# Makefile for chime.el test suite
# Usage:
#   make test              - Run all tests
#   make test-file FILE=overdue - Run tests in one file
#   make test-one TEST=name     - Run one specific test
#   make test-unit         - Run unit tests only
#   make test-integration  - Run integration tests only
#   make clean             - Remove byte-compiled files
