Suggest using inline snapshots (prefer-inline-snapshots)

In order to make snapshot tests more managable and reviewable toMatchInlineSnapshot() and toThrowErrorMatchingInlineSnapshot should be used to write the snapshots inline in the test file.

Rule details

This rule triggers a warning if toMatchSnapshot() or toThrowErrorMatchingSnapshot is used to capture a snapshot.

The following pattern is considered warning:

expect(obj).toMatchSnapshot();

expect(error).toThrowErrorMatchingSnapshot();

The following pattern is not warning:

expect(obj).toMatchInlineSnapshot();

expect(error).toThrowErrorMatchingInlineSnapshot();
