Pattern File

Diffy Server displays on the dashboard the endpoints that have been replayed.

If, for example, one of your endpoints is api/segments/{segmentName} then on Diffy's dashboard you will see something like:

api-segments-aSegment 0%
api-segments-anotherSegment 0%
api-segments-thisotherSegment 0%

To avoid this and group those calls, you can define pairs (regular-expressions, replacements), for example, an example of the content of PATTERN_FILE could be:

api/segmentChanges/[a-zA-Z][a-zA-Z0-9_-]*,api/segmentChanges/SEGMENT_NAME

In that case, then on the previous case all calls would be grouped in:

api/segmentChanges/SEGMENT_NAME

Another good example is:

[0-9a-f]{8}-[0-9a-f]{4}-[1-5][0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12},UUID

The example above can parse Universal Unique Identifiers and replace them with UUID.
