Testing Browser Automation Configuration in PaddleOCR

This test suite configures Jest with Puppeteer for browser-based testing of the PaddleOCR web interface. It establishes a testing environment with Chrome browser automation and a local Python HTTP server for serving test pages.

Test Coverage Overview

The test configuration enables end-to-end browser testing with visual feedback by running Chrome in non-headless mode. Key functionality includes:

Browser automation with Chrome
Local server setup for test pages
Debug mode for troubleshooting
Configurable timeout settings

Implementation Analysis

The testing approach utilizes Jest-Puppeteer integration for automated browser testing. It implements a non-headless Chrome instance for visual verification during test execution, paired with a Python-based HTTP server to serve test content. The configuration leverages Puppeteer’s browser context management and server control capabilities.

Technical Details

Jest-Puppeteer for test automation
Chrome browser in non-headless mode
Python HTTP server on port 9811
10-second launch timeout
Debug mode enabled
Default browser context

Best Practices Demonstrated

The configuration demonstrates several testing best practices including explicit timeout settings, debug mode enablement for troubleshooting, and controlled server management. The setup ensures reproducible test environments with defined browser behavior and server configurations.
