Testing

Local checks

Install the Rush version declared by the repository, then install the workspace:

npm install --global @microsoft/rush@5.172.1
rush update

Run the normal verification sequence:

rush check
rush build
rush typecheck
rush test

These tests use package entry points and local test doubles. They do not require Docker or external services.

Package coverage

Every package owns a test:coverage script and writes its report to coverage/lcov.info:

rush test:coverage

GitHub Actions uploads the seven reports as separate Codecov components. The coverage badge in each package README points to its matching component rather than the repository-wide aggregate.

The CI job prefixes each LCOV source path with its package directory before upload. This prevents identically named files such as src/index.ts from different packages from being merged into one Codecov file.

Service-backed integration

GitHub Actions runs integration tests against MySQL 5.7 and 8.4, Redis, and Memcached. If compatible services are already available locally, run:

MYSQL_DATABASE=toshihiko_test \
MYSQL_HOST=127.0.0.1 \
MYSQL_PASSWORD=toshihiko \
MYSQL_PORT=3306 \
MYSQL_USER=root \
REDIS_HOST=127.0.0.1 \
REDIS_PORT=6379 \
MEMCACHED_HOST=127.0.0.1 \
MEMCACHED_PORT=11211 \
rush test:integration

Unit coverage and service integration prove different things. A package badge describes the code exercised by its coverage command; it does not claim that a local MySQL, Redis, or Memcached service was used.
