Jest

npm install @tracera/jest

Tested on Node.js 22.19–26.12 and Jest 30–30.5 (see Autotest adapters). @tracera/jest on npm.

In jest.config.cjs (or your Jest config):

module.exports = {
  testEnvironment: 'node',
  setupFilesAfterEnv: ['@tracera/jest/setup'],
  reporters: ['default', '@tracera/jest/reporter'],
};

Environment variables, run mode, and retries: Autotest adapters.

Retry Env key: JEST_RETRY.

Bind `testCaseId` and `autotestName`

Import test, expect, and hooks from @jest/globals (or use Jest-injected globals), and tracera, annotations, and skip from @tracera/jest. Load @tracera/jest/setup so steps and bind work with stock Jest APIs.

At declaration (preferred — bind runs even if the body skips early):

import { test, expect } from '@jest/globals';
import { annotations } from '@tracera/jest';

test(
  'login',
  annotations(42, 'e2e/login', async () => {
    expect(true).toBe(true);
  }),
);

Inside the test (optional if annotations already bind the case):

import { test, expect } from '@jest/globals';
import { tracera } from '@tracera/jest';

test('login', async () => {
  tracera.testCase(42, 'e2e/login');
  expect(true).toBe(true);
});

Skip

If you already know the test should be skipped — use test.skip or describe.skip. If the skip condition is computed inside the test — use skip from this package: Jest has no test.skip(reason).

import { test } from '@jest/globals';
import { annotations, skip } from '@tracera/jest';

test(
  'login',
  annotations(42, 'e2e/login', () => {
    if (!process.env.READY) skip('env not ready');
    // …
  }),
);

Steps

Use tracera.step: the call tracera.step(title, fn), @tracera.step("…") on a class method, or tracera.step("…")(fn). In a decorator title, {name} / {0} are filled from the method arguments; you can also pass a function that returns the title. In the call form, {name} / {0} are not filled in — pass a finished title string (or build it yourself). Async methods and Promises are awaited. Stock beforeEach / afterEach from @jest/globals are instrumented: steps inside them go to the result’s Setup / Teardown. Suite-level hooks such as beforeAll / afterAll are not reported.

import { test, beforeEach, afterEach } from '@jest/globals';
import { tracera } from '@tracera/jest';

beforeEach(async () => {
  await tracera.step('open shop', async () => {
    // …
  });
});

test('checkout', async () => {
  tracera.testCase(10, 'e2e/checkout');
  await tracera.step('add to cart', async () => {
    // …
  });
});

afterEach(async () => {
  await tracera.step('cleanup', async () => {
    // …
  });
});

Decorator on a method:

import { tracera } from '@tracera/jest';

class Cart {
  @tracera.step('add {item}')
  async addToCart(item: string) {
    // …
  }
}

Comments, errors, and attachments

Comments, errors, and attachments: Autotest adapters.

import { test } from '@jest/globals';
import { tracera } from '@tracera/jest';

test('login', async () => {
  tracera.testCase(42, 'e2e/login');
  tracera.comment('result-level note');
  tracera.error('result-level error text');

  await tracera.step('open login', async () => {
    tracera.comment('landed on login');
    tracera.attachment({
      fileName: 'suite-log.txt',
      mimeType: 'text/plain',
      data: new TextEncoder().encode('finished login flow'),
    });
  });
});

Parameterized tests

With test.each, wrap the callback: annotations(id, 'login as {login}', fn) so fields from the row object fill {login} and similar placeholders.
