What steps will reproduce the bug?
This issue was observed inside the nodejs source code, when tying to create a benchmark
create a file benchmark/test_runner/mock-module.js
now copy this code
"use strict";
const { test } = require("node:test");
function main() {
test(async (t) => {
console.log("benchmark");
try {
// Create a mock module
t.mock.module('axios', {
namedExports: {
get: (url) => url
}
});
} catch (e) {
console.error(e);
}
console.log("end");
});
}
main()
now run this using ./node --experimental-test-module-mocks benchmark/test_runner/mock-module.js
You will get this output
benchmark

As you can we we are trying to create a mock 'axios' module but we receive the error Cannot find package 'axios', which is unexpected as we are not even importing the module. The error is occurring because of the line t.mock.module
How often does it reproduce? Is there a required condition?
dose not need any special condition
What is the expected behavior? Why is that the expected behavior?
should create a mock module called axios
What do you see instead?
their is an error, saying package 'axios' not found, which is very unexpected

Direzione di ricerca
Inizia da benchmark/test_runner/mock-module.js e dalla chiamata t.mock.module, quindi segui il mock loader in internal/test_runner/mock/loader.js e il relativo percorso di risoluzione dei moduli. Riproduci il comportamento con ./node --experimental-test-module-mocks benchmark/test_runner/mock-module.js; il lavoro è completato quando il mock può essere creato senza l’errore imprevisto di risoluzione di axios.
