 ## C++ Unit test
+
 C++ code can be tested using [Google Test][]. Most features in Node.js can be
 tested using the methods described previously in this document. But there are
 cases where these might not be enough, for example writing code for Node.js
 that will only be called when Node.js is embedded.
 
 ### Adding a new test

 The unit test should be placed in `test/cctest` and be named with the prefix
 `test` followed by the name of unit being tested. For example, the code below
 would be placed in `test/cctest/test_env.cc`:

 Note that the only sources that should be included in the cctest target are
 actual test or helper source files. There might be a need to include specific
 object files that are compiled by the `node` target and this can be done by
 adding them to the `libraries` section in the cctest target.
 
 The test can be executed by running the `cctest` target:
