fledge-plugin-coverage

Run test coverage for the project and (optionally) fail the build if it drops below a threshold. Auto-detects the language and shells out to the right tool.

Built in Rust. Uses the fledge-v1 plugin protocol with the exec capability so the language tool runs through fledge's sandboxed exec rather than directly.

Install

fledge plugins install CorvidLabs/fledge-plugin-coverage

You'll be prompted to grant the exec capability.

Usage

fledge coverage                          # detect language, run coverage, print %
fledge coverage --threshold 80           # gate: exit 1 if coverage < 80%
fledge coverage --lang python            # force language detection
fledge coverage --json                   # machine-readable

Detection

If the wrong tool is picked (e.g. you use vitest, not jest), pass --lang or wrap your tool in a fledge task and call that instead.

Use in lanes

[lanes.coverage-gate]
description = "Block if coverage drops below 80%"
steps = [{ run = "fledge coverage --threshold 80" }]

[lanes.ci]
steps = [
  { parallel = ["fmt", "lint"] },
  { run = "fledge coverage --threshold 80" },
  "build",
]

JSON output

{
  "schema_version": 1,
  "action": "coverage",
  "language": "rust",
  "command": "cargo llvm-cov --summary-only --workspace",
  "exit_code": 0,
  "coverage_percent": 87.4,
  "threshold": 80.0,
  "gate_failed": false,
  "ok": true
}

ok is true when: the tool exited 0, coverage was extracted, and the threshold (if any) was met.

Exit codes

Build

A pre-built binary ships at bin/fledge-coverage. If cargo is on PATH at install time, the build hook recompiles from source for the host platform.
