Swift Testing run summary not captured — "in N suites" segment breaks the run-completion regex

[mickeyl]

What's the uncaptured output?

Swift Testing's final run-summary line is no longer captured. Recent Swift toolchains emit a in <N> suites segment that the current regex does not allow, so the whole tally is silently dropped:

􁁛  Test run with 76 tests in 17 suites passed after 0.020 seconds.

The only summary that survives is the unrelated (and misleading) empty XCTest bundle line:

Test Suite 'All tests' passed at 2026-06-25 12:06:30.599.
	 Executed 0 tests, with 0 failures (0 unexpected) in 0.000 (0.001) seconds

For a package that uses Swift Testing exclusively, the rendered output therefore reports Executed 0 tests and never shows the real 76 tests passed tally.

Suggested Regex

SwiftTestingRunCompletionCaptureGroup (CaptureGroups.swift:1961):

^[^ ] +Test run with (\d+) test(?:s)?(?: in \d+ suites?)? passed after ([\d.]+) seconds\.$

SwiftTestingRunFailedCaptureGroup (CaptureGroups.swift:1982) — the failure line carries the same in <N> suites segment and needs the matching change:

^[^ ] +Test run with (\d+) test(?:s)?(?: in \d+ suites?)? failed after ([\d.]+) seconds with (\d+) issue[s]?\.$

The (?: in \d+ suites?)? group is optional so both the older (Test run with N tests passed) and current (Test run with N tests in M suites passed) formats keep matching.

Suggested Output

Test run with 76 tests in 17 suites passed after 0.020 seconds

Additional Context

• Reproduced with swift test 2>&1 | xcbeautify -qq on a Swift Testing–only package.
• xcbeautify 3.2.1 (latest release); the same regex is still present on main at the time of filing.
• Both the passing and failing capture groups are affected; the per-suite (Suite X passed) lines and Test run started. are captured correctly — only the final run-completion summary is lost.
