Node.js module

node:test/reporters

The 'node:test/reporters' module provides built-in reporter formats for node:test, such as tap, json, and baseline. Reporters format test results for human or machine consumption.

Use reporters to integrate with CI systems, test dashboards, or custom logging pipelines.

const lcov: ReporterConstructorWrapper<typeof LcovReporter>
The lcov reporter outputs test coverage when used with the --experimental-test-coverage flag.
const spec: ReporterConstructorWrapper<typeof SpecReporter>
The spec reporter outputs the test results in a human-readable format.
function dot(
source: AsyncIterable<TestEvent>
): AsyncIterator<string>;
The dot reporter outputs the test results in a compact format, where each passing test is represented by a ., and each failing test is represented by a X.
function junit(
source: AsyncIterable<TestEvent>
): AsyncIterator<string>;
The junit reporter outputs test results in a jUnit XML format.
function tap(
source: AsyncIterable<TestEvent>
): AsyncIterator<string>;
The tap reporter outputs the test results in the TAP format.
