PACT vs spring cloud contract tests

问题

I am trying to understand the better tool between PACT and Spring Cloud Contract to implement Consumer Driver Contract Tests. I dont find any clear examples to find the pros and cons.

I want to implement CDCT, and I dont use Spring in my project. From what i understood I am assuming PACT is good to go with.

Any information or suggestions are welcomed. Thank you.

Spring Cloud Contract allows you to define and test contracts for both REST APIs and messaging. It provides a clear and easy to use statically typed Groovy DSL and also allows for defining contracts via yaml. Both with the DSL and with yaml, defining contracts is very intuitive to anyone familiar with the standard HTTP/messaging terms, for example:

request {
    method PUT()
    url '/fraudcheck'
    body([
           "client.id": $(regex('[0-9]{10}')),
           loanAmount: 99999
    ])
    headers {
        contentType('application/json')
    }
}
response {
    status OK()
    body([
           fraudCheckStatus: "FRAUD",
           "rejection.reason": "Amount too high"
    ])
    headers {
        contentType applicationJson()
    }
}

The producer-side tests are automatically generated by SCC and added to the project during build. If a correct implementation fulfilling the contracts is not in place, the project will not be built and deployed. If they pass, the stubs for consumer will be generated and published along with the corresponding artifact version.

On the consumer side, for HTTP, SCC provides the Stubrunner, that launches a Wiremock (in-memory http server) instance, that provides stubbed responses to matching requests. Stubrunner works with external artifact repositories such as Nexus and Artifactory and also with local m2 repositories.

SCC integrates with SpringBoot seamlessly and also integrates with Spring Cloud out of the box and can be used in place of service discovery during integration tests.

It also integrates out of the box with Pact and allows to leverage additional Pact features via hooks while using only the SCC contracts definitions.

SCC also provides a Docker-based option for implementing and testing contracts in technologies other than JVM.
