示例1: it

it('should move static apis under "Taro"', function () {
  const code = `
    import { noop } from '@tarojs/taro-h5';
    noop;
    noop();
  `

  const result = babel.transform(code, { plugins: [pluginOptions] })
  expect(result.code).toMatchSnapshot();

  const ast = result.ast as t.File
  const body = ast.program.body as [t.ImportDeclaration, t.ExpressionStatement]
  expect(t.isImportDeclaration(body[0])).toBeTruthy()
  expect(t.isExpressionStatement(body[1])).toBeTruthy()
  const defaultImport = body[0].specifiers.find(v => t.isImportDefaultSpecifier(v))
  expect(defaultImport).toBeTruthy()

  const taroName = defaultImport!.local.name
  let memberExpression = body[1].expression
  if (t.isCallExpression(body[1])) {
    memberExpression = (body[1].expression as t.CallExpression).callee
  }
  expect(memberExpression).toMatchObject(t.memberExpression(
    t.identifier(taroName),
    t.identifier('noop')
