+## Describe the solution you'd like + +Redesign AIUnitTest as **AIUnitTest v2**, a **tool-first test execution layer for coding agents**. + +The v2 product should: + +1. Select a target from coverage, diff, or explicit user input. +2. Build a focused context package from source code, tests, config, and recent failures. +3. Call an external reasoning backend such as Copilot CLI or Gemini CLI. +4. Receive a structured plan and patch candidate. +5. Apply the patch in a controlled workspace. +6. Run validators such as pytest, syntax checks, and optional coverage comparison. +7. Retry with feedback when validation fails. +8. Return a final patch and execution report. + +This makes AIUnitTest responsible for orchestration, targeting, validation, guardrails, +and reporting, while delegating heavy reasoning to the best available backend. + +The product direction is to become the specialized testing layer that works with coding agents, +instead of competing with them as a general-purpose agent. + +## Describe alternatives you've considered + +### 1.

Added Copilot CLI backend for generating Python unit tests. - Added Gemini CLI backend for generating Python unit tests. - Implemented CLI commands for running tests, reporting, and backend management. - Created context builder for assembling context from source and test files. - Defined models for run requests, patch candidates, and validation results. - Developed orchestrator to manage the test generation workflow. - Implemented patch application with rollback capabilities. - Added reporting functionality with terminal and JSON renderers. - Established validation framework with syntax and pytest validators. - Introduced targeting strategies for selecting files to test. - Summarized validation feedback for improved retry logic. --- src/ai_unit_test/v2/__init__.py | 35 ++++- src/ai_unit_test/v2/backends/__init__.py | 8 + src/ai_unit_test/v2/backends/copilot_cli.py | 139 +++++++++++++++++ src/ai_unit_test/v2/backends/gemini_cli.py | 137 +++++++++++++++++ src/ai_unit_test/v2/cli.py | 148 ++++++++++++++++++ src/ai_unit_test/v2/context/__init__.py | 1 + src/ai_unit_test/v2/context/builder.py | 78 ++++++++++ src/ai_unit_test/v2/models.py | 30 ++++ src/ai_unit_test/v2/orchestrator.py | 159 ++++++++++++++++---- src/ai_unit_test/v2/patching/__init__.py | 1 + src/ai_unit_test/v2/patching/workspace.py | 133 ++++++++++++++++ src/ai_unit_test/v2/reporting/__init__.py | 1 + src/ai_unit_test/v2/reporting/renderer.py | 52 +++++++ src/ai_unit_test/v2/reporting/store.py | 103 +++++++++++++ src/ai_unit_test/v2/targeting/__init__.py | 1 + src/ai_unit_test/v2/targeting/selectors.py | 31 ++++ src/ai_unit_test/v2/validation/__init__.py | 1 + src/ai_unit_test/v2/validation/feedback.py | 33 ++++ src/ai_unit_test/v2/validation/runners.py | 147 ++++++++++++++++++ 19 files changed, 1208 insertions(+), 30 deletions(-) create mode 100644 src/ai_unit_test/v2/backends/__init__.py create mode 100644 src/ai_unit_test/v2/backends/copilot_cli.py create mode 100644 src/ai_unit_test/v2/backends/gemini_cli.py create mode 100644 src/ai_unit_test/v2/cli.py create mode 100644 src/ai_unit_test/v2/context/__init__.py create mode 100644 src/ai_unit_test/v2/context/builder.py create mode 100644 src/ai_unit_test/v2/patching/__init__.py create mode 100644 src/ai_unit_test/v2/patching/workspace.py create mode 100644 src/ai_unit_test/v2/reporting/__init__.py create mode 100644 src/ai_unit_test/v2/reporting/renderer.py create mode 100644 src/ai_unit_test/v2/reporting/store.py create mode 100644 src/ai_unit_test/v2/targeting/__init__.py create mode 100644 src/ai_unit_test/v2/targeting/selectors.py create mode 100644 src/ai_unit_test/v2/validation/__init__.py create mode 100644 src/ai_unit_test/v2/validation/feedback.py create mode 100644 src/ai_unit_test/v2/validation/runners.py diff --git a/src/ai_unit_test/v2/__init__.py b/src/ai_unit_test/v2/__init__.py index 544766c..b7a9e2a 100644 --- a/src/ai_unit_test/v2/__init__.py +++ b/src/ai_unit_test/v2/__init__.py @@ -1,13 +1,42 @@ -"""AIUnitTest v2 incubation package.""" +"""AIUnitTest v2 — tool-first test execution layer for coding agents.""" -from ai_unit_test.v2.models import ContextBundle, PatchCandidate, RunReport, TargetSpec, ValidationResult +from ai_unit_test.v2.context.builder import ContextBuilder, FileContextBuilder +from ai_unit_test.v2.models import ( + ContextBundle, + PatchApplication, + PatchCandidate, + RunReport, + RunRequest, + TargetSpec, + ValidationResult, +) from ai_unit_test.v2.orchestrator import V2Orchestrator +from ai_unit_test.v2.patching.workspace import PatchApplier +from ai_unit_test.v2.reporting.renderer import JsonRenderer, TerminalRenderer +from ai_unit_test.v2.reporting.store import RunStore +from ai_unit_test.v2.targeting.selectors import ExplicitFileSelector, TargetSelector +from ai_unit_test.v2.validation.feedback import FeedbackSummarizer +from ai_unit_test.v2.validation.runners import PytestValidator, SyntaxValidator, Validator __all__ = [ + "ContextBuilder", "ContextBundle", + "ExplicitFileSelector", + "FeedbackSummarizer", + "FileContextBuilder", + "JsonRenderer", + "PatchApplication", + "PatchApplier", "PatchCandidate", + "PytestValidator", "RunReport", + "RunRequest", + "RunStore", + "SyntaxValidator", + "TargetSelector", "TargetSpec", -

Date: Mon, 13 Apr 2026 10:40:25 -0300 Subject: [PATCH 05/12] Add unit tests for v2 components - Created test modules for various components in the v2 package, including backends, context, patching, reporting, targeting, and validation. - Implemented tests for core models such as RunRequest, TargetSpec, ContextBundle, PatchCandidate, PatchApplication, and ValidationResult. - Developed tests for the V2Orchestrator to ensure proper functionality and error handling. - Added CLI command tests to verify the behavior of the v2 CLI interface. --- tests/unit/v2/__init__.py | 1 +

Coverage: 83.44% (threshold: 70%). pre-commit run --all-files passes cleanly.
