• [Bug]: TIA marks a source edit made during a run as tested, so no later run selects it

  pestphp/pest#1972 · Filter by author keithyeohh opened on Oct 15, 2026

• [Bug]: TIA filters --list-tests, so tools that count tests see none

  pestphp/pest#1971 · Filter by author keithyeohh opened on Oct 15, 2026

• [Bug]: TIA locally() ignores CI detection, and some baseline fetch failures exit 1, unlike the TIA docs

  pestphp/pest#1970 · Filter by author keithyeohh opened on Oct 15, 2026

• [Bug]: --tia --coverage keeps the cached coverage of deleted tests, so --min passes on a real coverage drop

  pestphp/pest#1957 · Filter by author almontasser opened on Oct 10, 2026

• [Bug]: --tia --coverage keeps the old line numbers of an edited file in coverage.bin.gz, so uncovered lines stay after a revert

  pestphp/pest#1954 · Filter by author almontasser opened on Oct 10, 2026

• [Bug]: --tia --coverage never records a new dependency of a test that is already in the graph, so a broken dependency replays as passed

  pestphp/pest#1953 · Filter by author almontasser opened on Oct 10, 2026

• Mutation testing: --filter built from all covering tests exceeds the OS argument limit (posix_spawn() failed: Argument list too long)

  pestphp/pest#1952 · Filter by author Armandola89 opened on Oct 9, 2026

• [Bug]: --mutate hides unreadable files, so mutants behind a failed read can never be killed

  pestphp/pest#1949 · Filter by author yeapea opened on Oct 7, 2026

• [Bug]: Arch tests parse the same file once per namespace and keep every copy in memory

• [pest-plugin-browser] Timed-out initialize corrupts every later browser test

  pestphp/pest#1938 · Filter by author joseburgon opened on Sep 29, 2026

• [Bug]: --mutate counts mutants as killed when the mutant subprocess never runs a test (false 100 % score): paratest options leak into it; on Windows the executable is wrong too
