[0.2.0] - 2026-03-08

Added

• Igniter Mix tasks — 8 generators for common architecture patterns:
  • mix igniter.install arch_test / mix arch_test.install — basic arch test file with cycle check
  • mix arch_test.gen.phoenix — opinionated Phoenix setup (layers + naming + conventions)
  • mix arch_test.gen.layers — classic web → context → repo layered architecture
  • mix arch_test.gen.onion — onion / hexagonal architecture (domain → application → adapters → web)
  • mix arch_test.gen.modulith — bounded-context slice isolation
  • mix arch_test.gen.naming — naming convention rules (no Managers, schema placement)
  • mix arch_test.gen.conventions — code hygiene checks (no IO.puts, dbg, bare raise)
  • mix arch_test.gen.freeze — freeze baseline for gradual adoption
• Optional Igniter dependency — {:igniter, "~> 0.7", only: [:dev, :test], optional: true, runtime: false}

[0.1.2] - 2026-03-07

Added

• Modulith.all_modules_covered_by/3 — asserts that every module under a namespace pattern belongs to a declared slice. Modules that escape slice coverage cause an explicit test failure instead of being silently ignored. Supports :except (list of glob patterns) and :graph (for testability). Also delegated from ArchTest as all_modules_covered_by/2,3.

[0.1.1] - 2026-03-07

Fixed

• OTP version compatibility: tests now use stable fixture modules instead of OTP-version-sensitive stdlib internals, fixing failures on OTP 26/27
• All credo --strict issues resolved (implicit try, Enum.map_join, negated if/else, nesting depth, cyclomatic complexity)

[0.1.0] - 2026-03-06

Initial release.

Added

• Dependency assertions — should_not_depend_on/2, should_only_depend_on/2, should_not_be_called_by/2, should_only_be_called_by/2, should_not_transitively_depend_on/2, should_be_free_of_cycles/1, should_not_exist/1
• Naming assertions — should_reside_under/2, should_have_name_matching/2, should_have_module_count/2
• Behaviour / protocol assertions — should_implement_behaviour/2, should_not_implement_behaviour/2, should_implement_protocol/2, should_not_implement_protocol/2
• Module attribute assertions — should_have_attribute/2, should_not_have_attribute/2, should_have_attribute_value/3, should_not_have_attribute_value/3
• Function assertions — should_export/3, should_not_export/3, should_have_public_functions_matching/2, should_not_have_public_functions_matching/2, should_use/2, should_not_use/2
• Layered architecture — define_layers/1 + enforce_direction/1, define_onion/1 + enforce_onion_rules/1
• Modulith / bounded-context isolation — define_slices/1, allow_dependency/3, enforce_isolation/1, should_not_depend_on_each_other/1
• ArchTest.Conventions — pre-built checks: no_io_puts_in/2, no_process_sleep_in/2, no_application_get_env_in/2, no_dbg_in/2, no_raise_string_in/2, no_plug_in/2, all_public_functions_documented/2
• ArchTest.Metrics — afferent/efferent coupling, instability, abstractness, distance from main sequence (Martin metrics)
• ArchTest.Freeze — violation baseline freezing for gradual adoption; ARCH_TEST_UPDATE_FREEZE=true mode
• ArchTest.ModuleSet — fluent module selection DSL: glob patterns, excluding/2, union/2, intersection/2, satisfying/1
• ArchTest.Pattern — glob pattern compiler with * (single segment) and ** (multi-segment) wildcards
• ArchTest.Collector — BEAM-native dependency graph builder via OTP :xref; works on compiled bytecode, no source parsing
• Conventions support for both legacy and modern BEAM debug formats — handles both :abstract_code (OTP < 24) and :debug_info_v1 with :elixir_erl backend (Elixir 1.14+)
