我正在更新我的反应应用到react-16,但我的所有测试刹车。我已经升级了enzyme,jest-enzyme,react-dom,安装了enzyme-adapter,创建了setupTest.ts酶文件,更新了jestconfig.js文件,但是我仍然收到错误。如果有人知道可能出了什么问题。
在执行npm ls时没有依赖项警告(相关的react测试)
这是我的jestconfig

写了问题而意识到了错误。在jestconfig.json中缺少以下内容
"snapshotSerializers": [
"enzyme-to-json/serializer" // <= this part
],
