Asserts a Serialize snapshot in JSON format.

This works exactly like assert_serialized_snapshot_matches but serializes in JSON format. This is normally not recommended because it makes diffs less reliable, but it can be useful for certain specialized situations.

Example:

ⓘThis example is not tested
assert_json_snapshot_matches!("snapshot_name", vec[1, 2, 3]);

The third argument to the macro can be an object expression for redaction. It's in the form { selector => replacement }. For more information about redactions see redactions.

Additionally the name is optional. For more information see unnamed snapshots
