Slow test reporter for jest

No dependencies, no interactive shell needed. Prints out the slowest 10 tests in your app. Can also print warnings when a test exceeds X ms.

Installation

You may install this package as a development dependency:

npm install --save-dev jest-slow-test-reporter
yarn add --dev jest-slow-test-reporter

Configuration

Configure Jest to use the reporter.

For example, create a jest.config.js file containing:

module.exports = {
  verbose: false,
  reporters: [
    ['jest-slow-test-reporter', {"numTests": 8, "warnOnSlowerThan": 300, "color": true}]
  ]
};

numTests controls how many slow tests to print. warnOnSlowerThan will warn when a test exceeds this time in milliseconds. color will make the warnOnSlowerThan warning messages print in red
