coverage — Coverage Threshold Gate

Parses a coverage report and fails with exit code 1 if total line coverage is below the specified minimum. Shows a per-file breakdown of files below the threshold.

Two formats are supported and auto-detected:

Format	Extension	Used by
LCOV	.info or no extension	Rust (cargo-llvm-cov), Jest, pytest-cov, Go
Cobertura XML	.xml	Python (coverage.py), Java (JaCoCo), .NET

Usage

greengate coverage [OPTIONS]

Options:
  -f, --file <FILE>    Path to the coverage file [default: coverage/lcov.info]
  -m, --min <MIN>      Minimum coverage threshold % [default: 80]
  -h, --help           Print help

Examples

# LCOV (Rust, Jest, pytest, Go)
greengate coverage --file coverage/lcov.info --min 80

# Cobertura XML (Python coverage.py, JaCoCo)
greengate coverage --file coverage.xml --min 80

# Stricter 90% gate
greengate coverage --file coverage/lcov.info --min 90

# Use defaults from .greengate.toml
greengate coverage

Generating coverage reports

# Rust (cargo-llvm-cov)
cargo llvm-cov --lcov --output-path coverage/lcov.info

# Jest
jest --coverage --coverageReporters=lcov

# pytest
pytest --cov=. --cov-report=lcov:coverage/lcov.info
pytest --cov=. --cov-report=xml:coverage.xml

# Go
go test ./... -coverprofile=coverage/lcov.info

Sample output

ℹ️  Analyzing coverage file: coverage/lcov.info (threshold: 80.0%)
