Playwright Testing for E-Commerce Product Search and Filter Interactions

Automate faceted search filters, sort options, pagination, and search result relevance validation for e-commerce product catalog pages. This guide provides step-by-step Playwright patterns to handle this scenario reliably.

Introduction

Robust automation requires handling domain-specific patterns effectively. This article covers playwright testing for e-commerce product search and filter interactions with production-ready Playwright code.

Architecture Overview

graph TD
    Search["Search Input"] --> API["Search API"]
    API --> Facets["Filter Options"]
    Facets --> Apply["Apply Filter"]
    Apply --> Results["Filtered Products"]
    Results --> Sort["Sort Order"]

Implementation Guide

test('product filters narrow results correctly', async ({ page }) => {
  await page.goto('/products');
  const initialCount = await page.getByTestId('product-card').count();

  // Apply brand filter
  await page.getByLabel('Brand').getByText('Nike').check();
  await page.waitForResponse('/api/products');

  const filteredCount = await page.getByTestId('product-card').count();
  expect(filteredCount).toBeLessThan(initialCount);

  // Verify filter chip appears
  await expect(page.getByTestId('active-filter')).toContainText('Nike');
});
