store.getActions()在部分测试中无法返回action的问题求助

我在测试Redux Action是否正确派发时，发现store.getActions()方法在一个测试用例中能正常返回结果，但在另一个用例里完全拿不到任何数据。不过失败的那个用例里，用getByText这类基础测试方法配合mock-store数据测试组件是正常的。

失败的测试用例代码 #

test('setButtons action dispatched on button click', () => {
  const store = mockStore(initialState);

  const { getByText } = render(
    <Provider store={store}>
      <MemoryRouter>
        <Comments />
      </MemoryRouter>
    </Provider>
  );
  
  const button = getByText('Posts')
  fireEvent.click(button);

  const actions = store.getActions();
  const expectedAction = setButtons('Show Comments');
  console.log('Expected Action Comment:', expectedAction);  
  console.log('Actions Comment:', actions);

  expect(actions).toContainEqual(expectedAction);
});

对应日志输出 #

console.log                                                                                                                                                                                                 
  Expected Action Comment: { type: 'comments/setButtons', payload: 'Show Comments' }                                                                                                                        

            
  at Object.<anonymous> (src/features/Comments/__test__/Comments.test.js:90:11)                                                                                                                             

            
console.log
  Actions Comment: []

正常工作的测试用例代码 #

test('setButtons action dispatched on button click', () => {
  const store = mockStore(initialState);

  const { getAllByText } = render(
    <Provider store={store}>
      <MemoryRouter>
        <Posts />
      </MemoryRouter>
    </Provider>
  );
  
  const button = getAllByText('Comments')
  fireEvent.click(button[0]);

  const actions = store.getActions();
  const expectedAction = setButtons('Hide Comments');
  console.log('Expected Action Posts:', expectedAction);  
  console.log('Actions Posts:', actions);

  expect(actions).toContainEqual(expectedAction);
});

对应日志输出 #

console.log
  Expected Action Posts: { type: 'comments/setButtons', payload: 'Hide Comments' }

  at Object.<anonymous> (src/features/Posts/__test__/Posts.test.js:108:11)

console.log
  Actions Posts: [
    { type: 'comments/setSelectedComments', payload: undefined },
    { type: 'comments/setSelectedCommentsTitle', payload: 'Post 1' },
    { type: 'comments/setButtons', payload: 'Hide Comments' }
  ]
