test runner regression in 19.2.0

[vhiairrassary]

Version

19.2.0

Platform

Darwin Victors-MacBook-Pro.local 22.2.0 Darwin Kernel Version 22.2.0: Fri Nov 11 02:08:47 PST 2022; root:xnu-8792.61.2~4/RELEASE_X86_64 x86_64

Subsystem

test runner

How to reproduce

Considering a file test.txt is available in the current directory, then the following script does not work anymore starting from 19.2.0 (it crashed on byteLength access):

const { readFile } = require("node:fs/promises");
const { test } = require("node:test");

test("test", async () => {
 const buffer = await readFile("./test.txt");
 console.log(buffer);
 console.log(buffer.byteLength);
});

Works in 19.1.0:

> nodenv shell 19.1.0 && node -v && node --test main.js
v19.1.0
TAP version 13
# Subtest: [redacted]/tmp/main.js
ok 1 - [redacted]/main.js
 ---
 duration_ms: 86.154689
 ...
1..1
# tests 1
# pass 1
# fail 0
# cancelled 0
# skipped 0
# todo 0
# duration_ms 89.07115

Does not work in 19.2.0:

> nodenv shell 19.2.0 && node -v && node --test main.js
v19.2.0
TAP version 13
# Subtest: [redacted]/tmp/main.js
 # <Buffer >
not ok 1 - [redacted]/tmp/main.js

It does not work with the latest available version (19.6.0)

Additional information

The following script works with all tested version (19.1.0, 19.2.0 & 19.6.0) when not using the --test flag:

const { readFile } = require("node:fs/promises");

(async () => {
 const buffer = await readFile("./test.txt");
 console.log(buffer);
 console.log(buffer.byteLength);
})()
