调研方向

从 app/components/forms/inputs/date-time/tests/date-time.spec.tsx 开始,复现 await user.tab() 附近的警告。阅读 app/components/forms/inputs/date-time/date-time.tsx 和 app/components/forms/inputs/date/date.tsx,以跟踪日期选择器和表单更新。完成的标准是,有效输入测试可以执行 tab 和验证,且不会出现任何一个 act 警告。

描述

From my understanding, user actions do not need to be wrapped in act yet I'm still getting an error that state updates are happening outside of react for a datepicker component. When the user.tab() code is called below, that triggers a react-datepicker component to close and form state to update with validation.

Yet if I try to wrap the code inside act like it recommends, it says

Warning: The current testing environment is not configured to support act. All of our other act calls work fine so I think it's because it's "nesting" them since user events are already wrapped in act.

When testing, code that causes React state updates should be wrapped into act(...):

act(() => {
  /* fire events that update state */
});
/* assert on the output */

This ensures that you're testing the behavior the user would see in the browser. Learn more at https://reactjs.org/link/wrap-tests-with-act%s Manager
