Exercise: `MockSensor_nopoly` (Non-Polymorphic)¶

Requirement ¶

Implement a sensor class MockSensor_nopoly which does not access any real hardware to measure temperature. Rather, it has a method set_temperature() which can be used (by unit tests, ideally) to control the value that is returned by subsequent calls to get_temperature().

Use the following test to guide you through the implementation:

Download sensor-mock-nopoly-basic.cpp¶

#include <gtest/gtest.h>
#include <sensor-mock-nopoly.h>

TEST(sensor_mock_nopoly_suite, basic)
{
    MockSensor_nopoly ms(/*initial temperature:*/36.4);
    ASSERT_FLOAT_EQ(ms.get_temperature(), 36.4);
    ms.set_temperature(42.8);
    ASSERT_FLOAT_EQ(ms.get_temperature(), 42.8);
}
