• Fixes for crystal 0.18.*

• Add type annotations, where new compiler would require them
• Fix minor type anomalies, that have popped up as instance/class vars got annotated

• Makes after { ... } and delayed { ... } hooks to run even in case of assertion failure.

This patch release makes elapsed time functionality available for usage in custom reporters as ::Spec2::ElapsedTime. Additionally, it fixes the problem with elapsed time, when test suite takes more than one hour.

This minor release adds elapsed time output for standard reporters.

This minor release adds new DSL component delayed { ... }. It is used inside of it ".." { ... } block and its block will be executed after test example execution and after all after { ... } hooks execution. Hence the name: Delayed.

This minor release changes all exposed abstract interfaces to use composition instead of inheritance.

This patch release re-implements existing DSL to match up breaking changes from compiler version upgrade.

This patch release fixes bug with abstract signatures of Reporter class, that were discovered upon upgrading version of Crystal. See #20 and #21

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?)
