使用带有样式组件和主题的react-test-renderer (React Native)

import React from 'react';
import renderer from 'react-test-renderer';
import MyComponent from './MyComponent';

test('renders correctly', () => {
  const component = renderer.create(<MyComponent />);
  // ...
});

test('renders correctly', () => {
  const component = renderer.create(<MyComponent />);
  const tree = component.toJSON();
  expect(tree).toMatchSnapshot();
});

test('has correct styles', () => {
  const component = renderer.create(<MyComponent />);
  const styles = component.root.findByType(StyledComponent).props.style;
  expect(styles.backgroundColor).toBe('red');
});

test('renders correctly with dark theme', () => {
  const component = renderer.create(<MyComponent />, {
    theme: 'dark',
  });
  // ...
});
