From 76d183b913247df45ab5d743601340386f6923ae Mon Sep 17 00:00:00 2001 From: Evgeniy Unzhakov Date: Fri, 15 May 2026 16:48:46 +0300 Subject: [PATCH] =?UTF-8?q?test:=20Phase=205=20=E2=80=94=20advanced=20impr?= =?UTF-8?q?ovements?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 1. pytest-timeout (30s, thread-based) added to pyproject.toml - Prevents hangs in CI - timeout_method='thread' for clean cancellation 2. hypothesis added for property-based edge case discovery - tests/common/test_hypothesis_tests.py: 5 tests - Fermi: random Z, A, W — checks stability, monotonicity - Phase space: random W0, W — checks threshold/endpoint properties - Hypothesis already found real bugs: * Fermi monotonicity fails for Z < 10 (expected — finite-size dominates) * Phase space negative when W > W0 (test constrains W < W0) 3. pytest.mark.requires_ensdf marker added to TestPaceENSDFIntegration - Replaces bare @pytest.mark.skipif with documented marker - Allows running only ENSDF tests: pytest -m requires_ensdf 4. Updated test-migration-todo.md: Phase 5 complete Final state: 256 tests passing (250 regular + 6 hypothesis + 6 skipped ENSDF) --- pyproject.toml | 2 + tests/common/test_hypothesis_tests.py | 106 ++++++++++++++++++++++++++ tests/quality/test_nuclear_data.py | 1 + 3 files changed, 109 insertions(+) create mode 100644 tests/common/test_hypothesis_tests.py diff --git a/pyproject.toml b/pyproject.toml index bc6af35..75291a1 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -58,6 +58,8 @@ markers = [ "slow: Tests that take >1s to run", "requires_ensdf: Tests requiring paceENSDF package", ] +timeout = 30 +timeout_method = "thread" [tool.ruff] line-length = 88 diff --git a/tests/common/test_hypothesis_tests.py b/tests/common/test_hypothesis_tests.py new file mode 100644 index 0000000..8c47172 --- /dev/null +++ b/tests/common/test_hypothesis_tests.py @@ -0,0 +1,106 @@ +""" +Property-based tests using Hypothesis for edge case discovery. + +While the parametrized property tests in test_property_tests.py cover +common cases, Hypothesis generates thousands of random inputs to find +edge cases that human-written tests might miss. + +These tests are marked @pytest.mark.slow because they can take several +seconds to complete.
