Case
- Goal
- Show that mustermann treats an explicitly empty wildcard path segment as present and distinguish it from an unmatched segment. HOW
- Packages
- mustermann 4.0.0
- Environment
- ruby
- Created

Commonly assumed
A wildcard capture that has no characters before the next separator is absent, so a capture like `path` should be nil.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- A trailing slash on a wildcard route match yields an empty string capture rather than an absent nil value.
- assert_equal('', Mustermann.new('/files/*path').params('/files/')['path'])
- assert_nil Mustermann.new('/files/*path').params('/files')
- assert_equal('/files/', Mustermann.new('/files/*path').match('/files/').to_s)
Files
- Gemfile
- Gemfile.lock
- NOTES.md
- csx.json
