Just 28 から数カ月後しか経っていませんが、Jest 29 がリリースされ ました。 Jest 28 ブログ記事で説明したように、アップグレードをできるだけスムーズなものにするために、このバージョンには破壊的変更がいくつか含まれています。
Jest joins OpenJS Foundation
Today we're excited to announce that Jest is joining the OpenJS Foundation!
This change transfers ownership of the project from Meta to the Jest Core team via the OpenJS Foundation as an Impact Project. We’re grateful to Meta for creating Jest and all of their support over the years, and we look forward to the future of Jest as a project owned by the Jest community!
Check out the Meta Engineering blog and OpenJS Foundation blog announcements for more info.
Jest 28: Shedding weight and improving compatibility 🫶
Jest 28 is finally here, and it comes with some long requested features such as support for sharding a test run across multiple machines, package exports
and the ability to customize the behavior of fake timers. These are just some personal highlights, and we'll be highlighting more in this blog post.
Additionally, as announced in the Jest 27 blog post last year, we have removed some packages that no longer are used by default from the default installation. As a result the installation size has dropped by about 1/3.
