我是Jest的新手，我正在尝试运行一个简单的单元测试，以确保所有内容都正确设置并且在编译期间遇到了很多问题 .
运行测试套件时，Jest成功找到我要测试的文件，并在第1行生成以下意外标识符错误消息 . 任何想法为什么会这样？缺少什么？我一直试图解决这个问题很长一段时间 .
/Users/foo/Sites/test/Test.spec.js:1
({"Object.":function(module,exports,require,__dirname,__filename,global,jest){import Test from './Test.vue';
^^^^
SyntaxError: Unexpected identifier
at ScriptTransformer._transformAndBuildScript (node_modules/jest-runtime/build/script_transformer.js:403:17)
注意，删除import语句一起成功运行测试 . 但是，我设置Jest的全部原因是测试vue组件 .
Test.vue
export default {
name: 'test',
components: { },
data() {
return {
}
},
methods: {
helloWorld() {
return 'hello world';
}
}
}
Test.spec.js
import Test from './Test.vue'
describe('Test',() => {
it('test', () => {
expect(true).toBe(true);
});
});
