Macro insta::assert_json_snapshot [−][src]
Asserts a Serialize
snapshot in JSON format.
This works exactly like assert_yaml_snapshot!
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:
assert_json_snapshot!(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 refer to the redactions feature in the guide.
The snapshot name is optional but can be provided as first argument.
