Order the nodes in a wave

Use this procedure when independent nodes must run in a specified sequence. For example, a delete must not run before a search that needs the data.

Procedure

1. Give a positive priority to the node that must run first:

   ---
   id: create
   priority: 1
   ---
   POST {{base_url}}/notes
   { "title": "score" }
   HTTP 201

2. Give no priority to the node in the middle. The default value is 0.

   ---
   id: search
   ---
   GET {{base_url}}/notes?q=score
   HTTP 200
   [Asserts]
   jsonpath "$.items" count > 0

3. Give a negative priority to the node that must run last:

   ---
   id: delete
   priority: -1
   ---
   DELETE {{base_url}}/notes/score
   HTTP 204

4. Examine the plan:

   hurl-orchestra --dry-run ./tests

Result

The three nodes are in the same wave. hurl-orchestra runs the priority groups in sequence: create, then search, then delete.

TIP

Use priority only for nodes that do not share data. If a node needs the output of a different node, use deps.
