Global Variables

Global Variables

Enable the possibility to have global variables. Sometimes we need to access a variable from outside the scope, for example:

endpoints:
  - name: owner
    headers:
      Authorization: ${OWNER_TOKEN}
    requests:
      - name: register a book
        path: register/book
        method: post
        body:
          title: My Little Book
          author: John P.
        vars:
          book_id: ${{ request.json()["data"]["id"] }}
      - ...
      - ...
  - name: client
    headers:
      Authorization: ${CLIENT_TOKEN}
    requests:
      - name: rent a book
        path: rent/book/${book_id}
        method: POST
      - ...
      - ...

It would be nice to have a way to store book_id globally. Currently, the example above wouldn't work because the second request is not in the same scope as the first one.

Hi @camilamaia! Can I assign it to myself?

[camilamaia]

Hi.
It is already running?

I am trying:

endpoints:
  - name: Cliente Credentials
    path: https://cloud.ihf
    endpoints:
      - name: GET access_token
        requests:
          - name: credencial
            path: api/oauth/token
            method: POST
            headers: {
              'x-x-correlationID': xxxxxxx,
              'x-x-flowID': xxxxxxxxxx,
              'User-Agent': Apache-HttpClient/4.5.5 (Java/11.0.5),
              'Content-Type': application/x-www-form-urlencoded
            }
            body: "xxxxxxxxxxxx"
            vars:
              access_token: ${{ response.json()['access_token'] }}
            tests:
              - name: Status code = 200
                assert: ${{ response.status_code == 200 }}

  - name: Titular
    path: https://mbi.cloud.ihf
    endpoints:
      - name: GET access_token
        requests:
          - name: credencial
            path: seguranca/v1
            method: POST
            headers: {
              'x-x-correlationID': xxxxxxxxxxxxx,
              'x-x-flowid': xxxxxxxxxxx,
              'x-x-apikey': xxxxxxxxxxxxxxxxx,
              'Authorization': ${access_token},
              'Content-Type': application/json
            }
            tests:
              - name: credencial status code = 200
                assert: ${{ response.status_code == 200 }}

@BrunoPontesLira not yet. There is a PR opened for it, but we did not merge it: #328. We need to test it first and ensure it works properly.

[camilamaia]

Actually, the PR #328 does not solve it, my bad. It only makes it possible to create vars at endpoint level. This is still an open issue

I'd like to work on this issue, but since it's a non-simple change I'd like to discuss if you already have an intended approach to solve this problem. I was reading through the yaml specification and it says keys don't have a specific order. Considering that, we couldn't just run request nodes without ordering them. The way I'm thinking to approach the issue is building a dependency graph of request nodes, and we execute nodes without dependencies or with solved dependencies.

What are your thoughts?
