Fix invalid escape sequence warnings in test_macros.py - #744
Merged
Conversation
Regex patterns embedded in expected test strings used a bare \. inside regular (non-raw) triple-quoted strings, which Python 3.12 flags as SyntaxWarning: invalid escape sequence '\.'. Escape the backslash properly (\\.) so the literal string value is unchanged but the warning is eliminated. CI test runs were emitting eight of these warnings per occurrence (4 occurrences x parallel workers), cluttering the pytest output.
