3.0.0.beta2 / 2014-02-17

full changelog

Breaking Changes for 3.0.0:

• Remove deprecated support for accessing the RSpec constant using
  Rspec or Spec. (Myron Marston)
• Remove deprecated RSpec::Expectations.differ=. (Myron Marston)
• Remove support for deprecated expect(...).should. (Myron Marston)
• Explicitly disallow expect { }.not_to change { } with by,
  by_at_least, by_at_most or to. These have never been supported
  but did not raise explicit errors. (Myron Marston)
• Provide === rather than == as an alias of matches? for
  all matchers. The semantics of === are closer to an RSpec
  matcher than ==. (Myron Marston)
• Remove deprecated RSpec::Matchers::OperatorMatcher constant.
  (Myron Marston)
• Make RSpec::Expectations::ExpectationNotMetError subclass
  Exception rather than StandardError so they can bypass
  a bare rescue in end-user code (e.g. when an expectation is
  set from within a rspec-mocks stub implementation). (Myron Marston)
• Remove Test::Unit and Minitest 4.x integration. (Myron Marston)

Enhancements:

• Simplify the failure message of the be matcher when matching against:
  true, false and nil. (Sam Phippen)
• Update matcher protocol and custom matcher DSL to better align
  with the newer expect syntax. If you want your matchers to
  maintain compatibility with multiple versions of RSpec, you can
  alias the new names to the old. (Myron Marston)
  • failure_message_for_should => failure_message
  • failure_message_for_should_not => failure_message_when_negated
  • match_for_should => match
  • match_for_should_not => match_when_negated
• Improve generated descriptions from change matcher. (Myron Marston)
• Add support for compound matcher expressions using and and or.
  Simply chain them off of any existing matcher to create an expression
  like expect(alphabet).to start_with("a").and end_with("z").
  (Eloy Espinaco)
• Add contain_exactly as a less ambiguous version of match_array.
  Note that it expects the expected array to be splatted as
  individual args: expect(array).to contain_exactly(1, 2) is
  the same as expect(array).to match_array([1, 2]). (Myron Marston)
• Update contain_exactly/match_array so that it can match against
  other non-array collections (such as a Set). (Myron Marston)
• Update built-in matchers so that they can accept matchers as arguments
  to allow you to compose matchers in arbitrary ways. (Myron Marston)
• Add RSpec::Matchers::Composable mixin that can be used to make
  a custom matcher composable as well. Note that custom matchers
  defined via RSpec::Matchers.define already have this. (Myron
  Marston)
• Define noun-phrase aliases for built-in matchers, which can be
  used when creating composed matcher expressions that read better
  and provide better failure messages. (Myron Marston)
• Add RSpec::Machers.alias_matcher so users can define their own
  matcher aliases. The description of the matcher will reflect the
  alternate matcher name. (Myron Marston)
• Add explicit be_between matcher. be_between has worked for a
  long time as a dynamic predicate matcher, but the failure message
  was suboptimal. The new matcher provides a much better failure
  message. (Erik Michaels-Ober)
• Enhance the be_between matcher to allow for inclusive or exclusive
  comparison (e.g. inclusive of min/max or exclusive of min/max).
  (Pedro Gimenez)
• Make failure message for not_to be #{operator} less confusing by
  only saying it's confusing when comparison operators are used.
  (Prathamesh Sonpatki)
• Improve failure message of eq matcher when Time or DateTime
  objects are used so that the full sub-second precision is included.
  (Thomas Holmes, Jeff Wallace)
• Add output matcher for expecting that a block outputs to_stdout
  or to_stderr. (Luca Pette, Matthias Günther)
• Forward a provided block on to the has_xyz? method call when
  the have_xyz matcher is used. (Damian Galarza)
• Provide integration with Minitest 5.x. Require
  rspec/expectations/minitest_integration after loading minitest
  to use rspec-expectations with minitest. (Myron Marston)

Bug Fixes:

• Fix wrong matcher descriptions with falsey expected value (yujinakayama)
• Fix expect { }.not_to change { }.from(x) so that the matcher only
  passes if the starting value is x. (Tyler Rick, Myron Marston)
• Fix hash diffing, so that it colorizes properly and doesn't consider trailing
  commas when performing the diff. (Jared Norman)
• Fix built-in matchers to fail normally rather than raising
  ArgumentError when given an object of the wrong type to match
  against, so that they work well in composite matcher expressions like
  expect([1.51, "foo"]).to include(a_string_matching(/foo/), a_value_within(0.1).of(1.5)).
  (Myron Marston)

Deprecations:

• Retain support for RSpec 2 matcher protocol (e.g. for matchers
  in 3rd party extension gems like shoulda), but it will print
  a deprecation warning. (Myron Marston)

full changelog

Deprecations:

