v0.4.0

This release includes basic ground required to actually start use this library for any test suite.

Features:

• expect().to ... syntax by default with option to enable should on Object.
• no global scope pollution with Spec2.describe + option to enable global describe DSL.
• describe, context, it DSL for defining examples and example groups.
• before and after hooks to be executed before and after each example in current and nested example groups.
• let, let!, subject and subject! for defining example-group-scoped bindings.
• minimal necessary list of builtin matchers (matches stdlib's spec list).
• random order execution.
• color and no-color output.
• minimal and documentation reporters.
• ability to configure almost every piece of library by using custom runner, order, reporter and/or output.
• ability to register your own matchers.

List of implemented builtin matchers:

• eq("hello, world") - asserts actual is equal to expected
• raise_error(ErrorClass [, message_matcher]) - checks if block raises expected error
• be(42) - asserts actual is the same as expected
• match(/hello .+/) - asserts actual is matching provided regexp
• be_true - asserts actual is equal true
• be_false - asserts actual is equal false
• be_truthy - asserts actual is not nil or false
• be_falsey - asserts actual is nil or false
• be_nil - asserts actual is equal nil
• be_close(42, 0.01) - asserts actual is in delta-proximity of expected
• expect(42).to_be < 45 - asserts arbitrary method call on actual to be truthy
• be_a(String) - asserts actual to be of expected type (uses is_a?)
