Selenium series: modifying HTTP requests

The blog post by Matthew Casperson explores the use of the BrowserMob proxy tool within a Selenium WebDriver test framework to manipulate network requests, enhancing testing efficiency by blocking unnecessary assets and simulating service failures. It explains the implementation of a method called `blockRequestTo`, which allows users to intercept requests to specific URLs and return predefined HTTP response codes, thereby controlling what content is loaded during tests. This approach can optimize test performance by preventing the loading of non-essential elements such as images and blocking third-party services, which can help in simulating scenarios like external service failures. Additionally, the post highlights the importance of managing proxy settings manually after tests are completed, as the BrowserMob proxy's closure stops the browser's network communication, necessitating manual adjustments for further interactions with the web page.
