Add support for tags

[nap-sam-dean]

Both Feature tags and Scenario tags

Any update/timeline on this?

[nap-sam-dean]

Honestly, it's not looking good. Without the ability to pass in tags somehow on the command line I can't see how this would work.

A change to xcodebuild to allow an environment variable (i.e. TAGS=@smoke,@api xcodebuild ...) to be set was my initial thought, but I can't see a way to pass that into the app's process.

I've not given up yet, but I'm not far off.

Worth adding a help-wanted label?

[nap-sam-dean]

Added. Didn't know that was a Thing™.

Have you considered using the Objective-C Gherkin parser/compiler?

I assume the difficulty here is in the use of tags to run only a subset of tests at a time.

Tags can also be used in conjunction with hooks to define @Before and @After blocks for scenarios. I assume that this would be an easier task.

Is this correct, and would it be worth splitting this issue in to these two scenarios?

[smaljaar]

@dhoskins we are currently looking into integrating support for the @after blocks so we can do cleanup after executing a test case, so hopefully a pull request will follow soon. If any ideas let me know!
Update: I got @before and @after tags working as they do for Cucumber, see https://github.com/smaljaar/XCTest-Gherkin/tree/feature/support-before-and-after-tags I hope to shape this into a pull request next week.

UPDATE: priority for this in our team was dropped, so no progress here for now. Maybe in future.

Hey Guys,
There is a Cucumberish library: https://github.com/Ahmed-Ali/Cucumberish / https://github.com/Shashikant86/XCFit that supports tags maybe worth looking at it and apply solutions to XCTest-Gherkin?

[depoon]

Was a huge fan of XCTest-Gherkin when i first saw it... but i've migrated over to Cucumberish

[bartzet]

@depoon what was the main reason you have chosen Cucumberish over XCTest-Gherkin?

[kerrmarin]

Thanks for the pointers @bartzet -- we'd be happy to look at a pull request that implements tags as this seems like a widely requested feature.

@depoon I'd also be super keen to learn why you migrated over :)

It is possible to pass flag from xcodebuild using User-Defined Build settings.
This answer explains how it can be accessed at runtime:
https://stackoverflow.com/questions/3968919/how-can-i-access-a-user-defined-xcode-build-setting

I think, app needs to be rebuild for this value to be reflected, which then means that test-without-building might not work. But this is probably not an issue for majority of use cases.

I made a PR for scenario tags. It will help others to bypass some scenarios in a feature file.
with having tags for scenario even if there are no tags for the feature it could help a lot.
