bats-testing-patterns SKILL.md skillA
This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.
bats-testing-patterns from rudycity/superagent is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add rudycity/superagent/bats-testing-patterns@git:20260626.019dba9Pins git:20260626.019dba9 in mdr.lock. Pin the fingerprint instead.

Master Bash Automated Testing System (Bats) for comprehensive shell script testing. Use when writing tests for shell scripts, CI/CD pipelines, or requiring test-driven development of shell utilities.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Bats Testing Patterns
Comprehensive guidance for writing comprehensive unit tests for shell scripts using Bats (Bash Automated Testing System), including test patterns, fixtures, and best practices for production-grade shell testing.
## When to Use This Skill
- Writing unit tests for shell scripts
- Implementing test-driven development (TDD) for scripts
- Setting up automated testing in CI/CD pipelines
- Testing edge cases and error conditions
- Validating behavior across different shell environments
- Building maintainable test suites for scripts
- Creating fixtures for complex test scenarios
- Testing multiple shell dialects (bash, sh, dash)
## Detailed patterns and worked examples
Detailed pattern documentation lives in `references/details.md`. Read that file when the navigation tier above is insufficient.
## Testing Error Conditions
```bash
#!/usr/bin/env bats
@test "Function fails with missing file" {
run my_function "/nonexistent/file.txt"
[ "$status" -ne 0 ]
[[ "$output" == *"not found"* ]]
}
@test "Function fails with invalid input" {
run my_function ""
[ "$status" -ne 0 ]
}
@test "Function fails with permission denied" {

How to install
mdr add rudycity/superagent/bats-testing-patterns@sha256:d7992dbf589789f1The line at the top of this page pins the label git:20260626.019dba9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
