unit test issue

Hello, When testing a component that uses Refine's useGo hook with the "show" action, we're encountering the following error: APage › should search automatically when there are filters on initial load [useGo]: [action: show] is not defined for [resource: a] Expected Behavior - The useGo hook should accept the "show" action for any resource and generate the appropriate URL - The test should run without throwing the routing error Current Behavior - The hook throws an error indicating that the "show" action is not defined for the "a" resource - This happens even though we've mocked the hook to handle this exact case Questions 1. What is the correct way to mock the useGo hook for testing components that use the "show" action? 2. Is there additional configuration needed to define available actions for resources in the test environment? 3. Are we missing any required setup in our test environment for Refine's routing to work properly?

Hi @Damla. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information in the knowledge sources, here are answers to your questions: 1. What is the correct way to mock the useGo hook for testing components that use the "show" action? The knowledge sources do not provide explicit guidance on mocking the useGo hook for unit tests. However, they clarify that useGo relies on the resource definitions provided to the <Refine /> component, specifically the actions (like "show") defined for each resource. If a resource does not have a "show" action defined in the resources array, calling useGo with { action: "show" } for that resource will result in an error: [useGo]: [action: show] is not defined for [resource: a] useGo documentation. 2. Is there additional configuration needed to define available actions for resources in the test environment? Yes. You must ensure that, in your test environment, the <Refine /> provider is rendered with a resources prop that includes the resource in question (e.g., "a") and that this resource has a "show" action defined. For example:

   <Refine
     resources={[
       {
         name: "a",
         show: "/a/:id",
         // ...other actions as needed
       },
     ]}
     // ...other required props
   >
     {/* your test component */}
   </Refine>

   <Refine
     resources={[
       {
         name: "a",
         show: "/a/:id",
         // ...other actions as needed
       },
     ]}
     // ...other required props
   >
     {/* your test component */}
   </Refine>

If the "show" action is missing from the resource definition, useGo will throw the error you described Relationship Between Resources and Routes. 3. Are we missing any required setup in our test environment for Refine's routing to work properly? Most likely, yes. The error suggests that the resource "a" does not have a "show" action defined in the resources array passed to <Refine /> in your test setup. Ensure that your test environment closely mirrors your production setup, especially regarding resource definitions and routing. This is essential for hooks like useGo to resolve actions and generate URLs correctly useGo documentation. --- Summary:
The error occurs because the "show" action is not defined for the resource in your test environment. To resolve this, make sure your <Refine /> provider in tests includes the correct resource definitions with all required actions. The knowledge sources do not provide details on mocking useGo directly, but correct resource configuration is essential for routing to work as expected. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai could you please provide an example of a proper unit test for a page that utilized link component of refine?

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Certainly! While the knowledge sources do not provide a full unit test example specifically for a page using Refine's <Link /> component, they do provide enough information to construct a basic test setup. Here’s how you can write a unit test for a page that uses Refine’s <Link /> component, based on the documented usage and general React Testing Library practices: Component Example (using Refine's <Link />):

// MyPage.jsx
import { Link } from "@refinedev/core";

export const MyPage = () => (
  <div>
    <h1>My Page</h1>
    <Link to="/posts">Go to Posts</Link>
  </div>
);

// MyPage.jsx
import { Link } from "@refinedev/core";

export const MyPage = () => (
  <div>
    <h1>My Page</h1>
    <Link to="/posts">Go to Posts</Link>
  </div>
);

Source: Refine Link Component Usage Test Example:

// MyPage.test.jsx
import React from "react";
import { render, screen } from "@testing-library/react";
import { Refine } from "@refinedev/core";
import routerProvider from "@refinedev/react-router";
import dataProvider from "@refinedev/simple-rest";
import { BrowserRouter } from "react-router-dom";
import { MyPage } from "./MyPage";

test("renders Link and navigates to /posts", () => {
  render(
    <BrowserRouter>
      <Refine
        dataProvider={dataProvider("<https://api.fake-rest.refine.dev">)}
        routerProvider={routerProvider}
        resources={[
          { name: "posts", list: "/posts" },
        ]}
      >
        <MyPage />
      </Refine>
    </BrowserRouter>
  );

  // Assert the link is rendered
  const link = screen.getByText("Go to Posts");
  expect(link).toBeInTheDocument();
  expect(link.getAttribute("href")).toBe("/posts");
});

// MyPage.test.jsx
import React from "react";
import { render, screen } from "@testing-library/react";
import { Refine } from "@refinedev/core";
import routerProvider from "@refinedev/react-router";
import dataProvider from "@refinedev/simple-rest";
import { BrowserRouter } from "react-router-dom";
import { MyPage } from "./MyPage";

test("renders Link and navigates to /posts", () => {
  render(
    <BrowserRouter>
      <Refine
        dataProvider={dataProvider("<https://api.fake-rest.refine.dev">)}
        routerProvider={routerProvider}
        resources={[
          { name: "posts", list: "/posts" },
        ]}
      >
        <MyPage />
      </Refine>
    </BrowserRouter>
  );

  // Assert the link is rendered
  const link = screen.getByText("Go to Posts");
  expect(link).toBeInTheDocument();
  expect(link.getAttribute("href")).toBe("/posts");
});

This test: - Wraps the component in <Refine /> with the required routerProvider and resources (as needed for routing to work). - Uses React Testing Library to render the page and assert the presence and correct href of the <Link /> component.

Note: The test above is constructed directly from the documented usage of <Link /> and the general testing approach for React Router and Refine. The knowledge sources do not provide a more advanced or interactive example (such as simulating navigation), but this covers the basic rendering and attribute check for the <Link /> component as described in the documentation Refine Link Component Usage.
