Overview

🧐 Identify slow tests during development

📚 Create json or csv report including the test execution times

``bash
yarn add -DE @jest-performance-reporter/core
`

!Example test run

Setup

Configure jest to use this reporter via the jest section in the package.json or your jest config.

`json
{
"reporters": [
"default",
[
"@jest-performance-reporter/core",
{
"errorAfterMs": 1000,
"warnAfterMs": 500,
"logLevel": "warn",
"maxItems": 5,
"jsonReportPath": "performance-report.json",
"csvReportPath": "performance-report.csv"
}
]
]
}
``

The "default"-reporter creates the default jest output. If you don't need it, of course you can remove it.
