VersionedPactUrlLoader does not seem to support use of Auth

[gleithall]

I have been trying to create tests to be run when the contract_requiring_verification_published event is published by the Pact Broker.

I believe I need to create tests that receive information about the specific Pact to be verified, probably the Pact URL.

The PactUrl annotation seems to require a hardcoded URL, which won't work for this use case, so I have been looking at the VersionedPactUrl annotation.

From my experiments, and looking at the code, it seems that the auth value provided to the VersionedPactUrl annotation gets ignored by the VersionedPactUrlLoader.

In particular I have tried debugging

• I can see the auth value on the VersionedPactUrl passed here:

  pact-jvm/provider/src/main/kotlin/au/com/dius/pact/provider/junitsupport/loader/VersionedPactUrlLoader.kt

  Line 10 in 4752365

  constructor(pactUrl: VersionedPactUrl) : this(pactUrl.urls) {}

• When the VersionedPactUrlLoader calls the PactUrlLoader, it does not provide a value for the authentication argument: compare

  pact-jvm/provider/src/main/kotlin/au/com/dius/pact/provider/junitsupport/loader/VersionedPactUrlLoader.kt

  Line 9 in 4752365

  open class VersionedPactUrlLoader(urls: Array<String>) : PactUrlLoader(expandVariables(urls)) {

  with

  pact-jvm/provider/src/main/kotlin/au/com/dius/pact/provider/junitsupport/loader/PactUrlLoader.kt

  Line 16 in 4752365

  open class PactUrlLoader(val urls: Array<String>, val authentication: Auth? = null) : PactLoader {

I notice that this code was written nearly four years, so I wonder

• have I misunderstood how this is supposed to work?
• is there another way that people achieve the goal of handling the contract_requiring_verification_published event?

VersionedPactUrlLoader was for a specific use, where you have a static URL and just need to replace a version in the URL each time.

The proper way to do it is add @AllowOverridePactUrl to your test, then set the pact.filter.pacturl JVM property or environment variable with the URL from the webhook call. That property will need to be set on the test JVM, not the build tool JVM.

Thank you for answering this question, @rholshausen. This makes a lot of sense, so I think this issue can be closed.
