running 460 test cases...
Entering test suite "MLPACKTest"
Entering test suite "AdaBoostTest"
Entering test case "HammingLossBoundIris"
Leaving test case "HammingLossBoundIris"; testing time: 823709mks
Entering test case "WeakLearnerErrorIris"
Leaving test case "WeakLearnerErrorIris"; testing time: 840446mks
</code></pre>

<p>However, the Log:: objects still output to stdout, interfering UTF output. Logs objects probably should redirect their output to some places.</p>

<pre><code>Entering test case "DiscreteDistributionRandomTest" 
[DEBUG]    1.4912e+04   3.0118e+04   4.9700e+03
Leaving test case "DiscreteDistributionRandomTest"; testing time: 17148mks
Entering test case "TestBooleanOption"
[DEBUG] Compiled with debugging symbols.
Leaving test case "TestBooleanOption"; testing time: 410mks
</code></pre>

<p>I want to tackle this problem, but I don't familiar with the framework of mlpack and tools it used(CMake, Boost UTF). Would you like to offer me a help?</p>
