如何模拟开玩笑/酶中的单击选项卡

Question

我想编写一个简单的测试1-单击选项卡2-查看状态正在复活3- TAB Content Real已更改

我的问题是wen simulate click已发射，但setState不起作用

test('selected tab change when click on tab', () => {
  const wrapper = shallow(<MyComponent />)
  const walletTab1 = findByTestAttr(wrapper, 'wallet-tab-1').dive().dive().dive().dive()

  console.log('shaloww',walletTab1.debug())
  walletTab1.simulate('click')
  const walletTabContainer = findByTestAttr(wrapper, 'wallet-tab-container-1')
  expect(walletTabContainer.length).toBe(1)
})

myComponent

        <AppBar position="static" color="default" data-test="component-wallet">
          <Tabs
            data-test="wallet-tabs"
            value={selectedTab}
            onChange={(event, value) => {
               this.setState({selectedTab: val})
            }}
            indicatorColor="primary"
            textColor="primary"
            variant="scrollable"
            scrollButtons="auto"
          >
            <Tab data-test="wallet-tab-0" label="Item One" />
            <Tab data-test="wallet-tab-1" label="Item Two" />
            <Tab data-test="wallet-tab-2" label="Item Three" />
          </Tabs>
        </AppBar>
        {selectedTab === 0 && <TabContainer data-test="wallet-tab-container-0">Item One</TabContainer>}
        {selectedTab === 1 && <TabContainer data-test="wallet-tab-container-1">Item Two</TabContainer>}
        {selectedTab === 2 && <TabContainer data-test="wallet-tab-container-2">Item Three</TabContainer>}

单击后应为状态(SelectedTab(更新1

Answer 1

onChange={(event, value) => {
  this.setState({selectedTab: val})
}}

您的代码中没有称为 val的东西，函数的参数为 value。我认为这就是问题。
