Advanced tools
The CCK - aka. Cucumber Compatibility Kit - is a set of features and Messages. It aims to validate an implementation of the Cucumber Messages protocol.
The kit is composed of features and messages:
.ndjson files - are the reference: a given feature
from the kit, executed using its dedicated step definitions, must emit the
corresponding MessagesAfter running npm install --save-dev @cucumber/compatibility-kit, the kit is
available in your node_modules in node_modules/@cucumber/compatibility-kit/features.
You will find there some folders. Each folder owns a feature with its corresponding Messages.
You can execute the features with your implementation. For example with cucumber, it would look like the following:
npx cucumber-js node_modules/@cucumber/compatibility-kit/features/**/*.feature
Here's we have been able to run our features. However it did not find the step definitions. It is up to you to implement your step definitions compatible with your own tool.
In order to make some experiments, the kit comes with step definitions compatible with
fake-cucumber and written using TypeScript.
You will find also a few assets which may be required for some features. For example,
the attachments feature is using an asset cucumber.png to test the possibility
to attach images to the Messages.
Each feature available in the kit comes with a .ndjson. That file is the expected
Messages related the execution of the corresopnding feature. For convenience, the
messages are serialized using the ndjson format.
The idea is to execute the features of the kit using your tool, to generate the corresponding messages, and to compare your messages with the ones from the kit.
The Cucumber Compatibility Kit is part of the development tools of Cucumber. It allows us to make sure that all our implementations are properly supporting our internal protocol and thus are compabitle with each other and with our common tools like the html-formatter.
It can be a valuable tool if you are developing integration with cucumber, or your own implementation of it.

You can also take a look on cucumber-js to see how the kit is used there.
