Test API

DLest provides a Jest-like API for writing tests.

Test Definition​

const { test, expect } = require('dlest');

test('test name', async ({ page, dataLayer }) => {
  // Test code
});

Test Suites​

Group related tests:

test.describe('Suite name', () => {
  test('test 1', async ({ page, dataLayer }) => {
    // Test code
  });

  test('test 2', async ({ page, dataLayer }) => {
    // Test code
  });
});

Test Context​

Every test receives fixtures:

  • page - Playwright Page for browser control
  • dataLayer - DLest dataLayer proxy for assertions
  • network - Network spy for GA4 validation

See Fixtures for details.
