string list as argument to SET_TESTS_PROPERTIES()?

Code
1

I have some cmake code that generates test names. It has a base-test name followed by some identifier. An example would be this: which is in a loop and the id’s and args are different.

ADD_TEST (NAME “${APT_TEST_NAME}-${TEST_ID}” COMMAND “${MY_COMMAND}” ${ARG_LIST})

This works just fine in that I can execute that test in CTEST.

What I want to do is to serialize all those base tests even when running with a large ctest_parallel_level.

I’ve tried created a string list of all the related ${APT_TEST_NAME}-${TEST_ID} like this:

STRING(APPEND TEST_LIST “${APT_TEST_NAME}-${TEST_ID}”)

– but I can’t seem to cajole SET_TESTS_PROPERTIES() to understand a test list. I’ve monkeyed with quote/no-quotes, etc.

Example:

SET_TESTS_PROPERTIES(“${TEST_LIST}” PROPERTIES RUN_SERIAL TRUE)

CMAKE tells me each time that the conjoined test names is a test that cannot be found.

Is there a better way to tackle this? Or am I on the right track but have missed a subtle nuance?

If you want a list to be treated as a list, expand it without quotes. This should work:

set_tests_properties(${TEST_LIST} PROPERTIES RUN_SERIAL TRUE)

Try with list(APPEND …) instead of string(APPEND …)

Geez. I’m an idiot. I meant to use LIST … sometimes all the CMAKE primitives look the same!
