My first build native test does not success

[phunson]

Today, I just try to use native env. I try to find some complete reference how to create and do this. but does not get any complete step by step. this is what i did from collect information from many web site.

1). I crated "test.cpp" under /project/led/test/ as below. (copy code from some example)

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

void test_get_number_padding() {
TEST_FAIL();
}

void setup() {
Serial.begin(115200);
delay(2000);
UNITY_BEGIN();
RUN_TEST(test_get_number_padding);
UNITY_END();
}

void loop() {}

2. modify platformio.ini by add below

[env:native_test]
platform = native
test_build_src = yes

3. run CLI => pio test -e native_test -vvv then I got result as below

PS C:\Users\chaichan\Documents\PlatformIO\Projects\Led> pio test -e native_test

now I add more line on my test.cpp

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

and run cli again , and get new error as below
