What is jest-snapshot?

The jest-snapshot package is a part of the Jest testing framework. It allows developers to capture snapshots of values, typically React component trees, and compare them to previously recorded snapshots to detect changes. This is useful for ensuring that UI does not change unexpectedly.

What are jest-snapshot's main functionalities?

Snapshot Testing

This feature allows you to create a snapshot of a value, which will be saved to a file. On subsequent test runs, the saved snapshot is compared to the current value, and any differences will cause the test to fail. This is useful for testing the output of components.

expect(value).toMatchSnapshot();

Inline Snapshots

Inline snapshots work similarly to regular snapshots, but instead of saving the snapshot to a separate file, it is embedded directly in the test file. This can be more convenient for smaller snapshots or when you want to keep the test and its expected output closely tied together.

expect(value).toMatchInlineSnapshot();

Snapshot Property Matchers

Snapshot property matchers allow you to ignore certain properties within a snapshot by using matchers from Jest's expect API. This is useful when you want to ignore dynamic values that change between test runs, such as timestamps or generated IDs.

expect(value).toMatchSnapshot({ createdAt: expect.any(Date) });
