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')
))
