Test Problem when I have a two plugin inside of another.

Here’s the revised bug report in English, incorporating the fact that the suggested Jest configuration did not resolve the issue:

🤔 Expected Behavior

When creating a custom plugin that depends on another custom plugin, the test suite should run without throwing parsing or configuration errors.

😯 Current Behavior

// Test Code  
import { HeaderContext } from './../../src/contexts/ig-header-context';
import { BindingSignaler } from 'aurelia-templating-resources';
import { NavigationInstruction } from 'aurelia-router';
import {ComponentTester, StageComponent} from 'aurelia-testing';
import {bootstrap} from 'aurelia-bootstrapper';
import { Container } from 'aurelia-framework';
const navigationInstructionMock: any = {
  params: {},
  queryParams: {},
  config: {
    name: 'testRoute'
  }
};
describe('HeaderContext', () => {

let signaler: BindingSignaler;

let container: Container;

let component: ComponentTester;

let headerContext: HeaderContext;

beforeEach(() => {

signaler = new BindingSignaler();

container = new Container();

headerContext = new HeaderContext(signaler);

container.registerInstance(HeaderContext, HeaderContext);

component = StageComponent

.withResources();

component.bootstrap(aurelia => {

aurelia.use.standardConfiguration();

aurelia.container = container;

return aurelia.use;

});

});
it('should resolve and use all dependencies correctly', done => {

component.create(bootstrap).then(() => {

headerContext.setInstruction(navigationInstructionMock);

headerContext.setPageTitle()

expect(headerContext.setInstruction).toHaveBeenCalled();

done();

}).catch(done.fail);

});
it('should initialize with default values', () => {

component.create(bootstrap).then(() => {

});
it('should set instruction and update title', () => {

config: { navModel: { title: 'Test Title' } }

} as NavigationInstruction;

headerContext.setInstruction(instruction);

expect(headerContext.instruction).toBe(instruction);

expect(headerContext.title).toBe('Test Title');

});
it('should reset properties and signal changes', () => {

jest.spyOn(signaler, 'signal');

headerContext.grupo = "test";

headerContext.sujeto = "test";

headerContext.propiedades = { key: "value" };

headerContext.reset();

expect(headerContext.grupo).toBe("");

expect(headerContext.sujeto).toBe("");

});
it('should update sujeto and signal change', () => {

jest.spyOn(signaler, 'signal');

expect(signaler.signal).toHaveBeenCalledWith("header-context-sujeto");

});
it('should update propiedades and signal change', () => {

jest.spyOn(signaler, 'signal');

const propiedades = { key1: "value1", key2: "value2" };

headerContext.actualizarPropiedades(propiedades);

expect(headerContext.propiedades).toEqual(propiedades);

expect(signaler.signal).toHaveBeenCalledWith("header-context-properties");

});
it('should truncate long propiedades values', () => {

const longValue = "a".repeat(51);

});

});

});

Running tests with Jest on a plugin that imports a class from another custom plugin results in the following error:

Test suite failed to run  
Jest encountered an unexpected token
Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax.
Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration.
By default "node_modules" folder is ignored by transformers.
Here's what you can do:

• If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it.

• If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript

• To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.

• If you need a custom transformation specify a "transform" option in your config.

• If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.
Details:
/home/carloscarniatto/Projects/Aurelia/FrontEnd/ig-components/node_modules/.pnpm/@intrigest+core@5.2.1/node_modules/@intrigest/core/src/utils/utils-dates.ts:2

import { es } from "date-fns/locale";

^^^^^^

SyntaxError: Cannot use import statement outside a module

The error occurs in the following code:

import { UtilsDates } from '@intrigest/core/src/utils/utils-dates';  

💁 Possible Solution

I have already tried the following Jest configuration, but it did not resolve the issue:

module.exports = {  
  transformIgnorePatterns: ["/node_modules/(?!@intrigest/core)"],  
  transform: {  
    "^.+\\.tsx?$": "ts-jest"  
  },  
  moduleNameMapper: {  
    "^.+\\.ts$": "ts-jest"  
  }  
};

🔦 Context

This issue prevents the execution of tests, blocking development and validation of features that depend on custom plugins.

💻 Code Sample

// File that triggers the error  
import { UtilsDates } from '@intrigest/core/src/utils/utils-dates';  
import { autoinject } from "aurelia-framework";
