VSS Build vs Test issue

I’m creating a project for the ESP32 using the ESP-IDF framework in Visual Studio Code on MacOS.

I have some common code defined under lib which I include in my unit tests

├── id_list
│   ├── id_list.c
│   └── id_list.h
└── str_util
    ├── str_util.c
    └── str_util.h

The tests are in tests/

└── test_desktop
    ├── test_all.c
    ├── test_id_list.c
    ├── test_id_list.h
    ├── test_str_util.c
    └── test_str_util.h

My platform.ini is defined as follows:

platform = espressif32
board = esp32doit-devkit-v1
framework = espidf
monitor_speed = 115200
build_flags = -DCORE_DEBUG_LEVEL=1
test_ignore = test_desktop

platform = native

If I try to build the app using the Build icon at the bottom of the VSS window, it tries to build both my app and run the unit tests. This would be fine except for the fact that the src directory is not configured correctly for the tests and so it ends up including src/** files which I don’t want as it then complains with errors like

src/main.c:1:10: fatal error: 'freertos/FreeRTOS.h' file not found
#include "freertos/FreeRTOS.h"

If I manually build the app (without the tests)

$pio run -e esp32doit-devkit-v1

It correctly ignores the Test folder.

If I then run the tests manually or using the test icon at the bottom of the VSC window, it correctly ignores the src folder because of the test_ignore = test_desktop directive in plaformio.ini

Is there a way that I can configure the Build icon only to build the app and not to build the tests?

I think what I need is the ability to control the source files used to build each environment rather than relying on Platformio to try and do the right thing?

There are src_filter (docs) and other test options like test_build_project_src (docs) which you might want to have a look at.

Thanks @maxgerhardt. I did read the docs and try a few things out but without much success.

I’ll try again and report back if/when I have a better solution.

To control which environments are built when you hit the Build (All) button… have a look at default_envs.

Thanks for the tip. I added this at the start of my platformio.ini file and it now targets just the ESP32 codebase

default_envs = esp32doit-devkit-v1

I now see the other environment ignored which is exactly what I wanted.
