Frequently Asked Questions

What is “Contract First”?

Qontract requires you to author the contract first which is then leveraged to run Provider Stubs and Contract Tests.

More on this here.

Does Qontract work with all programming languages?

Yes, Qontract can work with any language / tech stack in command line mode. Example: Refer this section where we run Qontract test on a Ruby Sinatra application.

At the moment programmatic support is only available to JVM languages. We are working on adding support for more languages and VMs.

How much code do I have to write to get Qontract running?

Zero, if you are adopting the command_line approach. If you need IDE support, you have to write a few lines of code to get it going.
