Question

在我的代码中，我在“OK”点击System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.Http.WinHttpException: A connection with the server could not be established at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.ConfiguredTaskAwaitable`1.ConfiguredTaskAwaiter.GetResult() at System.Net.Http.WinHttpHandler.<StartRequest>d__105.MoveNext() --- End of inner exception stack trace --- at Google.Apis.Http.ConfigurableMessageHandler.<SendAsync>d__43.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.ConfiguredTaskAwaitable`1.ConfiguredTaskAwaiter.GetResult() at System.Net.Http.HttpClient.<FinishSendAsync>d__58.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Google.Apis.Requests.ClientServiceRequest`1.<ExecuteUnparsedAsync>d__26.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Google.Apis.Requests.ClientServiceRequest`1.<ExecuteAsync>d__23.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Google.Apis.Requests.ClientServiceRequest`1.<ExecuteAsync>d__22.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at GoogleTranslate.Client.GoogleTranslateClient.<GoogleTranslateAsync>d__3.MoveNext() in C:\myProject\src\GoogleTranslate.Client\GoogleTranslateClient.cs:line 41提示时触发回调，我想测试是否触发了回调。

在window.confirm中，我可以通过以下方式存储sinon函数：

window.confirm

我有没有办法在Jest中实现这种存根？

Answer 1

在开玩笑中，您可以使用global覆盖它们。

global.confirm = () => true

正如在每个测试文件在其自己的过程中运行一样，您不必重置设置。

Answer 2

我刚刚使用了开玩笑，它对我有用：

   it("should call my function", () => {
      // use mockImplementation if you want to return a value
      window.confirm = jest.fn().mockImplementation(() => true)

      fireEvent.click(getByText("Supprimer"))

      expect(window.confirm).toHaveBeenCalled()
}

Answer 3

为了消除模拟泄漏到其他测试的机会，我使用了一次模拟：

jest.spyOn(global, 'confirm' as any).mockReturnValueOnce(true);

Jest中的Stubbing窗口函数
