【中文标题】顺风复杂类(焦点等)和苗条项目中的笑话出错。仅在运行测试时【英文标题】:Error with tailwind complex class (focus, etc.) and jest in svelte project. Only when running tests 【发布时间】:2021-10-19 22:50:27 【问题描述】:在 .svelte 文件中运行应用程序时,<style>
中的 CSS 可以完美运行。
当用 jest 执行测试时,如果我使用这样的简单 CSS 选择器就可以了:
<style lang="postcss" type="text/postcss">
form input
@apply shadow appearance-none border border-transparent rounded w-full py-2 px-3 text-gray-700 leading-tight;
但是如果我添加一个像焦点这样的复杂类:
form input
@apply focus:ring-2 shadow appearance-none border border-transparent rounded w-full py-2 px-3 text-gray-700 leading-tight;
我遇到了这个错误:

【问题讨论】:
尝试转义:
字符 - \:
【参考方案1】:
所以我发现...
我需要在 jest 部分的 package.json 中添加 "preprocess": true
:
""jest":
"transform":
"^.+\\.svelte$": [
"svelte-jester",
"preprocess": true
],
"^.+\\.js$": "babel-jest"
