Score: 10/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 5362, "days_push": 2532, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, archived
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Bats is a TAP-compliant testing framework for Bash scripts and UNIX programs, where test cases are Bash functions with special @test syntax. It runs tests in isolation and outputs human-readable or machine-parsable TAP results suitable for CI systems.

## Use cases
- test bash scripts
- write unit tests for shell scripts
- verify unix programs behave as expected
- run shell tests in continuous integration
- assert command exit status and output
- tap-compliant test output for ci pipelines

## When to avoid
- you need a general-purpose testing framework for non-shell languages
- you need advanced features like parallel test execution or mocking found in newer forks like bats-core
