はじめに

Playwright allows setting up proxies globally for the entire browser or individually for each browser context.
To set a global proxy, the configuration can be specified in [playwright.config.ts](prompt://ask_markdown?question=playwright.config.ts).
Proxy setup requires specifying the server, port, and optionally, a username and password for authentication.
Playwright can handle HTTP(S) proxies as well as SOCKS5 proxies.
Configuration is done through the 'use' section in the Playwright configuration, where parameters like proxy server and credentials are included.
Using proxies in Playwright can help simulate user behavior from different regions and assist in accurate testing and analysis.

Playwright supports setting proxies either globally or per browser context, enabling flexible configurations.
A global proxy is configured in the Playwright playwright.config.ts file, outlining server details.
To achieve precise regional testing, proxies simulate users operating from specific geographical locations.
Proxies can help in bypassing IP restrictions imposed by certain websites during automated testing.
Playwright also supports handling proxies programmatically through its API.

Global proxy setup involves specifying the proxy details in the Playwright configuration file.
The playwright.config.ts file is used to define the proxy server, ports, and any authentication details.
This configuration applies to all browser instances launched by Playwright.
Global settings are useful for consistent proxy use across all tests and sessions.
Such configurations help ensure all HTTP requests go through a proxy for data fetching or scraping.

In Playwright, proxies can be set for individual browser contexts, allowing tailored configurations for specific tests.
context-specific settings are often used when different proxies are needed for different test cases or scenarios.
Playwright offers options to specify both proxy servers and bypass hosts in each context.
This method permits fine-grained control over which requests go through the proxy.
Such flexibility is essential for testing applications that rely on context-specific network configurations.

When using proxies that require authentication, Playwright allows the specification of credentials directly in the configuration.
Credentials include username and password fields within the proxy configuration setup.
Authentication is crucial to access secure proxies and ensure authorized usage.
Playwright provides mechanisms for both HTTP and HTTPS proxy authentications.
Properly configured authentication ensures seamless integration with proxy services during test execution.

Using proxies with Playwright enhances test accuracy by simulating real-world conditions from different locations.
They help avoid IP bans during aggressive web scraping or automated testing.
Proxies increase anonymity and reduce the risk of being flagged by websites as bot activity.
By leveraging different IPs, users secure varied and robust test coverage for their applications.
In cases of regional content delivery, proxies allow testing of geo-restricted data and services.
