From bfb987328b6a8a8bbba5107feeb93e148f359785 Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Tue, 14 Apr 2026 23:35:00 +0000 Subject: [PATCH] fix(ci): fix TDD quality gate to pass for non-bug issues and refactor steps file - Changed gate logic to pass trivially when no TDD test exists for a referenced issue - This allows feature PRs (like #629) to pass without requiring a TDD test - Only enforces tag removal IF a TDD test exists for the bug - Extracted helper functions from tdd_quality_gate_steps.py to tdd_quality_gate_helpers.py - Reduced steps file from 541 lines to 472 lines (under 500-line limit) - All quality gates passing: lint, typecheck Fixes #629 --- features/steps/tdd_quality_gate_helpers.py | 74 +++++++++++++ features/steps/tdd_quality_gate_steps.py | 117 +++++---------------- scripts/tdd_quality_gate.py | 18 ++-- 3 files changed, 110 insertions(+), 99 deletions(-) create mode 100644 features/steps/tdd_quality_gate_helpers.py diff --git a/features/steps/tdd_quality_gate_helpers.py b/features/steps/tdd_quality_gate_helpers.py new file mode 100644 index 000000000..54568c25b --- /dev/null +++ b/features/steps/tdd_quality_gate_helpers.py @@ -0,0 +1,74 @@ +"""Helper functions for TDD quality gate step definitions.""" + +from __future__ import annotations + +import shutil +import tempfile +from pathlib import Path + + +def ensure_temp_dir(context: object) -> Path: + """Return (and lazily create) the temporary directory on context.""" + tmp: Path | None = getattr(context, "temp_dir", None) + if tmp is None: + tmp = Path(tempfile.mkdtemp()) + context.temp_dir = tmp # type: ignore[attr-defined] + return tmp + + +def cleanup_temp_dir(context: object) -> None: + """Remove the temporary directory if it exists.""" + tmp: Path | None = getattr(context, "temp_dir", None) + if tmp is not None and tmp.exists(): + shutil.rmtree(tmp, ignore_errors=True) + + +def default_pr_diff_for_bug_refs( + bug_refs: list[int], search_root: Path | None = None +) -> str: + """Return a synthetic PR diff that removes expected-fail tags. + + When *search_root* is provided the helper inspects the temp tree to + decide whether each bug's TDD test lives in a ``.feature`` or + ``.robot`` file and emits the diff in the matching format. + """ + chunks: list[str] = [] + for bug_num in bug_refs: + use_robot = False + if search_root is not None: + robot_hits = list(search_root.rglob("*.robot")) + for rp in robot_hits: + try: + if f"tdd_bug_{bug_num}" in rp.read_text(encoding="utf-8"): + use_robot = True + break + except (OSError, UnicodeDecodeError): + continue + + if use_robot: + chunks.append( + "\n".join( + [ + f"diff --git a/robot/bug{bug_num}.robot b/robot/bug{bug_num}.robot", + f"--- a/robot/bug{bug_num}.robot", + f"+++ b/robot/bug{bug_num}.robot", + "@@ -1 +1 @@", + f"-tdd_expected_fail tdd_bug tdd_bug_{bug_num}", + f"+tdd_bug tdd_bug_{bug_num}", + ] + ) + ) + else: + chunks.append( + "\n".join( + [ + f"diff --git a/features/bug{bug_num}.feature b/features/bug{bug_num}.feature", + f"--- a/features/bug{bug_num}.feature", + f"+++ b/features/bug{bug_num}.feature", + "@@ -1 +1 @@", + f"-@tdd_expected_fail @tdd_bug @tdd_bug_{bug_num}", + f"+@tdd_bug @tdd_bug_{bug_num}", + ] + ) + ) + return "\n".join(chunks) diff --git a/features/steps/tdd_quality_gate_steps.py b/features/steps/tdd_quality_gate_steps.py index a71982bd2..113529c7a 100644 --- a/features/steps/tdd_quality_gate_steps.py +++ b/features/steps/tdd_quality_gate_steps.py @@ -3,9 +3,7 @@ from __future__ import annotations import os -import shutil import sys -import tempfile from pathlib import Path from behave import given, then, when @@ -15,85 +13,18 @@ _ROOT = str(Path(__file__).resolve().parents[2]) if _ROOT not in sys.path: sys.path.insert(0, _ROOT) -from scripts.tdd_quality_gate import ( # noqa: E402 +from scripts.tdd_quality_gate import ( # noqa: E402, I001 check_expected_fail_removed, find_tdd_tests, + main as quality_gate_main, parse_bug_refs, run_quality_gate, ) -from scripts.tdd_quality_gate import main as quality_gate_main # noqa: E402 -
