pio test -c parameter is not working on esp8266

[roipoussiere]

What kind of issue is this? PlatformIO Core

Configuration

Operating system: Ubuntu 21.10

PlatformIO Version: PlatformIO Core, version 6.0.1

Description of problem

The command pio test -c some_file.ini works for esp32 boards, but not on esp8266 boards.

Steps to Reproduce

1. create a file named custom.ini and fill it with a esp32 config:

[env]
framework = arduino
platform = espressif32
board = esp32dev

[env:pins]
test_filter = test_pins

2. build the test: pio test -c custom.ini --without-uploading --without-testing -v: the build works as expected.
3. now edit the custom.ini file with a esp8266 config:

[env]
framework = arduino
platform = espressif8266
board = esp01

[env:pins]
test_filter = test_pins

4. build the test: pio test -c custom.ini --without-uploading --without-testing -v: now the build fails with this error:

Actual Results

Building stage has failed, see errors above. Use `pio test -vvv` option to enable verbose output.

Expected Results

The test command should be functional whatever the target board.

If problems with PlatformIO Build System:

The content of platformio.ini: see above

Source file to reproduce issue:

It seems that the source file doesn't matter, but here is a minimal test file:

#include <unity.h>

void test_pass() {
	TEST_PASS();
}

void setup() {
	delay(2000); // wait until the test runner establishes serial connection
	UNITY_BEGIN();
	RUN_TEST(test_pass);
	UNITY_END();
}

void loop() {}
void setUp() {}
void tearDown() {}

Can't reproduce this issue. You have posted absolutely different custom.ini.

Can't reproduce this issue. You have posted absolutely different custom.ini.

I don't understand your message and the reason of the wontfix, could you add more details?

I checked my .ini files, their contents match what I shared above.

Should I add more details to allow you to reproduce the issue?
Do you think it's something related to esptool?

I also reproduced this on a fresh python venv, with only platformio installed.

[roipoussiere]

Ok, those lines on the stacktrace I shared:

CONFIGURATION: https://docs.platformio.org/page/boards/espressif8266/esp01.html
PLATFORM: Espressif 8266 (4.0.0) > Espressif Generic ESP8266 ESP-01 512k
HARDWARE: ESP8266 80MHz, 80KB RAM, 512KB Flash
PACKAGES: 
 - tool-esptool @ 1.413.0 (4.13) 
 - tool-esptoolpy @ 1.30000.201119 (3.0.0)

are indeed not present when I reproduce the error with the .ini I shared, I edited my first post.

Could also reproduce this. When custom.ini is named platformio.ini, everything works. When doing -c custom.ini, it fails with the error above on this line:
https://github.com/esp8266/Arduino/blob/f5ef02d6431626f67b0a6b960479ee37e87af20b/tools/platformio-build.py#L138

platform.get_package_dir("toolchain-xtensa") returns None instead of the correct path to the packages dir.

Thanks! This is a bug. Please re-test with pio upgrade --dev.
