TypeError: getiitems [props. properties].(动作)不是函数

Question

我是新的反应测试，我试图验证反应功能组件在那里，用这个代码，但由于某种原因，它是抱怨别的东西TypeError: getItems [props。动作]不是函数

是否有任何帮助/建议，以验证组件是否存在?

interface SelectionListProps {
actionArgs?: string | undefined;
action: string;
name?: string;
identifier?: string;
classes: {
button_basic: string;
formControl: string;
selectionCard: string;
};
}
export const SelectionList: React.FC<SelectionListProps> = (
props
) => {

const dispatch = useDispatch();
const getItems = {
analysers: (site: any) => dispatch(getAnalysers(site)),
sites: (site: any) => dispatch(getSites()),
} as any;
const initializeCollapses = () => {

};
useEffect(() => {
getItems[props.action](props.actionArgs).then(() => {
initializeCollapses();
});
}, []);

return (
<List component="div" data-testid="SelectionListt">
</List>
);
};

my testing code:

import React from "react";
import { expect } from "@jest/globals";
import { render, screen, cleanup, fireEvent } from "@testing-library/react";
import { SelectionList } from "../SelectionList";
import { Provider } from "react-redux";
import { store } from "../../redux/store";
import "@testing-library/jest-dom/extend-expect";
function handleUpdateClick(event: any, type = "") {}
test("test", () => {
render(
<Provider store={store}>
<SelectionList
classes={{ button_basic: "", formControl: "", selectionCard: "" }}
action={""}
actionArgs={""}

/>
</Provider>
);
const SelectionCardElement = screen.getByTestId("SelectionListt");
expect(SelectionCardElement).toBeInTheDocument();
});

您正在传递action名称的空字符串，但getItems[""]不匹配任何函数，因为getItems的值为:

const getItems = {
analysers: (site: any) => dispatch(getAnalysers(site)),
platforms: (site: any) => dispatch(getPlatforms(site)),
brokers: (site: any) => dispatch(getBrokers(site)),
cameras: (site: any) => dispatch(getCameras(site)),
sites: (site: any) => dispatch(getSites()),
}

也是的所有函数getItems，但最后一个，期望一个site参数。然而，目前您正在为参数传递一个空字符串。在sites函数中，您可以删除未使用的站点参数
