jest-slow-test-highlighter

A custom Jest reporter that identifies and reports on the slowest running tests in your test suite.

Installation

Install the package using npm:

npm install jest-slow-test-highlighter --save-dev

Usage

In your Jest configuration file (e.g., jest.config.js), add jest-slow-test-highlighter to your list of reporters:

module.exports = {
  // ... other Jest configuration options
  reporters: ["default", "jest-slow-test-highlighter"]
};

Configuration Options

You can customize the behavior of the reporter by providing configuration options:

module.exports = {
  // ... other Jest configuration options
  reporters: [
    "default",
    ["jest-slow-test-highlighter", {
      maxTests: 10, // Maximum number of slow tests to display. Default is 10.
      slowSeconds: 5 // Threshold in seconds to consider a test as "slow". Default is 5 seconds.
    }]
  ]
};

Options

• maxTests: Determines the maximum number of slow tests to display in the report. Default value is 10.

• slowSeconds: The threshold in seconds to classify a test as "slow". Any test that runs longer than this threshold will be considered slow and will be reported. Default value is 5 seconds.
