Reporter

Test runner notifies the reporter about various events during test execution. All methods of the reporter are optional.

You can create a custom reporter by implementing a class with some of the reporter methods. Make sure to export this class as default.

TypeScript

// my-awesome-reporter.ts
import { Reporter, FullConfig, Suite, TestCase, TestResult, FullResult } from '@playwright/test/reporter';

class MyReporter implements Reporter {
  constructor(options: { customOption?: string } = {}) {
    console.log(`my-awesome-reporter setup with customOption set to ${options.customOption}`);
  }

  onBegin(config: FullConfig, suite: Suite) {
    console.log(`Starting the run with ${suite.allTests().length} tests`);
  }

  onTestBegin(test: TestCase) {
    console.log(`Starting test ${test.title}`);
  }

  onTestEnd(test: TestCase, result: TestResult) {
    console.log(`Finished test ${test.title}: ${result.status}`);
  }

  onEnd(result: FullResult) {
    console.log(`Finished the run: ${result.status}`);
  }
}
export default MyReporter;

JavaScript

// my-awesome-reporter.js
// @ts-check

/** @implements {import('@playwright/test/reporter').Reporter} */
class MyReporter {
  constructor(options) {
    console.log(`my-awesome-reporter setup with customOption set to ${options.customOption}`);
  }

  onBegin(config, suite) {
    console.log(`Starting the run with ${suite.allTests().length} tests`);
  }

  onTestBegin(test) {
    console.log(`Starting test ${test.title}`);
  }

  onTestEnd(test, result) {
    console.log(`Finished test ${test.title}: ${result.status}`);
  }

  onEnd(result) {
    console.log(`Finished the run: ${result.status}`);
  }
}

module.exports = MyReporter;

Now use this reporter with testConfig.reporter. Learn more about using reporters.

// playwright.config.ts
import { defineConfig } from '@playwright/test';

export default defineConfig({
  reporter: ['./my-awesome-reporter.ts', { customOption: 'some value' }],
});

Here is a typical order of reporter calls:

• reporter.onBegin() is called once with a root suite that contains all other suites and tests. Learn more about suites hierarchy.
• reporter.onTestBegin() is called for each test run. It is given a TestCase that is executed, and a TestResult that is almost empty. Test result will be populated while the test runs (for example, with steps and stdio) and will get final status once the test finishes.
• reporter.onStepBegin() and reporter.onStepEnd() are called for each executed step inside the test. When steps are executed, test run has not finished yet.
• reporter.onTestEnd() is called when test run has finished. By this time, TestResult is complete and you can use testResult.status, testResult.error and more.
• reporter.onEnd() is called once after all tests that should run had finished.

Additionally, reporter.onStdOut() and reporter.onStdErr() are called when standard output is produced in the worker process, possibly during a test execution, and reporter.onError() is called when something went wrong outside of the test execution.

If your custom reporter does not print anything to the terminal, implement reporter.printsToStdio() and return false. This way, Playwright will use one of the standard terminal reporters in addition to your custom reporter to enhance user experience.

Methods

onBegin

Added in: v1.10reporter.onBegin

Called once before running tests. All tests have been already discovered and put into a hierarchy of Suites.

Usage

reporter.onBegin(config, suite);

Arguments

• config TestConfig#

  Resolved configuration.

• suite Suite#

  The root suite that contains all projects, files and test cases.

---

onEnd

Added in: v1.10reporter.onEnd

Called after all tests has been run, or testing has been interrupted. Note that this method may return a Promise and Playwright Test will await it.

Usage

await reporter.onEnd(result);

Arguments

• result Object#
  • status "passed"|"failed"|"timedout"|"interrupted"
  Result of the full test run.
  • 'passed' - Everything went as expected.
  • 'failed' - Any test has failed.
  • 'timedout' - The testConfig.globalTimeout has been reached.
  • 'interrupted' - Interrupted by the user.

---

onError

Added in: v1.10reporter.onError

Called on some global error, for example unhandled exception in the worker process.

Usage

reporter.onError(error);

Arguments

• error TestError#

  The error.

---

onStdErr

Added in: v1.10reporter.onStdErr

Called when something has been written to the standard error in the worker process.

Usage

reporter.onStdErr(chunk, test, result);

Arguments

• chunk string|Buffer#

  Output chunk.

• test void|TestCase#

  Test that was running. Note that output may happen when no test is running, in which case this will be void.

• result void|TestResult#

  Result of the test run, this object gets populated while the test runs.

---

onStdOut

Added in: v1.10reporter.onStdOut

Called when something has been written to the standard output in the worker process.

Usage

reporter.onStdOut(chunk, test, result);

Arguments

• chunk string|Buffer#

  Output chunk.

• test void|TestCase#

  Test that was running. Note that output may happen when no test is running, in which case this will be void.

• result void|TestResult#

  Result of the test run, this object gets populated while the test runs.

---

onStepBegin

Added in: v1.10reporter.onStepBegin

Called when a test step started in the worker process.

Usage

reporter.onStepBegin(test, result, step);

Arguments

• test TestCase#

  Test that the step belongs to.

• result TestResult#

  Result of the test run, this object gets populated while the test runs.

• step TestStep#

  Test step instance that has started.

---

onStepEnd

Added in: v1.10reporter.onStepEnd

Called when a test step finished in the worker process.

Usage

reporter.onStepEnd(test, result, step);

Arguments

• test TestCase#

  Test that the step belongs to.

• result TestResult#

  Result of the test run.

• step TestStep#

  Test step instance that has finished.

---

onTestBegin

Added in: v1.10reporter.onTestBegin

Called after a test has been started in the worker process.

Usage

reporter.onTestBegin(test, result);

Arguments

• test TestCase#

  Test that has been started.

• result TestResult#

  Result of the test run, this object gets populated while the test runs.

---

onTestEnd

  Test that has been finished.

• result TestResult#

  Result of the test run.

---

printsToStdio

Added in: v1.10reporter.printsToStdio

Whether this reporter uses stdio for reporting. When it does not, Playwright Test could add some output to enhance user experience. If your reporter does not print to the terminal, it is strongly recommended to return false.

Usage

reporter.printsToStdio();

Returns

• boolean#
