An environment is required. This cannot be run in a mono-repo root, it can only be run for mono-repo sub-packages or a top-level singular package. Pass --footprint to record which functions each test file actually ran, as raw v8 coverage in node_modules/.cache/virmator/footprints. Tests still run normally, coverage is not calculated. This cannot be combined with the coverage command, which needs the same v8 output. - Examples - Run tests in a browser: `virmator test web` - Record what each test ran: `virmator test node --footprint` - Run tests in Node: `virmator test node` - Deps - [@augment-vir/test](https://npmjs.com/package/@augment-vir/test) - [@augment-vir/assert](https://npmjs.com/package/@augment-vir/assert) - Sub Commands - **web** Runs web tests in a browser using web-test-runner. - Examples - `virmator test web` - Configs - configs/web-test-runner.config.mjs - Deps - [@web/dev-server-esbuild](https://npmjs.com/package/@web/dev-server-esbuild) - [@web/test-runner-playwright](https://npmjs.com/package/@web/test-runner-playwright) - [@web/test-runner](https://npmjs.com/package/@web/test-runner) - [istanbul-smart-text-reporter](https://npmjs.com/package/istanbul-smart-text-reporter) - [typescript](https://npmjs.com/package/typescript) - Sub Commands - **coverage** Run tests and calculate code coverage. - Examples - `virmator test web coverage` - **update** Run tests and update snapshots. - Examples - `virmator test web update` - **node** Runs backend tests in Node.js using its built-in test runner. - Examples - `virmator test node` - Sub Commands - **coverage** Run tests and calculate code coverage. - Examples - `virmator test node coverage` - Configs - configs/c8.config.json - Deps - [c8](https://npmjs.com/package/c8) - [istanbul-smart-text-reporter](https://npmjs.com/package/istanbul-smart-text-reporter) - [@types/node](https://npmjs.com/package/@types/node) - **update** Run tests and update snapshots. - Examples - `virmator test node update` --- _Source: https://npm.io/package/@virmator/test · Machine-readable twin of the npm.io package page.
