At a glance

Run the full CI test suite (make testci), parse output, and report pass/fail with failure details.

  • Works in 5 steps: Run test suite → Parse results → Report → …
  • Post-build verification
  • Calls make
  • Tasks that involve Test generation

What it does

Regression Test Runner is an agent skill from aztfmod/terraform-provider-azurecaf. Run the full CI test suite (make testci), parse output, and report pass/fail with failure details. Use after code changes to verify nothing is broken. Triggers on: code changes, PR validation, post-build verification.

Its SKILL.md is about 310 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Test generation. The repository describes itself as: Terraform provider for the Terraform platform engineering for Azure. The licence is MIT.

When your agent uses it

  • Post-build verification
  • Tasks that involve Test generation

Example prompts

  • “/regression-test-runner”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Run test suite
  2. Parse results
  3. Report
  4. Coverage check
  5. Cleanup

What it can do on your machine

Read from SKILL.md and the folder at commit ac74615. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • make

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Regression Test Runner loads about 312 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 70 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~312

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Regression Test Runner

Procedure

1. Run test suite
bash
make test_ci 2>&1 | tee /tmp/test-ci-output.txt

This runs: unit tests, coverage, resource validation, and matrix testing.

2. Parse results

Check exit code:

  • 0: All tests passed
  • Non-zero: Failures detected

Extract summary from output:

bash
grep -E "^(ok|FAIL|---)" /tmp/test-ci-output.txt
3. Report

If all tests pass:

✅ Regression tests: PASSED
   Packages: <count> passed
   Coverage: <percentage>%

If failures detected:

❌ Regression tests: FAILED
   Failed packages:
   - <package>: <failure summary>
   
   Failure details:
   <relevant test output>

Extract the specific test function names and error messages for each failure.

4. Coverage check

Extract coverage percentage:

bash
grep "coverage:" /tmp/test-ci-output.txt | tail -1

Flag if coverage drops below 95%.

5. Cleanup
bash
rm -f /tmp/test-ci-output.txt
