The problem isn't really that the domain experts or business people aren't interested in reviewing these tests. The problem is that the cucumber language is just very, very poorly suited for writing anything beyond very basic specifications.

In practice when people try to use it for anything semi-complex they inevitably end up either writing very vague tests or repetitive tests, neither of which are of much interest to stakeholders.

I've used docs generated from hitchstory for having conversations with stakeholders. I've also shared semi-human readable unit and e2e tests - especially when it's, say, JSON snippets in an API with technical stakeholders.

Unfortunately, except for a few domains where specs can be expressed very concisely, cucumber isn't suitable for that.
