Reporter for node:test that supports colorful diffs etc
npm install @voxpelli/node-test-pretty-reporterReporter for node:test that supports colorful diffs etc






``sh`
npm install -D @voxpelli/node-test-pretty-reporter
`sh`
node --test --test-reporter=@voxpelli/node-test-pretty-reporter
This one is similar to the built-in spec reporter but differs in some ways which I personally prefer.
Outputs colored diffs when a test is failed with an Error that has expected and actual properties (respecting a showDiff property set to false).
Diff is generated by jest-diff (no other part of jest is used in this reporter).
Assertion libraries that outputs compatible errors:
* node:assert
* chai (note: chai.should() breaks error presentation since 18.17.0, see: voxpelli/node-test-pretty-reporter#6, nodejs/node#48918, chaijs/chai#1530)
As with other changes, this makes the reporter on par with Mocha.
The output styling aligns more with Mocha's spec reporter:
* ~~Errors are presented at the end instead of in the list of tests~~ _(also done in built in since nodejs/node#47164)_
* Less visually intense, eg. no ▶ in front of names and only failed tests gets colored
* Durations are only reported if considered slow (using same default as Mocha: 75ms)
* No redundant mentioning of a test suite after the suite has completed – opts for a clean tree from top to bottom instead
When used with at least Node 18.17.0 or 20.2.0 this is supported (see issue #2).
Since those same versions the cause chain is also printed in the built in spec reporter, but done through util.inspect() there rather than the custom output here.
I have not tested any of these myself yet so can't say if they work well or not, but adding here for reference.
