I would like to do vue util test using jest, but since i used import statement, it keeps making errors. it says "SyntaxError: Cannot use import statement outside a module "
" at ScriptTransformer._transformAndBuildScript (node_modules/@jest/transform/build/ScriptTransformer.js:537:17)"
i've tried adding type:module to my package.json, transformIgnorePatterns to jest.config.js , and module to my script tag. none of them worked. i think it is related to version, as i am using vue 2 to get track of lessons im listening to. please take a look at my code
this is my package.json
{
"name": "jest-test",
"version": "0.1.0",
"private": true,
"scripts": {
"serve": "vue-cli-service serve",
"build": "vue-cli-service build",
"test:unit": "vue-cli-service test:unit",
"lint": "vue-cli-service lint"
},
"dependencies": {
"axios": "^1.2.3",
"core-js": "^3.6.5",
"vue": "^2.6.11",
"vuex": "^3.4.0"
},
"devDependencies": {
"@babel/preset-env": "^7.20.2",
"@vue/cli-plugin-babel": "^4.1.2",
"@vue/cli-plugin-eslint": "^4.1.2",
"@vue/cli-plugin-unit-jest": "^4.1.2",
"@vue/cli-plugin-vuex": "^4.1.2",
"@vue/cli-service": "^4.1.2",
"@vue/eslint-config-standard": "^5.1.2",
"@vue/test-utils": "^1.0.3",

"node-sass": "^4.12.0",
"sass-loader": "^8.0.2",
"vue-template-compiler": "^2.6.11"
}
}
this is my error code to test
<template>
<div>
{{ todo.title }}
</div>
</template>
<script>
import axios from "axios";
export default {
data() {
return {
todo: {},
};
},
created() {
this.fetchTodo();
},
methods: {
async fetchTodo() {
const { data } = await axios.get(
"https://jsonplaceholder.typicode.com/todos/1"
);
this.todo = data;
},
},
};
</script>
and this is testing code
import { shallowMount } from "@vue/test-utils";
import TodoTitle from "@/components/TodoTitle";
describe("TodoTitle Component", () =\> {
test("rendering", () =\> {
const wrapper = shallowMount(TodoTitle);
console.log(wrapper);
expect(wrapper.text()).toBe("");
});
});
