Offline, I made a suggestion that we scope this flag more narrowly, to only apply to one feature (singular instead of plural) and accept the name of that feature as an argument. The problem with having a single, catch-all “enable all the experimental features” flag is the next time someone adds some new experimental thing, if someone was already passing the flag then they will break.

Now that this has changed to be a singular, rather than plural, setting, I think the value should be an Array of String to allow for more than one experimental testing feature flag to be passed. I don't recall how exactly you do that using ArgumentParser but I believe there's a way.

For example, to allow someone to pass
--enable-experimental-testing-feature FeatureA --enable-experimental-testing-feature FeatureB 
| When this is set to merge, we'll need to regenerate the CLI docs for swift test that we recently added. Happy to do that, since it's a bit of messy process right now. Just wanted to call it out. /cc @bripeticca |

Add command line flag to enable experimental features
Motivation:
In order to support experimental features in Swift Testing we need a cli flag to enable them.
Modifications:
Added a command line flag called
enable-experimental-testing-featurewhich can be used to enable specific Swift Testing experimental features.--enable-experimental-testing-feature <FeatureName>Result:
Users will be able to specify the
enable-experimental-testing-featureflag when running tests in the CLI to enable specific experimental Swift Testing features.
