Delay is causing crash

[tickietackie]

Hello, I am using the delay function which is causing the following crash when used within my tests.

Processing NativeTestWebserver in native environment

libc++abi: terminating with uncaught exception of type fakeit::UnexpectedMethodCallException

I tried if it will even crash for a very simple test, which it does for me:

#define NATIVE_TEST
#include <ArduinoFake.h>
#include <unity.h>

void test_wifi_password(void) {
  int test = 0;
  TEST_ASSERT_EQUAL(test, 0);
}

int main(int argc, char** argv) {
  UNITY_BEGIN();
  delay(2000);

  RUN_TEST(test_wifi_password);

  UNITY_END();

  return 0;
}

When I remove the delay(2000) it runs smoothly. Is this a general error, or can somebody explain the behavior?

I am running this on a Mac M1 and with the current master branch on GitHub.

You need to tell the mock to expect the call and what to do when the method is called.

void test_something_with_a_delay(){
  When(Method(ArduinoFake(), delay)).AlwaysReturn();
  delay(1000);
  Verify(Method(ArduinoFake(), delay).Using(1000)).Exactly(1);
}

Thanks for the explanation @wrong-kendall ..

@tickietackie as mentioned.. you have to mock the calls
