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.
