ArduinoFake is a simple mocking framework for Arduino.
ArduinoFake is based on FakeIt and can be used for testing both your arduino project natively.
You should include the following header in your test file:
#include <ArduinoFake.h>Assuming we have the following arduino code:
// src/main.cpp
void loop()
{
// turn the LED on (HIGH is the voltage level)
digitalWrite(LED_BUILTIN, HIGH);
// wait for a second
delay(100);
// turn the LED off by making the voltage LOW
digitalWrite(LED_BUILTIN, LOW);
// wait for a second
delay(100);
}It can be tested using ArduinoFake:
#include <ArduinoFake.h>
using namespace fakeit;
// test/test_main.cpp
void test_loop(void)
{
When(Method(ArduinoFake(), digitalWrite)).AlwaysReturn();
When(Method(ArduinoFake(), delay)).AlwaysReturn();
loop();
Verify(Method(ArduinoFake(), digitalWrite).Using(LED_BUILTIN, HIGH)).Once();
Verify(Method(ArduinoFake(), digitalWrite).Using(LED_BUILTIN, LOW)).Once();
Verify(Method(ArduinoFake(), delay).Using(100)).Exactly(2_Times);
