CMake verbose output from tests

Question

How do I get "make test" to display verbose output? I want "make test" to do the same thing as ctest -V through the command line.

I have tried adding the following to my CMakeLists.txt, nothing worked :(

set(ENV{CTEST_OUTPUT_ON_FAILURE} TRUE)

add_custom_target(check COMMAND ${CMAKE_CTEST_COMMAND} --verbose)

add_custom_command(TARGET test PRE_BUILD
               COMMAND ${CMAKE_CTEST_COMMAND} -V)

But I still get this when I run make test:

  Start   1: unittest1
  1/143 Test   #1: unittest1 ....................................   Passed    0.01 sec
        Start   2: unittest2
  2/143 Test   #2: unittest2 ............................   Passed    0.03 sec
        Start   3: unittest3
  3/143 Test   #3: unittest3 ....................   Passed    0.02 sec

To clarify, I want to add something to my CMakeLists.txt to make this possible, I don't want a manual solution that requires me to append something to "make test" in the command line such as

CTEST_OUTPUT_ON_FAILURE=TRUE make test

or

ctest -V 

_{My question is similar to Using cmake how do I get verbose output from ctest?.}

Answer 1

From GNU Radio's wiki page on doing tests on out-of-tree modules (courtesy of Mr. Braun):

Run ctest -V from the build directory (usually), and it will give you verbose information. Add -R regex to execute only tests that match regex.

Now, re-running a test on failure does seem to make a whole lot of sense to me -- and not automatically doing that on every make test, too, as tests might be time-consuming, and shouldn't be repeated in a broken build environment, etc. by default.

How to add that behaviour to the default make test behaviour of course depends on your CMake infrastructure, and I can't answer that without reading through your code.
