TEST Embedded Arduino Micro (ClearCommError)

[ArthurREGNARD]

Configuration

Operating system: Windows 10

PlatformIO Version (platformio --version): PlatformIO Core, version 5.1.1

Description of problem

Got an error when testing on embedded Arduino Micro board.

Steps to Reproduce

1. Upload the blink source code : No error and working
2. Source test code : https://docs.platformio.org/en/latest/tutorials/core/unit_testing_blink.html#tutorial-unit-testing-blink
3. run ``platformio test`

Actual Results

$ platformio test -e micro

============================================================

An unexpected error occurred. Further steps:

* Verify that you have the latest version of PlatformIO using
  `pip install -U platformio` command

* Try to find answer in FAQ Troubleshooting section
  https://docs.platformio.org/page/faq.html

* Report this problem to the developers
  https://github.com/platformio/platformio-core/issues

============================================================

Expected Results

Test run on my Arduino Micro board.

If problems with PlatformIO Build System:

The content of platformio.ini:

[env:micro]
platform = atmelavr
board = micro
framework = arduino

Source file to reproduce issue:

#include <Arduino.h>
#include <unity.h>

void test_led_builtin_pin_number(void)
{
    TEST_ASSERT_EQUAL(LED_BUILTIN, 13);
}

void test_led_state_high(void)
{
    digitalWrite(LED_BUILTIN, HIGH);
    TEST_ASSERT_EQUAL(digitalRead(LED_BUILTIN), HIGH);
}

void test_led_state_low(void)
{
    digitalWrite(LED_BUILTIN, LOW);
    TEST_ASSERT_EQUAL(digitalRead(LED_BUILTIN), LOW);
}

void setup()
{
    delay(2000);
    UNITY_BEGIN();
    RUN_TEST(test_led_builtin_pin_number);

    pinMode(LED_BUILTIN, OUTPUT);
}

uint8_t i = 0;
uint8_t max_blinks = 5;

void loop()
{
    if (i < max_blinks)
    {
        RUN_TEST(test_led_state_high);
        delay(500);
        RUN_TEST(test_led_state_low);
        delay(500);
        i++;
    }
    else if (i == max_blinks)
    {
        UNITY_END();
    }
}

Additional info

[maxgerhardt]

I think it has the same route cause as #3742.

[ArthurREGNARD]

Got a temporary patch.
Run the commande in two step:

1. Build and Upload firmware.
2. Testing firmware.

Done with the commande :
platformio test -e micro -f test_embedded --without-testing && platformio test -e micro -f test_embedded --without-building --without-uploading
Result :

$ platformio test -e micro --without-testing -f test_embedded && platformio test -e micro --without-building --without-uploading -f test_embedded
