How to use the @vue/compiler-core.NodeTypes.SIMPLE_EXPRESSION function in @vue/compiler-core

test('should transform into directive node and hoist value', () => {
    const { root, node } = transformWithStyleTransform(
      `<div style="color: red">`
    )
    expect(root.hoists).toMatchObject([
      {
        type: NodeTypes.SIMPLE_EXPRESSION,
        content: `{"color":"red"}`,
        isStatic: false
      }
    ])
    expect(node.props[0]).toMatchObject({
      type: NodeTypes.DIRECTIVE,
      name: `bind`,
      arg: {
        type: NodeTypes.SIMPLE_EXPRESSION,
        content: `style`,
        isStatic: true
      },
      exp: {
        type: NodeTypes.SIMPLE_EXPRESSION,
        content: `_hoisted_1`,
        isStatic: false</div>

test('HTML entities in interpolation should be translated for backward compatibility.', () => {
      const ast = parse('<div>{{ a &lt; b }}</div>', parserOptions)
      const element = ast.children[0] as ElementNode
      const interpolation = element.children[0] as InterpolationNode

      expect(interpolation).toStrictEqual({
        type: NodeTypes.INTERPOLATION,
        content: {
          type: NodeTypes.SIMPLE_EXPRESSION,
          content: `a &lt; b`,
          isStatic: false,
          isConstant: false,
          loc: {
            start: { offset: 8, line: 1, column: 9 },
            end: { offset: 16, line: 1, column: 17 },
            source: 'a &lt; b'
          }
        },
        loc: {
          start: { offset: 5, line: 1, column: 6 },
          end: { offset: 19, line: 1, column: 20 },
          source: '{{ a &lt; b }}'
        }
      })
    })

{
        type: NodeTypes.SIMPLE_EXPRESSION,
        content: `{"color":"red"}`,
        isStatic: false
      }
    ])
    expect(node.props[0]).toMatchObject({
      type: NodeTypes.DIRECTIVE,
      name: `bind`,
      arg: {
        type: NodeTypes.SIMPLE_EXPRESSION,
        content: `style`,
        isStatic: true
      },
      exp: {
        type: NodeTypes.SIMPLE_EXPRESSION,
        content: `_hoisted_1`,
        isStatic: false
      }
    })
  })
