Provide an environment value to implement BDD test with a mocked cybersource service #133

I want to implement BDD test on my implementation of Psp Integration.

Usually, I have a mean to tell that the PSP API url point to a Wiremock managed url to send back to my code a controlled answer.

I cannot do that with cybersource SDK and ends up having to really use the test environnement ('CAS'). It means that my test MUST use keys and certificates that will expire, and that they will break at a later time. And it also means that my test are flawed, as I cannot control for sure the content of the answers from cybersource.

⇒ I would like another environment, e.g. called 'MOCK', that would allow a configuration value to store the effective url to use, e.g. 'https://localost:4000/mock/cybs', to be able to implement correctly BDD tests.
