// The Abstract Class We Are Testing
public Abstract class Car {
    public String getDescription(String color) {
        return "sleek "+color+" car";
    };
}

// Test Contained in Separate Class Below
Car blueCar = mock(Car.class);

given(blueCar.getDescription(anyString())).willCallRealMethod();

assertThat(blueCar.getDescription("blue"), contains("blue"));
