# Unit Testing 

 NFD requires unit testing for most modules. 

 NFD uses [Boost Unit Test Framework](http://www.boost.org/doc/libs/1_48_0/libs/test/doc/html/index.html). 

 ## Learning Resources for Boost Unit Test Framework 

 * [Boost Unit Test Framework documentation](http://www.boost.org/doc/libs/1_48_0/libs/test/doc/html/index.html) 
 * After compiling the unit-test binary, it is possible at run time to select which tests to run and what kind of output is desired. 
   Use `--help` command line option to get more information about the available options. 

 ## Testing Code Guidelines 

 * Test suites should be defined inside `nfd::tests` namespace. 
 * Test suites should use `nfd::tests::BaseFixture` fixture, to get automatic setup and teardown of global `io_service`. 
 * If a custom fixture is defined for test case or test case, that custom fixture should derive from `BaseFixture`. 

 ## Testing Helpers 

 * `tests/core/limited-io.hpp` provides operation count and time limit 
 * `tests/daemon/face/dummy-face.hpp` `tests/face/dummy-face.hpp` provides a `Face` that doesn't depend on a socket 
 * `tests/daemon/fw/strategy-tester.hpp` `tests/fw/strategy-tester.hpp` provides a facade to test a forwarding strategy
