Hey,

I like to do some code tests for parts of my firmware. I struggling to find out how to setup testing.

There is some explanation at

https://docs.zephyrproject.org/1.12.0/subsystems/test/ztest.html

but I am missing something like a tutorial like "how to integrate unit testing into my project?".


So I am asking if you can help me to get a clear top down approach.

Let's setup a fictional project, called myProject. This project defines an own board "myBoard" based on the stm32f412.

For this board we wrote some firmware containing several code files and a config.

We created a ztest that should check some part of the firmware.

The filesystem structure looks like that:

myProject/

myProject/myBoard/

myProject/myBoard/myBoard.dts

myProject/myBoard/myBoard_defconfig

myProject/src/

myProject/src/drv/myDrv.c

myProject/src/drv/myDrv.h

myProject/src/main.c

myProject/CMakeLists.txt

myProject/prj.conf

myProject/myTest/

myProject/myTest/testa.c

myProject/myTest/main.c


@CMakeLists.txt

cmake_minimum_required(VERSION 3.10)

set(BOARD "myBoard")
set(BOARD_ROOT "${CMAKE_SOURCE_DIR}")

include($ENV{ZEPHYR_BASE}/cmake/app/boilerplate.cmake NO_POLICY_SCOPE)
project(NONE)

list(APPEND INC
src/drv/
)

list(APPEND SRC
src/drv/myDrv.c
src/main.c
)

target_sources(app PRIVATE ${SRC})

target_include_directories(app PRIVATE ${INC})

@prj.conf

# CONFIG_TEST=y
# CONFIG_ZTEST=y
# CONFIG_DEBUG=y

CONFIG_STDOUT_CONSOLE=y
CONFIG_PRINTK=y
CONFIG_SYS_LOG=y
CONFIG_SYS_LOG_SHOW_COLOR=y

CONFIG_UART_LINE_CTRL=y
CONFIG_SEGGER_SYSTEMVIEW=y

How do I need to modify the cmake, configs and file structure to run the test while building the firmware?
