How can pact handle dynamic bits in URL and query params ?

[mohanraj-r]

I am trying to test a complex interaction :

1. Issue a Get req against a specific path with a specific query parm - returns a result with a dynamic ref id
2. Subsequent Post req against a path composed of the dynamic ref id obtained in step 1 to get a dynamic value
3. Subsequent Get req against a static path with a query param constructed with the value obtained in step 2

How can I do this with Pact?

• Tried using dsl.Like - but looks like its supported only for body ?

Hi @mohanraj-r,

You are talking about functional testing, which is not something Pact supports. Each interaction must strictly be able to be validated in isolation from another. To achieve this, we use "provider states".

See https://docs.pact.io/best_practices/contract_tests_not_functional_tests.html for a discussion of these functional tests.

If I have misunderstood, and your request is more about being able to match the request path/headers/etc. using matchers, I've just come across a bug for that (related to a @gallamine query) and will release a fix in the next few days.

we use "provider states".

Thanks @mefellows
Can you give me an example of how to setup provider states in Go?
Looked at Provider States · Pact - but the examples are in Ruby - not clear how I can do the same in Go.

more about being able to match the request path/headers/etc. using matchers

Yes, having the ability to use matchers in the req URL, query etc could be helpful for me in this case as well

[mefellows]

Have you looked at the examples? The mux example shows how to achieve this with the in-built http package.

The readme also explains this in the provider section.

Hope that helps.
