Code generation

[sagikazarmark]

Is your feature request related to a problem? Please describe.
I've used a number of different gherkin based BDD frameworks in the past and code generation was always a killer feature.

Even if it only meant dumping missing steps to the console, it was always a huge help.

Describe the solution you'd like
I think there are several things we could do here:

• godog just dumps the missing steps (with regex) to the console, which is nice.
• We could generate a default file (features_test.go ?) with the same (probably a bit more) content (if it doesn't already exist)
• probably more?

Additional context
I wouldn't say this should have the highest priority, especially compared to the required work vs benefit, but it's worth talking about.

This would also require a CLI tool.

That's definitely something I was planning to add but cannot do that as long as the API isn't stable.
I like what godog does here - the user has to only copy + paste the code and fill the gaps.

About generating any files - it will be more difficult because we'll have to give some options to use like change file/directory and the package's name etc. Dumping missing steps sounds great to me :)

I think this is a duplication of #15.

Yeah, they cover similar points. We can merge the two issues.
