Node.js Built-in Test Reporter
JSON →node-test-reporter is an opinionated, actively maintained test reporter for Node.js's built-in test runner, providing a clean, Ava-inspired output experience. Its current stable version is 1.2.0, with minor releases frequently addressing bugs and adding small features. It differentiates itself by offering enhanced error formatting for `equal` and `strictEqual` assertions via `concordance`, improved stack trace reporting, and an early error display mechanism for tests that hang due to unclosed resources. The reporter also integrates with Node.js's experimental code coverage features and provides a distinct visual style, including flipped plus/minus signs for diffs compared to the default Node.js reporter. It is designed for Node.js environments version 18 and newer, with specific recommendations for v22+ for optimal coverage reporting.
