Question

I am trying to add my first unit test to an existing Open Source project. Specifically, I added a new class, called audio_manager:

src/audio/audio_manager.h
src/audio/audio_manager.cc

I created a src/test directory structure that mirrors the structure of the implementation files, and wrote my googletest unit tests:

src/test/audio/audio_manager.cc

Now, I am trying to set up my Makefile.am to compile and run the unit test:

src/test/audio/Makefile.am

I copied Makefile.am from:

src/audio/Makefile.am

Does anyone have a simple recipe for me, or is it to the cryptic automake documentation for me? 🙂

Answer 1

William’s answer got me where I needed to go. Just for the sake of the community, here’s what I ended up doing:

1. I moved my tests back into the main directory structure and prepended test_, as per William’s suggestions.

2. I added a few lines to src/audio/Makefile.am to enable unit tests:

   # Unit tests
   noinst_PROGRAMS = test_audio_manager
   
   test_audio_manager_SOURCES  = $(libadonthell_audio_la_SOURCES) test_audio_manager.cc
   test_audio_manager_CXXFLAGS = $(libadonthell_audio_la_CXXFLAGS)
   test_audio_manager_LDADD    = $(libadonthell_audio_la_LIBADD) -lgtest
   
   TESTS = test_audio_manager
   

3. Now, running “make check” fires the unit tests!
