如何使用@ testing-library / react测试蚂蚁设计日期选择器?

我在一个组件中有两个蚂蚁设计date pickers。我正在尝试更改和测试日期选择器的值,但无法在测试环境dom中找到日历输入。

日期选择器组件

import { DatePicker, Form } from "antd";
import React, { Component } from "react";

import moment from "moment";

class DatePickers extends Component {
  constructor(props) {
    super(props);
    this.state = {
      startDate: moment().subtract(1, "month"),
      startDateError: "",
      endDate: moment(),
      endDateError: "",
    };
  }

  onStartDateChange = (date) => {
    this.setState({
      startDate: date,
      startDateError: date ? "" : "Please select start date",
    });
  };

  onEndDateChange = (date) => {
    this.setState({
      endDate: date,
      endDateError: date ? "" : "Please select end date",
    });
  };

  render() {
    const { endDate, endDateError, startDate, startDateError } = this.state;

    return (
      <React.Fragment>
        <Form.Item
          validateStatus={startDateError ? "error" : ""}
          help={startDateError}
          htmlFor="startDate"
          label="Date From"
        >
          <DatePicker
            id="startDate"
            placeholder="Select Start Date"
            allowClear={false}
            onChange={this.onStartDateChange}
            defaultPickerValue={startDate}
            defaultValue={startDate}
            format="DD-MM-YYYY"
          />
        </Form.Item>
        <Form.Item
          validateStatus={endDateError ? "error" : ""}
          help={endDateError}
          htmlFor="endDate"
          label="To"
        >
          <DatePicker
            id="endDate"
            placeholder="Select End Date"
            allowClear={false}
            onChange={this.onEndDateChange}
            defaultPickerValue={endDate}
            defaultValue={endDate}
            format="DD-MM-YYYY"
          />
        </Form.Item>
      </React.Fragment>
    );
  }
}


export default DatePickers;

使用@ testing-library / react的测试用例

import { render, screen, waitFor } from "@testing-library/react";
import userEvent from "@testing-library/user-event";

test("date input value validation", async () => {
  const { container } = render(<DatePickers />);

  const startDateNode = screen.getByPlaceholderText(/select start date/i);
  const endDateNode = screen.getByPlaceholderText(/select end date/i);

  userEvent.click(startDateNode);

  const calendarInput = container.querySelector("ant-calendar-input");
  await userEvent.type(calendarInput, "");

  // assert
  expect(screen.getByText("Please select by start date")).toBeInTheDocument();
});

测试用例失败并引发错误

console.error node_modules/jest-environment-jsdom-fourteen/node_modules/jsdom/lib/jsdom/virtual-console.js:29
      Error: Not implemented: navigation (except hash changes)

版本:

"react" : "16.10.1",
"antd": "3.25.1",
"@testing-library/jest-dom": "5.7.0",
"@testing-library/react": "10.0.4",
"@testing-library/user-event": "10.1.2"

有什么办法可以断言吗?

我在antd v4上遇到了完全相同的问题。上面的解决方案是适当的,并且可以正常工作。我在Form.Item中使用多个日期选择器时遇到了麻烦,如果对Datepicker进行了自定义验证,请确保正确设置了日期格式。

    const startDate = screen.getByTestId("start-date");
    fireEvent.mouseDown(startDate);
    fireEvent.change(startDate, { target: { value: "10-12-2020" } });
    fireEvent.click(document.querySelectorAll(".ant-picker-cell-selected")[0]);

设置日期后,请根据您的验证,确保值的格式正确,并且还确保如果不使用时刻,则将所有日期字符串都设置为正在使用的任何库。我正在使用dayjs,有片刻的对象弄乱了其中一个日期。我花了几个小时才弄清楚。希望对您有所帮助。

    const endDate = screen.getByTestId("end-date");
    fireEvent.mouseDown(endDate);
    fireEvent.change(endDate, { target: { value: "10-25-2020" } });
    fireEvent.click(document.querySelectorAll(".ant-picker-cell-selected")[1]);

此错误似乎与日期选择器测试问题无关:https://github.com/jsdom/jsdom/issues/2112

无论如何,这就是我使用RTL测试Ant Design日期选择器的方法:

组件

shutil.make_archive(output, 'zip', input,allowZip64=True)

测试

<Form.Item colon={false} label={t('searchFields.creationDate.label')} name="creationDateRange">
  <RangePicker data-testid="creationDate" />
</Form.Item>

我试图使它更具可读性,并避免我不太喜欢document.querySelector部分,但是找不到其他解决方案。这肯定可以改善。

祝你好运
