How to debug a unit test?

[gschwaer]

I wrote a unit test according to https://docs.zephyrproject.org/latest/develop/test/ztest.html#quick-start-unit-testing and now I want to debug it. If I use gdb on the output binary testbinary it says No debugging symbols found in [FILE] (file also doesn't list it as having debug info).

I tried adding CONFIG_DEBUG=y and CONFIG_DEBUG_INFO=y to the proj.conf, but that had no effect.

So how can I debug unit tests?

Btw, I'm executing twister like so: west twister --platform unit_testing --testsuite-root path_to/my_tests

I found a workaround, but I don't think that this is the right way to go about this: Add set(CMAKE_BUILD_TYPE "Debug") at the top of the CMakeLists.txt.

Is this a bug in the build system for unit_testing?

Ok, nvm, I found out that this was fixed upstream in 1a16ace

So the solution is:
a) upgrade to a newer Zephyr version
b) plaster set(CMAKE_BUILD_TYPE "Debug") at the top of you tests' CMakeLists.txt
