Run twister test in debug mode

[vincent_itk]

Hello,

I higly need to run twister unit tests in debug mode with breakpoints, step by step, spies and other debug tools in vscode. I did not find a way to do so.

Is anybody has an idea to run twister tests in debug mode ?

Many thanks by advance.

Hi,

This might depend on the platform you use. For native_sim it is like a normal west application 
west build -b native_sim -p -- -DCONFIG_DEBUG_OPTIMIZATIONS=y
west debug

Best regards,
Dejan

Go it running in debug mode in vscode with such config 

{
				"name": "Debug test",
				"type": "cppdbg",
				"request": "launch",
				"program": "${workspaceFolder:axi-v7}/twister-out/native_sim_native/host/lib/temp/lib.temp/zephyr/zephyr.exe",
				"cwd": "${workspaceFolder:axi-v7}/tests/lib/temp",
				"stopAtEntry": true,
			},

Adapt path to project is required.

Hard to get it working, sometimes vscode is really pain in the ...
