glacier test

Synopsis. Run the Go test suite with a live status panel and a color-coded aggregated summary.

Other commands: vibe version generate lint init new completions explain

Flags

Flag	Default	Description
[patterns]	./...	go/packages patterns to test.
--race	false	Forward -race to go test.
--cover	false	Forward -cover and write a profile to .glacier/coverage.out.
--fuzz		Forward -fuzz=<regexp> to go test.
--bench		Forward -bench=<regexp> and compare results against the baseline.
--baseline	.glacier/bench-baseline.json	Path to the benchmark baseline file.
--update-baseline	false	Write the current benchmark run as the new baseline.
--format	text	Output format. Values: text, junit, sarif, json.
--slowest	5	Number of slowest tests shown in the summary.
--no-status	false	Suppress the live status panel animation.

Examples

Run all tests:

glacier test

Run with the race detector and coverage:

glacier test --race --cover

Run only tests in one package:

glacier test ./cli/...

Run benchmarks and record a new baseline:

glacier test --bench=. --update-baseline

Run benchmarks and fail if any regress more than 5%:

glacier test --bench=.

Emit JUnit XML for CI:

glacier test --format=junit > results.xml

Run a fuzz target for 30 seconds:

glacier test --fuzz=FuzzParse ./conf/...

What it does under the hood

test launches go test -json as a subprocess and streams its output through a JSON event parser. In-flight packages are shown in a term.StatusBar (up to 10 rows) rendered by term.Animator. Completed packages stream to the terminal as they finish, colored by pass/fail/skip. When all packages finish, the command renders a summary box via term.Box showing package count, pass/fail/skip counts, coverage, wall time, the N slowest tests, and any failure output with an isolation hint. For --format=json, every raw go test -json event is forwarded verbatim, followed by a Glacier-specific aggregate object. For --bench, benchmark output is collected in a separate channel and compared against the stored baseline via cmd/glacier/internal/benchcmp; a regression over the threshold (default 5%) prints a box and exits 66.

Exit codes

Code	Meaning
0	All tests passed
2	Bad pattern or unknown format
66	One or more tests failed, or a benchmark regressed more than the threshold
70	go test failed to start
130	SIGINT
