From 50394c87b591f3ede0bb076581f8fbf93c3844e4 Mon Sep 17 00:00:00 2001 From: Nicolas DUBIEN Date: Wed, 22 May 2024 20:22:15 +0200 Subject: [PATCH] =?UTF-8?q?=E2=9C=A8=20Add=20option=20to=20generate=20unic?= =?UTF-8?q?ode=20values=20in=20`object`=20(#5010)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **Description** Recent bugs found in Vitest around badly formed snapshot names would have benefit from having a built-in way to switch on unicode generation on `object` and `anything`. The proposed PR adds a new flag onto them. It allows users to force generation of unicode strings as keys and values of the instances produced by these two helpers. The flag is called `withUnicodeString`. **Checklist** — _Don't delete this checklist and make sure you do the following before opening the PR_ - [x] The name of my PR follows [gitmoji](https://gitmoji.dev/) specification - [x] My PR references one of several related issues (if any) - [x] New features or breaking changes must come with an associated Issue or Discussion - [x] My PR does not add any new dependency without an associated Issue or Discussion - [x] My PR includes bumps details, please run `yarn bump` and flag the impacts properly - [x] My PR adds relevant tests and they would have failed without my PR (when applicable) **Advanced** - [x] Category: ✨ Introduce new features - [x] Impacts: N.A. --- .yarn/versions/62e8ed33.yml | 8 ++++++
