Importing JS modules (both CJS and ESM) doesn't work in GraalJS

[valdero]

Describe the bug Graaljs supports importing CommonJS or ECMAScript modules. However, due to maestro's GraalJsEngine implementation, no module imports work currently.

This most likely happens as Context.newBuilder("js") is missing .allowIO(true) here: https://github.com/mobile-dev-inc/maestro/blob/main/maestro-client/src/main/java/maestro/js/GraalJsEngine.kt#L83

See more info on module imports in the graalVM reference manual: https://www.graalvm.org/latest/reference-manual/js/Modules/#ecmascript-modules-esm

To Reproduce

1. Create two js files, e.g. main.js and env.mjs

// main.js
import { env } from "./two.mjs";

const testImport = () => {
  console.log(`${env.URL}`);
  return env.URL;
};

output.url = testImport();

// env.mjs
export const env = {
  URL: "https://example.com",
  ANOTHER_URL: "https://another-example.com",
};

2. Include main.js in e.g. main.yaml

   appId: com.example.myapplication
   jsEngine: graaljs
   ---
   - runScript: main.js
   - evalScript: ${console.log(output.url)}

3. Run maestro test main.yaml

Expected behavior Importing CommonJS or ECMAScript modules should work.

Screenshots Currently maestro tries to evaluate the import as a script.

Is there any traction on this issue? Our team is evaluating Maestro, and we're running into an issue similar to the above.

Hey @axelniklasson @igorsmotto any expectations for fixing this bug?

[bartekpacia]

hey @tiagodread! Bartek from mobile.dev team here. I see this issue is highly requested. I'll try to prioritize it in the coming weeks, because it looks like the benefit/effort required ratio is pretty good here.

In the meantime, of course, we're always happy to accept contributions.
