"catkin run_tests" finding non-installed resource

I have 2 packages, baa and foo. There are 2 .test files in pkg foo. Catkin workspace is configured with catkin config --install, so I expect only installed resource can be accessed from rostest. Files in config are not installed.

However during catkin run_test,

• foo.test, which tries to find the file in config folder under the same foo package, seems to be able to find it.
• baa.test, which tries to find the file in config folder under baa package, can't find it.

This result is unintuitive to me; I'd expect in neither case the file should be found. Am I wrong?

$ tree -L 3
.
├── baa
│   ├── CMakeLists.txt
│   ├── config
│   │   └── rsc.yaml
│   └── package.xml
└── foo
    ├── a.launch
    ├── CMakeLists.txt

    │   └── rsc.yaml
    ├── package.xml
    └── test
        ├── baa.test
        └── foo.test

The entire sources can be found here.

Full set of commands to reproduce the case:

$ sudo apt-get install python-catkin-tools 
$ DIR_TEST=/tmp/rostest_test
$ mkdir -p $DIR_TEST/src && cd $DIR_TEST/src
$ git clone https://github.com/130s/prooving_grounds.git -b rostest_install_rsc
$ mv prooving_grounds/ros/rostest_runtests/ . && rm -fr prooving_grounds/ && cd ..
$ catkin config --install && catkin run_tests
