Changelog

v0.9.0 — 2026-05-25

Spec-tree runner with hooks, mocks, custom matchers, and parallel execution.

Added

• Documentation
  • mkdocs site under docs-src/, published to the gh-pages branch at https://gdonald.github.io/BDD-Behave/
  • Spec-driven doc extraction
• Core DSL
  • describe / it / specify with arbitrary nesting on a spec tree
  • before / after / around hooks, including metadata-keyed and inherited variants
  • let / let! (eager) / subject / is-expected one-liner syntax
  • Shared contexts and shared examples
  • Tags, focus, and skip
  • Example filtering by name or metadata
  • Pending examples, dry-run, and example listing
  • Run by file, directory, line number, or a single block
• Expectations
  • Custom and composable matcher DSL
  • Matchers for equality, comparison, be-between / be-within, boolean, nil, type checking, respond-to, have-attributes, include, all, sequence, match, string content, change / change-by / change-from-to, junctions, exceptions (raise-error with attribute matching), promises, supplies/channels, and eventually for async
  • aggregate_failures block plus auto-aggregation
• Mocks
  • Doubles, method stubbing, spies with call verification, and partial mocking
• Runner & CLI
  • Parallel execution with queue distribution, a discovery subprocess, per-shard retry on worker crash, and aggregated memory / profile / benchmark output
  • --fail-fast, --watch, --progress-total, retry, seed control, and bisect for flaky specs
  • Code coverage metrics, compatible with --parallel
• Formatters
  • Progress (default), TAP, JUnit, JSON, JsonEvents, HTML, Tree, and Documentation
• Diagnostics
  • Junction-aware, shape-detecting diffs
  • Timing profiling, memory profiling, and benchmarking with baselines
  • Time mocking
• Configuration
  • File-based configuration with CLI precedence

Changed

• Migrated files from Perl 6 file extensions to Raku throughout
• Reworked expectations to accept actual values
• Replaced the grammar-driven core with an in-memory spec tree (Suite → ExampleGroup → Example / Hook) walked by the runner
• Regrouped lib/, t/, and specs/ by feature area (core/, expectations/, parallel/, etc.)
• Default formatter is now Progress

v0.0.3 — 2019-09-14

Grammar-driven runner with a small DSL.

Added

• describe / context / it blocks with nesting
• let(:name) => { ... } with block-scoped overrides
• expect(x).to.be(y) equality matcher, with .to.not for negation
• Variable interpolation in expectations (expect(:foo).to.be(42), expect(42).to.be(:foo))
• CLI behave [path] runner; auto-discovers specs/*spec.p6 when no path is given
• Colorized output and failure reporting with file and line numbers
