Jest React Testing Library Should I Wrap Rerender With Act

Jest React Testing Library Should I Wrap Rerender With Act - The problem may be related to this issue, in which async logic (such as a useeffect) is triggering state changes. To avoid some of the boilerplate, you could use a library like react testing library, whose helpers are wrapped with act(). When testing, code that causes react state updates should be wrapped into act(.): While act() is powerful and offers a greater degree of control, findby queries provide a more elegant and less verbose way of testing asynchronous operations in react. /* fire events that update state */ this ensures that you're testing the behavior the user. Jest and react testing library are frequently used together for unit testing and snapshot testing. To prepare a component for assertions, wrap the code rendering it and performing updates inside an act() call. If you're using a library like react testing library, then things like the render function are already wrapped in act(), and you generally will not need to use it explicitly. Try using await inside act. In the source code, fireevent is already wrapped in act().
