  • 0.18.0
    • Features:
      • Allows calling PropCheck::Property#check without a block, which will just return self. This is useful for writing wrapper functions that use before/after/around/with_config etc hooks which might themselves optionally want a block so they can be chained. (See the forall_with_db snippet in the README for an example)
  • 0.17.0
    • Features:
      • Recursive generation using PropCheck::Generators.tree.
  • 0.16.0
    • Features:
      • New option in PropCheck::Property::Configuration to resize all generators at once.
      • Wrapper functions to modify this easily in PropCheck::Property called #resize, #grow_fast, #grow_slowly, #grow_exponentially, #grow_quadratically, #grow_logarithmically.
  • 0.15.0
    • Features:
      • Generators for Date, Time and DateTime.
        • Basic work done by @Haniyya. Thank you very much!
        • Extra functions to generate dates/times/datetimes in the future or the past.
        • Allow overriding the epoch that is used.
        • A new option in PropCheck::Property::Configuration to set the default epoch.
      • Generator to generate Sets.
      • New builtin float generators (positive, negative, nonzero, nonnegative, nonpositive). Both in 'normal' flavor and in 'real' flavor (that will never generate infinity or other special values).
      • PropCheck::Generator#with_config which enables the possibility to inspect and act on the current PropCheck::Property::Configuration while generating values.
    • Fixes:
      • Preserve backwards compatibility with Ruby 2.5 by not using infinite ranges internally (c.f. #8, thank you, @hlaf!)
      • Make a flaky test deterministic by fixing the RNG. (c.f. #9, thank you, @hlaf!)
      • Fix a crash when using a hash where not all keys are symbols. (c.f. #7, thank you, @Haniyya!)
      • Fix situations in which PropCheck::Generators.array would for certain config values never generate empty arrays.
  • 0.14.1 - Swap awesome_print for amazing_print which is a fork of the former that is actively maintained.
  • 0.14.0 - Adds uniq: true option to Generators.array. Makes PropCheck::Property an immutable object that returns copies that have changes whenever reconfiguring, allowing re-usable configuration.
  • 0.13.0 - Adds Generator#resize
  • 0.12.1 - Fixes shrinking when filtering bug.
  • 0.12.0 - PropCheck::Generators#instance
  • 0.11.0 - Improved syntax to support Ruby 2.7 and up without deprecation warnings, full support for #where.
  • 0.10.0 - Some bugfixes, support for #where
  • 0.8.0 - New syntax that is more explicit, passng generated values to blocks as parameters.
