Chutney v3.6.0 has a new linter to detect inconsistent use of quotes in your Cucumber Gherkin.

I was reading someone's Gherkin feature files the other day and came across something like this:

Feature: My exciting feature
  Scenario: My beautiful scenario
    Given I have 'something'
    When I do an "action"
    Then a wonderful thing will happen

Nothing terribly abnormal, but just for a moment I had to think: why is something single quoted and action double quoted? Is there a difference? Is there something meaningful in the quoting style? There isn't, but is does look weird. So Chutney now has a linter to detect if a feature file mixes the two styles.

It also copes nicely with possessive apostrophes, both singular and plural (which was a trickier regex than I expected it to be).

Scenario: Possessions
  Given the user has a thing
  When the user's 'thing' is quoted
  Then all users' 'things' are fine

In this example, thing and things are detected, the apostrophes for user are ignored.

It will also cope with possession inside a quoted string, and embedded quotes.

Scenario: Quoted possessions
  Given the user has a thing
  When this 'user's thing' is quoted
  Then the "'user'" is happy

In the above, user's thing and 'user' are detected as the quoted entity.
