Hi, sorry for the noob question here. I am new to testing. I wanted to know how can we cover the API test with RNTL? For example, I want to test the following.

const res = await sendFeedback(feedbackObj);
  if (res.data) {
    showMessage({
      message: 'Thanks for your feedback!',
      type: 'success',
      icon: 'success',
    });
    setIsSubmitting(false);
    Keyboard.dismiss();
    navigation.goBack();
  } else {
    showMessage({
      message: 'Something went wrong. Please try again later.',
      type: 'danger',
      icon: 'danger',
    });
    setIsSubmitting(false);
  }

Here I want to put a test condition for the success branch. Is this a right thing to do with RNTL or I should think in a different way? Thanks a lot!
