coverage 7.15 uses the sysmon core by default on Python 3.14+, which does not support dynamic contexts. The resulting CoverageWarning becomes an error through filterwarnings, so every test fails on 3.14 and 3.15. Remove --cov-context=test, and the html.show_contexts option that only had an effect together with it. Assisted-by: ClaudeCode:claude-opus-5

All tests fail on Python 3.14 and 3.15 on
main. coverage 7.15 uses the sysmon core by default on 3.14+, and that core does not support dynamic contexts. Each test triggersCoverageWarning: Dynamic contexts aren't supported with core=sysmon, whichfilterwarnings = ["error"]turns into an error — 812 errors per run.This removes
--cov-context=test, and thehtml.show_contextsoption that only had an effect together with it.Reproduced with
coverage==7.15.3on 3.14 (812 errors), and confirmed the removal makes the suite pass.Note: the
