Package description

What is @jest/reporters?

The @jest/reporters package provides utilities for handling and customizing the output of test results when using Jest, a popular JavaScript testing framework. It allows developers to create custom reporters to modify how test results are reported, making it easier to integrate with various CI tools, generate reports in different formats, or enhance the testing experience with additional logging and notifications.

What are @jest/reporters's main functionalities?

Custom Test Reporter

This feature allows developers to create a custom test reporter by implementing methods that Jest calls at different stages of the test run. The example shows a basic custom reporter that logs messages at the start and end of the test suite, as well as after each test result.

class MyCustomReporter {
  onRunStart(results, options) {
    console.log('Test suite started');
  }

  onTestResult(test, testResult, aggregatedResult) {
    console.log(`Test ${test.path} finished with ${testResult.numFailingTests} failures`);
  }

  onRunComplete(contexts, results) {
    console.log('All tests completed');
  }
}

module.exports = MyCustomReporter;
