另一个解决方案:您也可以使用try/catch块

expect.assertions(1)
try {
    // if the element is found, the following expect will fail the test
    expect(getByTestId('your-test-id')).not.toBeVisible();
} catch (error) {
    // otherwise, the expect will throw, and the following expect will pass the test
    expect(true).toBeTruthy();
}

您可以使用react-native-testing-library "getAllByType"，然后检查该组件是否为空。优点是不必设置testd，也应该与第三方组件一起工作

 it('should contain Customer component', () => {
    const component = render(<Details/>);
    const customerComponent = component.getAllByType(Customer);
    expect(customerComponent).not.toBeNull();
  });

你必须使用querybytestd而不是getbytestd。

这里是一个代码示例，我想测试是否组件与“汽车”id不存在。

 describe('And there is no car', () => {
  it('Should not display car mark', () => {
    const props = {
      ...defaultProps,
      base: null,
    }
    const { queryByTestId } = render(
      <IntlProvider locale="fr" messages={fr}>
        <CarContainer{...props} />
      </IntlProvider>,
    );
    expect(queryByTestId(/car/)).toBeNull();
  });
});

// check if modal can be open
const openModalBtn = await screen.findByTestId("open-modal-btn");
fireEvent.click(openModalBtn);

expect(
  await screen.findByTestId(`title-modal`)
).toBeInTheDocument();


// check if modal can be close
const closeModalBtn = await screen.findByTestId(
  "close-modal-btn"
);
fireEvent.click(closeModalBtn);

const sleep = (ms: number) => {
  return new Promise((resolve) => setTimeout(resolve, ms));
};

await sleep(500);
expect(screen.queryByTestId("title-modal")).toBeNull();

我最近为一个笑话黄瓜项目写了一个检查元素可见性的方法。

希望对大家有用。

public async checknotVisibility(page:Page,location:string) :Promise<void> 
{
    const element = await page.waitForSelector(location);
    expect(element).not.toBe(location); 
}

对我来说(如果你想使用getbytestd):

expect(() => getByTestId('time-label')).toThrow()
