Recommendations
---------------

ndn-atmos code is subject to NFD [code style]
(http://redmine.named-data.net/projects/nfd/wiki/CodeStyle).


Running unit-tests
------------------

To run unit tests, ndn-atmos needs to be configured and build with unit test support:

    ./waf configure --with-tests
    ./waf

The simplest way to run tests, is just to run the compiled binary without any parameters:

    # Run ndn-atmos catalog unit tests
    ./build/catalog/unit-tests

However, [Boost.Test framework](http://www.boost.org/doc/libs/1_48_0/libs/test/doc/html/)
is very flexible and allows a number of run-time customization of what tests should be run.
For example, it is possible to choose to run only a specific test suite, only a specific
test case within a suite, or specific test cases within specific test suites.

By default, Boost.Test framework will produce verbose output only when a test case fails.
If it is desired to see verbose output (result of each test assertion), add `-l all`
option to `./build/catalog/unit-tests` command.  To see test progress, you can use `-l test_suite`
or `-p` to show progress bar.

There are many more command line options available, information about
which can be obtained either from the command line using `--help`
switch, or online on [Boost.Test library](http://www.boost.org/doc/libs/1_48_0/libs/test/doc/html/)
website.
