Raspberry Pi Pico unit testing

There is an simple project to understand how to run test for a project on RP2040-ETH board. Test file is very simple:

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

void tearDown(void) {}

int add(int a, int b)
{
    return a + b;
}

void test_calculator_addition(void) {
    TEST_ASSERT_EQUAL(32, add(25, 7));
}

void setup() {
    delay(2000);

    UNITY_BEGIN();
    RUN_TEST(test_calculator_addition);
    UNITY_END();
}

void loop() {
    delay(1000);
    Serial.println("Step");
}

If I try to run Test command, nothing happens

and there is a warning in verbose mode about diffrerent HWID than expected

It seems uploading works fine but there are no test results.

Am I doing something wrong?

Can you test the exact code from https://github.com/maxgerhardt/platform-raspberrypi/issues/28#issuecomment-1533664099?

Thanks for idea!
It works if configuration is changed from board = pico
to board = rpipico.
Trying to understand what the difference is…

4

That’s weird…

board = pico
board_build.core = earlephilhower

should be equivalent to

board = rpipico

otherwise I’ve made a mistake. Need to double check.

Other RP Pico board with the same sympthoms.
W5500-EVB-Pico works fine but configuration:

[env:5500_evb_pico]
platform = raspberrypi
board = wiznet_5500_evb_pico
framework = arduino
test_framework = unity
test_build_src = yes

doesn’t run unit tests.
Verbose mode shows equal warning:

Current device has a different ID that system expects

Maybe there is some magic option to run tests in W5500-EVB-Pico case?

6

Then set monitor_port = COMxxx accordingly and possibly delay after upload so that the referenced COM port has time to appear.

7

Monitor port is set propertly and delay after after upload was added. But it doesn’t help

8

That does pio devices show after the test executable has been uploaded? (Or when a regular firmware that uses the USB serial is uploaded)

9

Still the same

code of extra_script.py

Import("env")

def after_upload(source, target, env):
    print("Delay while uploading...")
    import time
    time.sleep(5)
    print("Done!")

env.AddPostAction("upload", after_upload)

code of ini file

[env:5500_evb_pico]
platform = raspberrypi
board = wiznet_5500_evb_pico
framework = arduino
test_framework = unity
test_build_src = yes
extra_scripts = post:extra_script.py

new delay row inside tests

void setup()
{
    delay(5000);
    UNITY_BEGIN();
    RUN_TEST(test_something);
    UNITY_END();
}
