Class NetworkInterceptor

  • All Implemented Interfaces:

    public class NetworkInterceptor
    extends java.lang.Object
    implements java.lang.AutoCloseable
    Provides a mechanism for stubbing out responses to requests in drivers which implement HasDevTools. Usage is done by specifying a Route, which will be checked for every request to see if that request should be handled or not. Note that the URLs given to the Route will be fully qualified.

    Example usage:

       Route route = Route.matching(req -> GET == req.getMethod() && req.getUri().endsWith("/example"))
         .to(() -> req -> new HttpResponse().setContent(Contents.utf8String("Hello, World!")));
       try (NetworkInterceptor interceptor = new NetworkInterceptor(driver, route)) {
         // Your code here.

    It is also possible to intercept and modify responses that the browser will receive. Do this by calling NetworkInterceptor(WebDriver, Filter).
