Raise test coverage: utils.py, elastic.py, and opensearch.py to 100% (#816)
* Raise test coverage: utils, elastic, and opensearch to 100%
Coverage of the shipped library rises from 88% to 90%, with
parsedmarc/utils.py 86% -> 100% and elastic.py / opensearch.py
99% -> 100%. All new tests assert on observable behaviour and mock
only at SDK boundaries (dnspython Resolver.resolve, requests.get,
subprocess.check_call, elasticsearch_dsl/opensearchpy Document.save).
New tests cover: query_dns transient-error retries, the load_ip_db
download/cache/bundled fallback chain, the IPinfo API token probe and
per-request MMDB fallbacks, _normalize_ip_record schema handling,
reverse-DNS-map invalid-CSV fallback, caller-provided reverse DNS
maps, Outlook MSG conversion (missing msgconvert and success paths),
parse_email Cc/Bcc/attachment-hash branches, aggregate-XML edge cases
(bytes input, repeated policy_published, unknown RFC 9990 override
types, missing org_name, attribute-only <email>), extract_report on
non-seekable streams, and the _AggregateReportDoc.save() override
that derives passed_dmarc.
Bugs found by the new tests, fixed in the same PR per the testing
standards:
- parse_email() crashed with KeyError: 'Headers' on messages whose
From header is present but unparseable (e.g. a bare "From:" line):
the fallback read parsed_email["Headers"], but the parsed headers
are stored under lowercase "headers" (assigned a few lines up in
the same function), so the key never exists. At the CLI surface
this made any failure report whose embedded sample had an empty
From: header fail to parse ("Missing value: 'Headers'").
- configure_ipinfo_api(probe=True) logged "IPinfo API configured"
when the probe could not reach the API, contradicting its own
docstring ("other errors are logged and the token is still
accepted"): _ipinfo_api_lookup() returns None on network errors
instead of raising, so the probe's exception handler was
unreachable. The probe now checks the lookup result and warns on
failure; 401/403 still raises InvalidIPinfoAPIKey.
Dead code deleted rather than padded with tests:
- _SMTPTLSReportDoc.add_policy() in elastic.py and opensearch.py
(the save paths construct _SMTPTLSPolicyDoc directly).
- The no-op "for failure_index in failure_indexes: pass" loop in
both migrate_indexes() implementations (parameter still accepted).
- The importlib.resources ImportError fallback in utils.py, which
re-imported the same module and is unreachable on Python >= 3.10.
- The "Invalid report content" guard in extract_report(): every
input branch assigns file_object or raises first (confirmed by
pyright narrowing with the guard removed).
Also widens parse_aggregate_report_xml's annotation to str | bytes
to match its existing runtime behaviour (bytes are decoded with
errors ignored).

* Use assertGreater for the reverse-DNS-map fallback size check
Addresses the github-code-quality bot finding on PR #816: assertTrue
with a comparison inside can't show the operands on failure, while
assertGreater reports both values and the failed relation. No change
to test behavior.

Fix failure-report timestamp skew on non-UTC hosts in ES/OpenSearch/Splunk outputs (#812)
* Fix failure-report timestamp skew on non-UTC hosts in ES/OS/Splunk sinks arrival_date_utc is a UTC wall-clock string (generated in parse_failure_report via an aware-UTC strftime), but elastic.py, opensearch.py, and splunk.py parsed it back into a naive datetime and called .timestamp(), which per the Python docs interprets naive values as local time (https://docs.python.org/3/library/datetime.html#datetime.datetime.timestamp). On any non-UTC host the epoch stored as the ES/OpenSearch arrival_date field, used in the failure-report dedup match query, and sent as the Splunk HEC event time was therefore off by the host's UTC offset (verified -3600 s under TZ=Europe/Warsaw in January). Add an assume_utc keyword to human_timestamp_to_datetime() / human_timestamp_to_unix_timestamp() that attaches timezone.utc to naive parses, and use it at the three arrival_date_utc call sites. Aware inputs (explicit offsets) are unaffected; all other callers keep the existing local-time semantics, whose round-trip with timestamp_to_human is self-consistent on a single host (the broader local-time output question is tracked separately in issue #811 bug 2). The three new sink regression tests fail on the unfixed code (verified by stashing the source changes) and force TZ=Europe/Warsaw via time.tzset() so they catch the skew even on UTC CI runners. Fixes half of https://github.com/domainaware/parsedmarc/issues/811. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Deduplicate TZ-forcing test boilerplate; fix unix-timestamp docstring Extract the repeated TZ=Europe/Warsaw + time.tzset() setup/cleanup from the four timestamp regression tests into a shared tests/tzutil.py force_tz() helper, and correct human_timestamp_to_unix_timestamp()'s docstring, which said the return type was float while the function returns int.

test: cover no-display-name Reply-To header flattening (#786)
The 10.0.3 Reply-To header flattening (elastic.py / opensearch.py line 711)
has two branches: display-name present ("Name <addr>") and absent (bare
address). The existing test only exercised the former, leaving the
empty-display-name branch uncovered — the two lines Codecov flagged on the
10.0.3 patch. Add a failure report whose Reply-To has no display name and
assert sample.headers["reply-to"] flattens to the bare address.

