Gtest

Add unit testing to wolf with googletest.

If the BUILD_TESTS option is enable in the top level CMakeLists.txt it will retrieve googletest from github and compiles it.

Then all wolf-tests present in the test folder are compiled in one single executable. This executable can be break-down into smaller chunks - see test/CMakeLists.txt

Provide a very simple test as an example.

To test this PR:

• if you built with catkin build, you can run tests with catkin build -v --make-args test, or to execute them individually :

$ cd ~/my_wolf_ws/build/wolf/bin
$ ./gtest_example

• or if you built with cmake/make:

 $ cd ~/path_to_wolf_root
 $ ctest

or or to execute them individually:

$ cd ~/path_to_wolf_root/bin
$ ./gtest_example

@jsola here you go, I've move tests to the test/CMakeLists.txt

Please try it before merging to be sure everything goes well on another machine than mine.

Moreover if the ctest command still work fine, the catkin run_tests command do not see them anymore. I guess I will worry about it once we merge !81 (closed) .

@jsola any news here ?

Mentioned in issue #59 (closed)

I cannot follow your instructions. Please be precise otherwise it's a lot of time for me to figure out:

jsola@encantats:~/dev/wolf/build$ ctest --VV
Test project /home/jsola/dev/wolf/build
No tests were found!!!

and also

jsola@encantats:~/dev/wolf/build$ ./gtest_example
bash: ./gtest_example: No such file or directory

of course this is not the right folder, but it is not in /bin either.

Sure, I'll update the instructions.

@jsola I have rebased this pr on top of master & updated the commands in the first post of this thread.
Please let me know if you encounter any issue.

Cannot compile because old warnings are now errors. Can you revert the compiler flags to the original situation and make a new MR if necessary with the compiler flags?
