Unit tests with unity

PlatformIO IDE

I am trying to run unity tests with Unity and I am getting the error below

I am running the task test on Platformio

The code is (UniversalRemoteControlTest.cpp):

#include <unity.h>
#include <IUniversalRemoteControl.h>

RemoteControl remoteControl;

void setUp(void) {
    remoteControl = RemoteControl();
    remoteControl.addCode(0x123, "up");
}

// void tearDown(void) {
// // clean stuff up here
// }

void test_should_add_code(void) {
    //boolean test = "up".equals(remoteControl.hasCode(0x123));
    TEST_ASSERT_TRUE(true);
} 

int main(int argc, char **argv) {
    /*
    UNITY_BEGIN();
    RUN_TEST(test_should_add_code);
    UNITY_END();
*/
    return 0;
}

I am running on Mac VSCode

platformio.ini:

And which file is that and where is it? What’s the platformio.ini?

3

Updated on the main question, tks

4

Isn’t the file just in the wrong place? What happens when you move lib/xxx/test/UniverstalRemoteControlTest.cpp to just test/?

5

@maxgerhardt, moving the file fixed that error, but dependencies are not working properly.
I dig a bit more.

Any chance I can make the test work from the original location?

Tks

6

All but the first line must be indented by at least two spaces to be picked up correctly.

Does it help if you also add UniversalRemoteControl in that list?

7

@maxgerhardt,
there are. It was just pasting here that was wrong. Tks

See the error below.
Both environments fail with different errors

What is interesting is that the build passes: (if fails on Native because it misses Arduino.h, but that kind of makes sense)

I think there’s some issue with C declarations of functions with extern "C" that might happen somwehere. Are the files in lib/ and test/ available for review?

@maxgerhardt,

I tried to create a project from scratch using CLI and it still doesn’t work
