Upgrading Jest from v28 to v29? This guide aims to help refactoring your configuration and tests.
:::info
See changelog for the full list of changes.
:::
The supported Node versions are 14.15, 16.10, 18.0 and above.
As announced in the Jest 28 blog post, Jets 29 has changed the default snapshot formatting to {escapeString: false, printBasicPrototype: false}.
If you want to keep the old behavior, you can set the snapshotFormat property to:
+ snapshotFormat: {
+ escapeString: true,
+ printBasicPrototype: true
+ }jest-environment-jsdom has upgraded jsdom from v19 to v20. Due to issues with @types/jsdom, if you extend this environment, you might run into type errors. See DefinitelyTyped/DefinitelyTyped#60999 (reply in thread).
