Changelog

v0.9.4 — 2026-07-15

Added

• A precompile pass before parallel discovery, building every spec file's module precompilation in one --compile-only subprocess so a single process writes the whole dependency graph and discovery and the workers only read it

• Recovery from a cache left inconsistent by earlier runs: a precompile pass that dies clears the project's reported .precomp directories and rebuilds

• --no-precompile to skip the precompile pass

• --compile-only to load the given spec files, writing their precompilation, and exit without running examples or printing

Fixed

• A worker or the discovery subprocess killed by a signal such as SIGSEGV no longer reads as exit 0 and "0 examples" success. Signal deaths fold to the 128+N convention across the lpt, queue, isolated, and serial worker paths and fail the run with a message naming the signal

v0.9.3 — 2026-07-10

Fixed

• Parallel discovery no longer hangs when a spec file fails to load in a worker

• Failure reasons now reach the JSON formatter, so parallel runs report full failure detail instead of an empty failure record

• JSON event attributes emit in a stable order

• Stray non-object lines in a worker's JSON stream are no longer treated as valid events

• Temporary paths are created before workers write to them

• Mocked time no longer drifts backward between reads

v0.9.2 — 2026-06-24

Added

• Live coverage progress line when filtering the raw log on a terminal, with a percent, a bar, and a rough ETA

• Fallback content on a coverage HTML file page when the source is unavailable

Changed

• Coverage now defaults to the lighter MVM_COVERAGE_CONTROL=0 line-hit mode; pass --coverage-counts for the heavier per-line execution counts

Fixed

• Environment variable propagation to parallel workers

v0.9.1 — 2026-06-01

Added

• Bareword slang for let, so blocks can reference fixtures as owner in addition to :owner

• raise and throw aliases for the raise-error exception matcher

• --version flag on the behave CLI

Removed

• Per-example memory profiling.

Fixed

• Parallel worker distribution and a require failure under --parallel

• Line number rendering in spec failure output

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