• Deprecate chaining by, by_at_least, by_at_most or to off of
  expect { }.not_to change { }. The docs have always said these are
  not supported for the negative form but now they explicitly raise
  errors in RSpec 3. (Myron Marston)
• Change the semantics of expect { }.not_to change { x }.from(y).
  In RSpec 2.x, this expectation would only fail if x started with
  the value of y and changed. If it started with a different value
  and changed, it would pass. In RSpec 3, it will pass only if the
  value starts at y and it does not change. (Myron Marston)
• Deprecate matcher == value as an alias for matcher.matches?(value),
  in favor of matcher === value. (Myron Marston)
• Deprecate RSpec::Matchers::OperatorMatcher in favor of
  RSpec::Matchers::BuiltIn::OperatorMatcher. (Myron Marston)
• Deprecate auto-integration with Test::Unit and minitest.
  Instead, include RSpec::Matchers in the appropriate test case
  base class yourself. (Myron Marston)
• Deprecate treating #expected on a DSL-generated custom matcher
  as an array when only 1 argument is passed to the matcher method.
  In RSpec 3 it will be the single value in order to make diffs
  work properly. (Jon Rowe)

full changelog

Deprecations

• Deprecate have, have_at_least and have_at_most. You can continue using those
  matchers through https://github.com/rspec/rspec-collection_matchers, or
  you can rewrite your expectations with something like
  expect(your_object.size).to eq(num). (Hugo Baraúna)
• Deprecate be_xyz predicate matcher when xyz? is a private method.
  (Jon Rowe)
• Deprecate be_true/be_false in favour of be_truthy/be_falsey
  (for Ruby's conditional semantics) or be true/be false
  (for exact equality). (Sam Phippen)
• Deprecate calling helper methods from a custom matcher with the wrong
  scope. (Myron Marston)
  • def self.foo / extend Helper can be used to add macro methods
    (e.g. methods that call the custom matcher DSL methods), but should
    not be used to define helper methods called from within the DSL
    blocks.
  • def foo / include Helper is the opposite: it's for helper methods
    callable from within a DSL block, but not for defining macros.
  • RSpec 2.x allowed helper methods defined either way to be used for
    either purpose, but RSpec 3.0 will not.

3.0.0.beta1 / 2013-11-07

full changelog

Breaking Changes for 3.0.0:

• Remove explicit support for 1.8.6. (Jon Rowe)
• Remove the deprecated be_close matcher, preferring be_within instead.
  (Sam Phippen)
• Rename be_true and be_false to be_truthy and be_falsey. (Sam Phippen)
• Make expect { }.to_not raise_error(SomeSpecificClass, message),
  expect { }.to_not raise_error(SomeSpecificClass) and
  expect { }.to_not raise_error(message) invalid, since they are prone
  to hiding failures. Instead, use expect { }.to_not raise_error (with no
  args). (Sam Phippen)
• Within RSpec::Matchers.define blocks, helper methods made available
  either via def self.helper or extend HelperModule are no longer
  available to the match block (or any of the others). Instead
  include your helper module and define the helper method as an
  instance method. (Myron Marston)

Enhancements:

• Support do..end style block with raise_error matcher. (Yuji Nakayama)
• Rewrote custom matcher DSL to simplify its implementation and solve a
  few issues. (Myron Marston)
• Allow early return from within custom matcher DSL blocks. (Myron
  Marston)
• The custom matcher DSL's chain can now accept a block. (Myron
  Marston)
• Support setting an expectation on a raise_error matcher via a chained
  with_message method call. (Sam Phippen)

Bug Fixes:

• Allow include and match matchers to be used from within a
  DSL-defined custom matcher's match block. (Myron Marston)

Deprecations:

• Using the old :should syntax without explicitly configuring it is deprecated.
  It will continue to work but will emit a deprecation warning in RSpec 3 if
  you do not explicitly enable it. (Sam Phippen)

2.14.2 / 2013-08-14

full changelog

Bug fixes

• Fix be_<predicate> matcher to not support operator chaining like the
  be matcher does (e.g. be == 5). This led to some odd behaviors
  since be_<predicate> == anything returned a BeComparedTo matcher
  and was thus always truthy. This was a consequence of the implementation
  (e.g. subclassing the basic Be matcher) and was not intended behavior.
  (Myron Marston).
• Fix change matcher to compare using == in addition to ===. This
  is important for an expression like:
  expect {}.to change { a.class }.from(ClassA).to(ClassB) because
  SomeClass === SomeClass returns false. (Myron Marston)

Bug fixes

• Values that are not matchers use #inspect, rather than #description for
  documentation output (Andy Lindeman, Sam Phippen).
• Make expect(a).to be_within(x).percent_of(y) work with negative y
  (Katsuhiko Nishimra).
• Make the be_predicate matcher work as expected used with expect{...}.to change... (Sam Phippen).

2.14.0.rc1 / 2013-05-27

full changelog

Enhancements

• Enhance yield_control so that you can specify an exact or relative
  number of times: expect { }.to yield_control.exactly(3).times,
  expect { }.to yield_control.at_least(2).times, etc (Bartek
  Borkowski).
• Make the differ that is used when an expectation fails better handle arrays
  by splitting each element of the array onto its own line. (Sam Phippen)
• Accept duck-typed strings that respond to :to_str as expectation messages.
  (Toby Ovod-Everett)

Bug fixes

• Fix differ to not raise errors when dealing with differently-encoded
  strings (Jon Rowe).
• Fix expect(something).to be_within(x).percent_of(y) where x and y are both
  integers (Sam Phippen).
• Fix have matcher to handle the fact that on ruby 2.0,
  Enumerator#size may return nil (Kenta Murata).
• Fix expect { raise s }.to raise_error(s) where s is an error instance
  on ruby 2.0 (Sam Phippen).
• Fix expect(object).to raise_error passing. This now warns the user and
  fails the spec (tomykaira).

Deprecations

• Deprecate expect { }.not_to raise_error(SpecificErrorClass) or
  expect { }.not_to raise_error("some specific message"). Using
  these was prone to hiding failures as they would allow any other
  error to pass. (Sam Phippen and David Chelimsky)