Land 10.0.3 changes on master (#785)
PR #784 was stacked on the #783 branch and its base was never retargeted to master, so it merged into fix/mailsuite-2.2.1-empty-address instead of master. master therefore has 10.0.2 (#783's squash) but is missing the 10.0.3 changes. This re-lands exactly that delta — the Reply-To/Delivered-To parser fix, the ES/OS Reply-To header flattening, and the Splunk/OpenSearch/Grafana failure dashboard fixes, with the version bumped to 10.0.3. No mailsuite re-bump (the >=2.2.1 floor is already on master from 10.0.2). Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

Expand honest test coverage from 59% to 83%; fix two latent bugs (#775)
* Expand honest test coverage from 59% to 83%; fix two latent bugs 271 new tests across the output modules, ES/OS clients, CLI config parsing, and the top-level parsing surface. Coverage measured against shipped code only (see [tool.coverage.run] source = ["parsedmarc"] omit = ["*/parsedmarc/resources/maps/*.py"] in pyproject.toml). Per-module results: s3.py 38% → 100% (also fixes SMTP-TLS-to-S3 bug below) gelf.py 40% → 100% syslog.py 46% → 100% kafkaclient.py 34% → 100% splunk.py 24% → 100% loganalytics.py 56% → 100% webhook.py 78% → 100% (also removes redundant try/except) elastic.py 36% → 99% opensearch.py 40% → 99% cli.py 52% → 69% __init__.py 74% → 76% (also fixes append_json bug below) utils.py 84% (unchanged in this PR) TOTAL 59% → 83% The remaining 17% is honest. The biggest unreached blocks are _main() in cli.py and the watch-mode mailbox iteration in __init__.py, both of which would require either standing up live subsystems (real Elasticsearch, real IMAP) or mocking deep enough that the test would verify the mock rather than the code. The PR-A AGENTS.md guidance — "if 90% requires faking it, ship 85% honestly" — applies here. Bugs fixed while writing tests: 1. parsedmarc/s3.py — SMTP-TLS-to-S3 was completely broken. save_report_to_s3 unconditionally read report["report_metadata"] when building S3 object metadata, but RFC 8460 §4.3 SMTP TLS reports are flat (no report_metadata sub-object). The CLI's surrounding try/except silently swallowed the KeyError, so every SMTP-TLS report quietly failed to upload. Also fixes a related issue: parse_smtp_tls_report_json stores begin_date as the raw ISO-8601 string from the report (per the SMTPTLSReport TypedDict and RFC 8460 §4.3), but the S3 code path assumed a datetime with .year / .month / .day attributes. Both fixed; the broken metadata-extraction branch now uses the flat-report fields, and the date branch normalizes via human_timestamp_to_datetime. 2. parsedmarc/__init__.py — append_json corrupted JSON output files on the second write. The original implementation opened files in "a+" mode, then seek()ed backwards to overwrite the trailing "]" with ",\n" before appending more elements. Python's docs are explicit (https://docs.python.org/3/library/functions.html#open): on POSIX, writes in "a"/"a+" mode always go to EOF regardless of seek() position. The result was that the second call produced [...]\n],\n[...] -style corrupted output instead of a single merged array. Replaced with a read-merge-write pattern: load the existing array (if any), append the new elements, rewrite the whole file. The CSV cousin append_csv was not affected — it doesn't seek backwards. 3. parsedmarc/webhook.py — removed redundant try/except blocks in save_aggregate_report_to_webhook / save_failure_report_to_webhook / save_smtp_tls_report_to_webhook. _send_to_webhook already catches every Exception itself, so the outer except blocks were unreachable dead code (covered nothing, defended against nothing, and inflated the source-line count without testing value). Testing approach: mocks at SDK boundaries (boto3 resource, kafka producer, requests session, opensearch/elasticsearch Document/Search, azure LogsIngestionClient). Tests verify the parsedmarc-side transformation logic — document/event construction, index/topic naming, dedup queries, error wrapping — rather than asserting on mock invocations as a proxy for behaviour. Where a branch is defensive against a caller that doesn't exist in the codebase, the test is omitted (commented in code rather than hidden behind a pragma). 547 tests total (was 276), all passing. ruff check + format clean. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Document the two bug fixes from this PR in the 10.0.0 changelog Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Document testing standards in AGENTS.md Adds a "Testing standards" section covering the principles applied in PR-A (split) and PR-B (coverage expansion): - Coverage measures shipped code only — don't reintroduce tests/* to the scope, don't expand omit, don't use # pragma: no cover. - Honest tests assert on observable behaviour, not "the mock was called". Mock at SDK boundaries; parse the payload that gets sent. - "If 90% requires faking it, ship 85% honestly" — coverage is a tool, not a goal. PR-B's deliberate stops at cli.py 69% and __init__.py 76% are the documented precedent for when to halt. - Verify bug claims against the relevant RFC, internal types, installed SDK source, or upstream docs before changing code. Cite the source in the commit message and test docstring (RFC 8460 §4.3 and the Python open() docs for #775's two bug fixes are the pattern to follow). - Bugs found while writing tests are fixed in the same PR; the test doubles as the regression guard. - File layout (tests/test_<module>.py) is non-negotiable; module-level test loggers need fresh-handler setup so test ordering doesn't break assertLogs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Cover the corrupt-file fallback in append_json Codecov flagged 2 missing patch-coverage lines on PR #775: the except (json.JSONDecodeError, OSError) branch in append_json, which falls back to overwriting when the existing file isn't a parseable JSON array. Two new tests in tests/test_init.py:TestAppendJson exercise both paths: - test_corrupt_existing_file_is_overwritten_cleanly: existing file contains invalid JSON; append_json overwrites with the new array. - test_existing_file_with_non_list_root_is_overwritten: existing file parses as {"foo": ...} (dict, not list); the isinstance guard rejects it and we overwrite cleanly. Patch coverage now 100% on the bug fix. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
