I need to apply a certain validation to my test files, our project uses make, so I'm trying to do that using make, too. The problem I'm running into is that I can either get all the test files in the first level of my dirs, or the second and lower:
TESTS = dir_1/**/test_*.py \
dir_2/test_*.py
check_tests:
set -x; for test_file in $(TESTS); do echo $$test_file; check_test $$test_file; done;
Suppose we have the following dir structure:
dir_1
test_one.py
dir_1_1
test_two.py
dir_2
test_three.py
dir_2_1
test_four.py
This approach will yield dir_1/dir_1_1/test_two.py dir_2/test_three.py. I don't want to have to write both patterns for each of the dirs. Is there a pattern I can use that will fetch all the matching files in a dir and its subdirectories?
The ** meaning "search all subdirectories" is a special feature of some shells, but it's not a feature of POSIX shells. By using it your makefile will not work on systems which provide a standard POSIX shell as /bin/sh (such as, for example, Debian and its variants like Ubuntu). Even with shells where it does work often you have to specify a special option to enable it. In fact it's not actually working for you as seen by the output you get: it's being treated just as a single *.
The POSIX way to find all files in subdirectories is to use the find program. You could do something like this:
TEST_DIRS := dir_1 dir_2
TEST_FILES := $(foreach D,$(TEST_DIRS),$$(find $D -name test_\*.cpp -print))
check_tests:
set -x; for test_file in $(TEST_FILES); do echo $$test_file; check_test $$test_file; done
