So if I put a console.log
inside a test
the console.log
will appear after the tests eg
authentication.spec.js
register
✓ should be able to insert (128ms)
✓ should fail because of duplicate (100ms)
✓ should have user id assigned (1ms)
login
✓ should be able to login for correct user (117ms)
✓ should fail for incorrect user (14ms)
console.log tests/unit/authentication.spec.js:110
we can see a message
What I would like to see instead is something like:
authentication.spec.js
register
✓ should be able to insert (128ms)
✓ should fail because of duplicate (100ms)
✓ should have user id assigned (1ms)
login
✓ should be able to login for correct user (117ms)
console.log tests/unit/authentication.spec.js:110
we can see a message
✓ should fail for incorrect user (14ms)
So the console.log
should be appearing with ✓ should be able to login for correct user
in this case
When I was using Mocha I was using mocha-logger
As far as I know this is not easily possible, though a couple of places to look for more information (not out of the box):
Jest allows to use custom reporters: https://jestjs.io/docs/en/configuration.html#reporters-array-modulename-modulename-options , so you can write your own reporter and display output differently. At the moment though you don't get updates for separate tests, just test suits, here is an issue created by Dan Abramov: https://github.com/facebook/jest/issues/6616 .
From the github thread above - Reporter interface for now looks like:
export default class BaseReporter {
onRunStart(results: AggregatedResult, options: ReporterOnStartOptions) {}
// these are actually for the test suite, not individual test results
onTestStart(test: Test) {}
onTestResult(test: Test, testResult: TestResult, results: AggregatedResult) {}
onRunComplete(contexts: Set<Context>, results: AggregatedResult ): ?Promise<void> {}
}
I didn't find a predefined way to pass parameters from test though into the testResult
object. So you are mostly limited to logging information based on test names. Below is an example of testResult
property inside testResult
object:
testResults:
[ { ancestorTitles: [Array],
duration: 5,
failureMessages: [],
fullName: 'add should add two numbers',
location: null,
numPassingAsserts: 0,
status: 'passed',
title: 'should add two numbers' } ],
As you can see this is all the information standard reporter uses: test name, duration, status. For reference the default reporter is here: https://github.com/facebook/jest/blob/7b7fd01350/packages/jest-cli/src/reporters/default_reporter.js
Yes, you can have it logged. You may need to Add --verbose false
to package.json "test"
;
Ex: "scripts": { "test": "jest --watch --verbose false" }
