Can not see the unit test results in platformio for esp32

Development Platforms
1

I want to write unit tests for my programs in platformio for esp32. I use Arduino framework. I have a ESP Prog ( https://www.digikey.com/en/products/detail/espressif-systems/ESP-PROG/10259352 ) . I used zadig to change ftdi driver as mentioned here : Zadig Driver Installation Guide

I can debug my programs through jtag port but when I run Test command every thing halt after platformio shows “If you don’t see any output for the first 10 secs, please reset board (press reset button)” .

I used a simple sample as following:
main :

#include <Arduino.h>

void setup()
{
    Serial.begin(9600);
}

void loop()
{
    Serial.println("Hello world!");
    delay(1000);
}

test program :

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

String STR_TO_TEST;

void setUp(void) {
    // set stuff up here
    STR_TO_TEST = "Hello, world!";
}

void tearDown(void) {
    // clean stuff up here
    STR_TO_TEST = "";
}

void test_string_concat(void) {
    String hello = "Hello, ";
    String world = "world!";
    TEST_ASSERT_EQUAL_STRING(STR_TO_TEST.c_str(), (hello + world).c_str());
}

void test_string_substring(void) {
    TEST_ASSERT_EQUAL_STRING("Hello", STR_TO_TEST.substring(0, 5).c_str());
}

void test_string_index_of(void) {
    TEST_ASSERT_EQUAL(7, STR_TO_TEST.indexOf('w'));
}

void test_string_equal_ignore_case(void) {
    TEST_ASSERT_TRUE(STR_TO_TEST.equalsIgnoreCase("HELLO, WORLD!"));
}

void test_string_to_upper_case(void) {
    STR_TO_TEST.toUpperCase();
    TEST_ASSERT_EQUAL_STRING("HELLO, WORLD!", STR_TO_TEST.c_str());
}

void test_string_replace(void) {
    STR_TO_TEST.replace('!', '?');
    TEST_ASSERT_EQUAL_STRING("Hello, world?", STR_TO_TEST.c_str());
}

void setup()
{
    delay(10000); // service delay
    UNITY_BEGIN();

    RUN_TEST(test_string_concat);
    RUN_TEST(test_string_substring);
    RUN_TEST(test_string_index_of);
    RUN_TEST(test_string_equal_ignore_case);
    RUN_TEST(test_string_to_upper_case);
    RUN_TEST(test_string_replace);

    UNITY_END(); // stop unit testing
}

void loop()
{
}

output:

If you don't see any output for the first 10 secs, please reset board (press reset button)

The default unit test transport protocol is via Serial. It will not switch to transporting the results via JTAG, it doesn’t even have an implementation for that.

On the other hand, your ESP-PROG is a dual-interface device, with 1 UART and 1 JTAG. Did you hook up the UART of the esp-prog to the ESP32 properly? TX should be IO1 of the ESP32 chip.

Actually I didn’t know the necessity of connecting tx0 to the programmer. after I connected it the outputs printed on the console.
