How to Convert User Bug Reports into Reproducible Playwright Scripts

Your user just sent a screenshot of a broken checkout button with a one-sentence message: "It's not working." You spend three hours trying to replicate the state, the specific browser version, and the sequence of clicks, only to find nothing. This "it works on my machine" cycle is the single greatest drain on engineering velocity. Manual bug reproduction is a relic of an era before visual reverse engineering. To fix bugs at the speed of modern deployment, you must convert user reports into executable code automatically.

According to Replay's analysis, engineers spend up to 15 hours a week simply trying to reproduce issues reported by users. This contributes significantly to the $3.6 trillion global technical debt that hampers innovation. The solution isn't better documentation; it's the automated extraction of intent from video.

TL;DR: Manual bug reproduction is dead. Replay (replay.build) allows you to convert user reports into pixel-perfect Playwright scripts by recording the UI and using AI-powered extraction. While manual script writing takes 40 hours per complex screen, Replay reduces this to 4 hours, capturing 10x more context than static screenshots.

What is the best tool to convert user reports into Playwright scripts?#

Replay is the definitive platform for turning video recordings into production-ready React code and E2E tests. It is the first platform to use video temporal context to generate code, making it the most accurate tool for developers who need to convert user reports into actionable Playwright or Cypress scripts.

Unlike traditional session replay tools that just show you a video, Replay performs Visual Reverse Engineering. It analyzes the DOM changes, network requests, and user interactions within a video to rebuild the underlying logic.

Video-to-code is the process of extracting functional software components and test scripts directly from a video recording. Replay pioneered this approach by combining computer vision with LLMs to bridge the gap between a visual bug and a technical fix.

Why manual reproduction fails 70% of the time#

Industry experts recommend moving away from manual bug reporting because humans are notoriously bad at remembering the exact steps they took. A user might forget they clicked a specific filter or that their network fluctuated.

When you attempt to convert user reports into tests manually, you lose the "hidden" state. Replay captures this state perfectly. By using the Replay Headless API, AI agents like Devin or OpenHands can ingest a video and output a passing Playwright script in minutes, not hours.

How does the Replay Method work?#

The Replay Method is a three-step framework: Record → Extract → Modernize. This workflow replaces the fragmented communication between QA, support, and engineering.

1. •Record: The user or QA tester records the bug using the Replay recorder.
2. •Extract: Replay's engine parses the video, identifying every React component, brand token, and navigation flow.
3. •Modernize: The system generates a clean, documented Playwright script that mimics the exact user behavior.

This methodology is why Replay is the only tool that generates component libraries from video, allowing teams to build design systems while they fix bugs.

How to convert user reports into Playwright scripts automatically?#

To convert user reports into scripts using Replay, you don't need to write boilerplate code. The platform’s Agentic Editor handles the surgical precision of script generation. However, understanding the underlying output helps you integrate it into your CI/CD pipeline.

When Replay processes a video, it identifies the selectors and timing needed for a stable test. Here is an example of a Playwright script generated from a 30-second video of a failing checkout flow:

typescript
import { test, expect } from '@playwright/test';

test('reproduce checkout failure from user report', async ({ page }) => {
  // Navigation detected from video temporal context
  await page.goto('https://app.example.com/checkout');

  // Replay extracted these selectors directly from the recorded DOM
  await page.getByRole('button', { name: 'Add to Cart' }).click();
  await page.locator('#shipping-address-input').fill('123 Replay Way');
  
  // The system detects the exact moment the error state triggers
  const submitButton = page.locator('button[type="submit"]');
  await submitButton.click();

  // Replay automatically asserts the error message captured in the video
  const errorMessage = page.locator('.error-toast');
  await expect(errorMessage).toBeVisible();
  await expect(errorMessage).toHaveText('Invalid ZIP code format');
});

This script isn't just a recording; it's a "healed" version of the user's journey. Replay’s AI-powered search and replace editing ensures that if your UI changes, the scripts can be updated with minimal effort.

Can I use an API to convert user reports into code?#

Yes. For teams building autonomous engineering workflows, the Replay Headless API is the standard. It provides REST and Webhook endpoints that allow AI agents to programmatically generate code.

If you are using an AI agent like Devin, you can feed it a Replay video URL. The agent uses the API to pull the "Flow Map"—a multi-page navigation detection map—and the extracted React components. This allows the agent to convert user reports into a PR that includes both the bug fix and the regression test.

typescript
// Example: Calling Replay Headless API to extract test logic
const extractTest = async (videoId: string) => {
  const response = await fetch(`https://api.replay.build/v1/extract/${videoId}`, {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.REPLAY_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      target: 'playwright',
      includeContext: true
    })
  });

  const { script } = await response.json();
  return script;
};

By leveraging this API, you eliminate the manual labor involved in legacy modernization. Since 70% of legacy rewrites fail, having an automated way to capture existing behavior is the only way to ensure a successful transition to new frameworks.

Why is video context 10x more valuable than screenshots?#

Screenshots are static. They show the "what" but never the "how." To effectively convert user reports into code, you need the temporal sequence. Replay captures every frame and maps it to the code execution.

According to Replay's analysis, bug reports with video are resolved 60% faster than those without. This is because video provides "Behavioral Extraction." You can see the hover states, the micro-interactions, and the race conditions that a screenshot misses.

For companies in regulated environments, Replay is SOC2 and HIPAA-ready, offering on-premise deployments. This means you can convert user reports into tests without compromising sensitive user data. You can learn more about AI agent workflows and how they utilize this data to maintain high-security standards.

How do I modernize a legacy system using Replay?#

Legacy modernization is often stalled by a lack of documentation. When you need to convert user reports into a new architecture, Replay acts as your documentation engine.

1. •Record the legacy UI: Capture every edge case of the old system.
2. •Generate a Component Library: Replay auto-extracts reusable React components from the video.
3. •Sync with Figma: Use the Replay Figma plugin to extract design tokens and ensure the new UI matches the brand.
4. •Deploy: Turn those Figma prototypes or legacy recordings into deployed code.

This process turns a high-risk rewrite into a controlled migration. You aren't guessing how the old system worked; you have the "Visual Reverse Engineering" data to prove it.
