How can I solve the issue of 'failed to resolve import in '@/...'" vitest?

Question

This is the error I got. There is a problem with the file path I defined in the "vite.config.ts" file. Can you help me?

Error Log

Error Message:

FAIL  tests/utils/ConvertFromDomainToCountryCode.test.ts [ tests/utils/ConvertFromDomainToCountryCode.test.ts ]
Error: Failed to resolve import "@/constant" from "src/assets/ts/_utils/ConvertFromDomainToCountryCode.ts". Does the file exist?

ConvertFromDomainToCountryCode.test.ts file

import { describe, expect } from "vitest";
import { SetFlags } from "../../src/assets/ts/_utils/ConvertFromDomainToCountryCode.ts";

describe("Convert From Domain To CountryCode", () => {
  test("function defined", () => {
    expect(SetFlags).toBeDefined();
  });
});

Here it works fine when I make the file path "../../../constant/index".

ConvertFromDomainToCountryCode.ts file

import { COUNTRY_INFO } from "@/constant";

Here i added "alias"

vite.config.ts file

import { fileURLToPath, URL } from "node:url";

import { defineConfig } from "vite";
import vue from "@vitejs/plugin-vue";
import { resolve, dirname } from "node:path";
import vueJsx from "@vitejs/plugin-vue-jsx";

export default defineConfig({
  plugins: [
    vue(),
    vueJsx()
  ],
  resolve: {
    alias: {
      "@": fileURLToPath(new URL("./src", import.meta.url))
    }
  },
  base: "/"
});

Just waiting for the path of the file to be found

Answer 1

I solve this error. I add this code in vitest.config.ts file.

resolve: {
  alias: [{ find: "@", replacement: resolve(__dirname, "./src") }]
}
