/**
 * Annotation representing a type that should not be mocked.
 * When marking a type {@code @DoNotMock}, you should always point to alternative testing
 * solutions such as standard fakes or other testing utilities.
 *
 * Mockito enforces {@code @DoNotMock} with the {@link org.mockito.plugins.DoNotMockEnforcer}.
 *
 * If you want to use a custom {@code @DoNotMock} annotation, the {@link org.mockito.plugins.DoNotMockEnforcer}
 * will match on annotations with a type ending in "org.mockito.DoNotMock". You can thus place
 * your custom annotation in {@code com.my.package.org.mockito.DoNotMock} and Mockito will enforce
 * that types annotated by {@code @com.my.package.org.mockito.DoNotMock} can not be mocked.
