Playwright Testing for Australian Banking Open Finance APIs

Region Focus: This guide includes examples and patterns specifically relevant to Australia-based development teams and applications.

Modern web applications require thorough testing strategies that account for regional requirements, diverse user bases, and complex technical architectures. This guide provides actionable Playwright patterns for your specific context.

Introduction

Test Australian CDR (Consumer Data Right) consent flows, bank data sharing, and accredited data recipient validation with Playwright. This guide covers the essential patterns, configurations, and strategies to handle this scenario reliably in your Playwright test suite.

Understanding the nuances of this topic allows your team to ship with confidence, reduce flakiness, and maintain high-quality automation across different environments.

Architecture Overview

Step-by-Step Guide

Follow this implementation to set up the pattern in your test suite.

1. Core Implementation

test('Australian CDR consent is captured correctly', async ({ page }) => {
  await page.goto('/connect-bank');
  await page.getByRole('combobox', { name: 'Select your bank' }).selectOption('Commonwealth Bank');
  await page.getByRole('button', { name: 'Connect' }).click();
  // Mock CDR consent redirect
  await expect(page.getByText('Sharing data securely with CBA')).toBeVisible();
  await page.getByRole('button', { name: 'Authorise' }).click();
  await expect(page.getByText('Connected successfully')).toBeVisible();
});

2. Run and Verify

# Run this specific test file
npx playwright test --grep "Playwright Testing for"

Run with UI mode for debugging
npx playwright test --ui

Run across all browsers
npx playwright test --project=chromium --project=firefox --project=webkit

Frequently Asked Questions

What is CDR and how does it affect Playwright tests?

CDR (Consumer Data Right) is Australia's Open Banking framework. Test consent flows and verify data sharing works correctly.

How to test CDR consent duration selection?

Verify that date picker allows selecting sharing duration up to 12 months as per CDR rules.

Can Playwright test ACCC-compliant consent receipts?

Yes, after consent, verify that the consent receipt is displayed with all required ACCC fields.

How to test Australian bank's myGovID authentication?

Mock the myGovID OAuth flow and verify your app handles the identity verification callback correctly.

How to test CDR data sharing revocation?

Navigate to the consent management screen and verify that revocation deletes the access token.

Summary

Test Australian CDR (Consumer Data Right) consent flows, bank data sharing, and accredited data recipient validation with Playwright. By following these patterns, your team can build a reliable, maintainable automation suite that works across environments and handles edge cases gracefully.
